Vocalizations of anuran amphibians have received much attention in studies of behavioral ecology and physiology, but also provide informative characters for identifying and delimiting species. We here review the terminology and variation of frog calls from a perspective of integrative taxonomy, and provide hands-on protocols for recording, analyzing, comparing, interpreting and describing these sounds. Our focus is on advertisement calls, which serve as premating isolation mechanisms and, therefore, convey important taxonomic information. We provide recommendations for terminology of frog vocalizations, with call, note and pulse being the fundamental subunits to be used in descriptions and comparisons. However, due to the complexity and diversity of these signals, an unequivocal application of the terms call and note can be challenging. We therefore provide two coherent concepts that either follow a note-centered approach (defining uninterrupted units of sound as notes, and their entirety as call) or a call-centered approach (defining uninterrupted units as call whenever they are…

We provide a map of the 14 biogeographic provinces of Mexico based on the ecoregions recognized for the country, which combine climatic, geological and biotic criteria. These provinces belong to the Nearctic region (Californian, Baja Californian, Sonoran, Chihuahuan Desert and Tamaulipas provinces), Neotropical region (Pacific Lowlands, Balsas Basin, Veracruzan and Yucatán Peninsula provinces) and the Mexican transition zone (Sierra Madre Occidental, Sierra Madre Oriental, Transmexican Volcanic Belt, Sierra Madre del Sur and Chiapas Highlands provinces). In order to facilitate future biogeographic analyses, we provide a file of the biogeographical regionalisation of Mexico by converting the map into a polygon shapefile and a raster file with all provinces. We also separately provide each of the provinces in vector and raster format. All the maps are in geographical and Lambert Conformal Conic projections.

The Mexican transition zone (MTZ) is the complex area where the Neotropical and Nearctic biotas overlap, including south-western United States, Mexico and a large part of Central America extending to the Nicaraguan lowlands. In a strict sense, it corresponds to the mountain highlands of Mexico, Guatemala, Honduras, El Salvador and Nicaragua. We review Halffter's theory explaining the biotic evolution of the MTZ, including the description and discussion of the distributional patterns and cenocrons recognized within it. Distributional patterns are generalizations that help analyse and compare distributions of different taxa. Cenocrons correspond to sets of taxa that share the same biogeographic history, constituting identifiable subsets within the transitional biota by their common biotic origin and evolutionary history. The heuristic value of distributional patterns and cenocrons lies in their application to formulate hypotheses on biotic assembly in the geographical-ecological space, to analyse the ecological response to anthropic impact, to analyse altitudinal patterns and to…

A classification is proposed for the order Amphipoda. The Amphipoda includes six suborders, the Pseudingolfiellidea, Hyperiidea, Colomastigidea, Hyperiopsidea, Senticaudata (described in a previous contribution (Lowry & Myers 2013)) and Amphilochidea. The suborder Ingolfiellidea is raised to order status. A cladistic tree, based on morphology, is presented illustrating the relationships of the Amphipoda at parvorder level. A tree for the families of the Physomatidira and Physocephalatidira, a tree for the Maxillipiidira, Oedicerotidira, Eusiridira and Amphilochidira and a tree for the Synopiidira, Haustoriidira and Lysianassidira, are provided. Families are listed together with their included genera. New families are diagnosed.

Species of the Macrobiotus hufelandi group are one of the most often recorded tardigrades throughout the globe. For over a century M. hufelandi has been considered cosmopolitan but in recent decades numerous species of similar morphologies have been described from various continents, which suggests that what was originally defined as a single taxon is, in fact, a complex of species. The definition of the hufelandi group is subject to a long-standing discussion and in this paper we propose a refined set of characters that are hoped to elucidate the taxonomic status of the group. In order to aid interspecific comparisons, we also propose a unified nomenclature for the crucial morphological traits and clar.

The taxonomic identity and status of the Australian Dingo has been unsettled and controversial since its initial description in 1792. Since that time it has been referred to by various names including Canis dingo, Canis lupus dingo, Canis familiaris and Canis familiaris dingo. Of these names C. l. dingo and C. f. dingo have been most often used, but it has recently been proposed that the Australian Dingo should be once again recognized as a full species—Canis dingo. There is an urgent need to address the instability of the names referring to the Dingo because of the consequences for management and policy. Therefore, the objective of this study was to assess the morphological, genetic, ecological and biological data to determine the taxonomic relationships of the Dingo with the aim of confirming the correct scientific name. The recent proposal for Canis dingo as the most appropriate name is not sustainable under zoological nomenclature protocols nor based on the genetic and morphological evidence. Instead we proffer the name C. familiaris for all free-ranging dogs, regardless of…

Responding to purported taxonomic anarchy, in an article published in the widely read journal Nature, Garnett & Christidis (2017) [hereafter GC] opined on the need for “standardized global species lists”, at the behest of conservationists, and proposed the construction of a judicial committee to “restrict … freedom of taxonomic action” and promote taxonomic stability. Here we reflect on this perspective and contest that the view of GC conflicts with some basic and indisputable principles underpinning the philosophy of science, most notably: it must be free. They appear to believe that taxonomic revisions should be based on political, economic and conservation concerns, and they treat species as fixed real entities, instead of refutable scientific hypotheses. In addition to such theoretical misconceptions, GC did not consider important practical aspects of what they term taxonomic anarchy, most significantly the participation of conservationists as authors of taxonomic works, and the importance of alternative management units, a well-established discussion in conservation biology.

The genus Brueelia Kéler, 1936a forms the core of the so-called “Brueelia-complex”, one of the largest and most heterogeneous groups of lice (Phthiraptera). Here we introduce the taxonomic history and present a revision of this group. The limits of the Brueelia-complex are discussed. We resurrect the genera Acronirmus Eichler, 1953, Corvonirmus Eichler, 1944, Guimaraesiella Eichler, 1949, Maculinirmus Złotorzycka, 1964a, Meropsiella Conci, 1941a, Olivinirmus Złotorzycka, 1964a, Osculonirmus Mey, 1982a, Rostrinirmus Złotorzycka, 1964a, Traihoriella Ansari, 1947, and Turdinirmus Eichler, 1951. We describe the following new genera: Anarchonirmus n. gen., Aporisticeras n. gen., Aratricerca n. gen., Buphagoecus n. gen., Ceratocista n. gen., Sychraella n. gen., Couala n. gen., Harpactrox n. gen., Hecatrishula n. gen., Indoceoplanetes n. gen., Manucodicola n. gen., Mirandofures n. gen., Nemuus n. gen., Priceiella n. gen., Psammonirmus n. gen., Resartor n. gen., Saepocephalum n. gen., Schizosairhynchus n. gen., Teinomordeus n. gen., Titanomessor n. gen., and Turdinirmoides n. gen.; and the…

Marbled crayfish are a globally expanding population of parthenogenetically reproducing freshwater decapods. They are closely related to the sexually reproducing slough crayfish, Procambarus fallax, which is native to the southeastern United States. Previous studies have shown that marbled crayfish are morphologically very similar to P. fallax. However, different fitness traits, reproductive incompatibility and substantial genetic differences suggest that the marbled crayfish should be considered an independent species. This article provides its formal description and scientific name, Procambarus virginalis sp. nov.

The state of Michigan occupies an area between the Great Plains and the northeastern United States, bordering four Great Lakes, with diverse biogeographical regions. Michigan also has the second most diverse agriculture in the country, with many crops that depend on bees for pollination. This unique combination provides a wide range of opportunities for bees to persist, yet there is no current published checklist of these important insects. This study was conducted to provide the first annotated checklist of the bee (Apoidea: Anthophila) fauna of Michigan, summarizing aspects of their taxonomy and behavior and to provide provisional conservation assessment. The list was compiled from a critical review of published literature, museum specimens, and database records, supplemented by new collections. In total, 465 species are included in the checklist, including 38 new records, however evidence for 13 species is poor, several more species require taxonomic revision, and the presence of additional species is expected. The exotic megachilid species Megachile apicalis Spinola, M. pusilla…

The paper contains a review of coleopteran genera known from Baltic, Bitterfeld and Rovno amber localities. Altogether 420 genera (191 extinct and 229 extant) from 78 families are listed from these three Lagerstätten (as of 7 March 2017). The listed beetles were analyzed zoogeographically and distributional maps for 72 genera were compiled. One-quarter (56) of the genera that have survived since the Eocene have cosmopolitan ranges at present; 35 extant genera have been extripated from the Palaearctic since the Eocene. Approximately 40% of beetle genera from the middle-upper Eocene European ambers can be encountered in the wild in present-day Europe, while 5 of these genera are supposed to be European relict endemics originating in Fennosarmatia. The general similarity of the Baltic amber (s.l.) beetle assemblage to modern south Palaearctic fauna is the strongest, the Nearctic elements are more numerous in the middle-upper Eocene European ambers than the Oriental taxa. The simplified Mutual Climatic Range (MCR) method was used for palaeoclimate reconstruction based on fossil beetles.…

A population of Ramazzottius subanomalus (Biserov, 1985) was found in a moss sample collected from concrete wall in Poznań, western Poland. Animals were prepared for light and scanning electron microscopy and for DNA sequencing to provide an integrative description of the species that was originally described only by means of classical alpha taxonomy. As a result of our studies, we provide the first ever SEM photomicrographs of Ramazzottius subanomalus individuals and their buccal apparatuses. Additionally, we present new DNA sequences as well as new morphometric data for R. subanomalus. The molecular data comprise sequences for three DNA fragments, one mitochondrial (COI) and two nuclear (18S rRNA and 28S rRNA). As a result of being able to analyse a considerable number of animals and eggs, our study has expanded some of R. subanomalus morphometric traits ranges; compared with those provided in the original description. The spine-shaped egg processes as well as qualitative and quantitative characters of adults show R. subanomalus is most similar to Ramazzottius anomalus…

This paper is the fourth monograph in a series that describes the global records of limno-terrestrial water bears (Tardigrada). Here, we provide a comprehensive list of non-marine tardigrades recorded from Africa, providing an updated and revised taxonomy accompanied by geographic co-ordinates, habitat, and biogeographic comments. It is hoped this work will serve as a reference point and background for further zoogeographical and taxonomical studies.

Northern Australia is biologically diverse and of national and global conservation signicance. Its ancient landscape contains the world's largest area of savannah ecosystem in good ecological condition and its rivers are largely free-flowing. Agriculture, previously confined largely to open range-land grazing, is set to expand in extent and to focus much more on irrigated cropping and horticulture. Demands on the water resources of the region are thus, inevitably increasing. Reliable information is required to guide and inform development and help plan for a sustainable future for the region which includes healthy rivers that contain diverse fish assemblages. Based on a range of information sources, including the outcomes of recent and extensive new field surveys, this study maps the distribution of the 111 freshwater fishes (excluding elasmobranches) and 42 estuarine vagrants recorded from freshwater habitats of the region. We classify the habitat use and migratory biology of each species. This study provides a comprehensive assessment of the diversity and distribution of fishes of…

A wide range of aspects concerning microscope slides, their preparation, long-time storage, curatorial measures in collections, deterioration, restoration, and study is summarized based on our own data and by analyzing more than 600 references from the 19th century until 2016, 15 patents, and about 100 Materials Safety Data Sheets. Information from systematic zoology, conservation sciences, chemistry, forensic sciences, pathology, paleopathology, applied sciences like food industry, and most recent advances in digital imaging are put together in order to obtain a better understanding of which and possibly why mounting media and coverslip seals deteriorate, how slides can be salvaged, which studies may be necessary to identify a range of ideal mounting media, and how microscope studies can benefit from improvements in developmental biology and related fields. We also elaborate on confusing usage of concepts like that of maceration and of clearing. The chemical ingredients of a range of mounting media and coverslip seals are identified as much as possible from published data, but this…

This is an identification guide to the 47 currently described genera of marine heterotardigrades. We provide clear definitions and illustrations of relevant anatomy and an easy to use dichotomous key. The aim of the present contribution is to enable more people to identify collected specimens of marine heterotardigrades, and hopefully, encourage more people to study this intriguing group of animals. The paper is divided into three parts. The first part gives a brief introduction to heterotardigrade morphology with special emphasis on taxonomically important characters. The second part is the actual key, which is accompanied by illustrations of both habitus and detailed foot morphology of the marine heterotardigrade genera. The third part provides up to date diagnoses of the orders, families, subfamilies and genera of marine heterotardigrades according to the most recent emendments. With the generic diagnoses, we provide a bibliography with selected literature that relates to each specific genus.

Genus-level taxa in the oribatid mite superfamily Galumnoidea (Acari, Oribatida) are revised based on morphology of adults and a previously published phylogenetic analysis. We give a concise overview of the general morphology of Galumnoidea, diagnoses and a key for families, genera, and subgenera, and a taxonomic list with two families, 39 genera, 9 non-nominal subgenera, and 590 species. The following nomenclatorial changes to genus-group taxa resulted from our revision: Allogalumna (Allogalumna) Grandjean, 1936 (=Xenogalumna Balogh, 1960(b) syn. nov.), Flagellozetes (Cosmogalumna) Aoki, 1988 comb. nov. (from Galumna (Cosmogalumna)), Flagellozetes (Variogalumna) Mahunka, 1995 stat. nov., Galumna (Galumna) Heyden, 1826 (=Rostrogalumna Engelbrecht, 1973 syn. nov.), Pilogalumna Grandjean, 1956(a) (=Disparagalumna Hammer, 1973 syn. nov.), Trichogalumna (Tanzanycha) Koçak & Kemal, 2008 stat. nov., Galumnella Berlese, 1916(a) (=Monogalumnella Mahunka, 1986 syn. nov. =Trichogalumnella Mahunka, 1992 syn. nov., =Bigalumnella Mahunka, 1994 syn. nov.). The following changes are made to…

Pseudoliparis swirei sp. nov. is described from 37 individuals collected in the Mariana Trench at depths 6898-7966 m. The collection of this new species is the deepest benthic capture of a vertebrate with corroborated depth data. Here, we describe P. swirei sp. nov. and discuss aspects of its morphology, biology, distribution, and phylogenetic relationships to other hadal liparids based on analysis of three mitochondrial genes. Pseudoliparis swirei sp. nov. is almost certainly endemic to the Mariana Trench, as other hadal liparids appear isolated to a single trench/ trench system in the Kermadec, Macquarie, South Sandwich, South Orkney, Peru-Chile, Kurile-Kamchatka and Japan trenches. The discovery of another hadal liparid species, apparently abundant at depths where other fish species are few and only found in low numbers, provides further evidence for the dominance of this family among the hadal fish fauna.

Sponges collected on the Guyana Shelf, predominantly in Suriname offshore waters, by Dutch HMS 'Snellius' O.C.P.S. 1966, HMS 'Luymes' O.C.P.S. II 1969, and HMS 'Luymes' Guyana Shelf 1970 expeditions are described in this study. Sponges were obtained by trawling, dredging or grabbing on sandy, muddy, shelly, and fossil reef bottoms at 88 stations between 19 and 681 m depth. A total of 351 samples were identified to species level, each consisting of one or more specimens of a given species from each individual station (together comprising 547 individuals and fragments). The collection yielded 119 species together belonging to all sponge classes, but in large majority are Demospongiae. All species are identified to species level, occasionally tentatively, and all are described and illustrated. A new subgenus is proposed, Tedania (Stylotedania) subgen. nov. and a previously synonymized genus, Tylosigma Topsent, 1894 is revived. Thirtysix species were found to be new to science, excluding the first Central West Atlantic record of the genus Halicnemia, not named at the species level…

The biodiversity of black flies (Diptera: Simuliidae), which are biting insects of medical and veterinary importance, is strikingly high in Southeast Asian countries, such as Indonesia, Malaysia, Philippines and Thailand. In 2013, we began to explore the fauna of black flies in Vietnam, which has so far been poorly studied. In this monograph, the wealth of the biodiversity of black flies in Vietnam is also confirmed on the basis of the results of our recent investigations, though limited to five provinces in the country. Morphotaxonomic studies of black flies obtained from Sapa, Lao Cai Province, northern Vietnam, in 2014 and Nghe An Province, northern Vietnam, in 2015, and reexaminations of black flies collected from Tam Dao, Vinh Phuc Province, northern Vietnam, in 2013, Thua Thien Hue Province, central Vietnam, in 2014, and Lam Dong Province, southern Vietnam, in 2014, were conducted. A total of 22 species are described as new, including one in the newly recorded subgenus Montisimulium Rubtsov, and three species are recognized as new records from Vietnam. This investigation…

The taxonomy and systematics of the genus Digitonthophagus Balthasar (Coleoptera: Scarabaeidae: Scarabaeinae: Onthophagini) is revised. A detailed study of the male genitalia combined with external morphology suggests that the variability, previously recognized, for D. gazella is hiding a species complex within the Afrotropical region and the Arabian Peninsula. The current study recognizes 16 species; 13 from the Afrotropical region and Arabian Peninsula and three from the eastern portion of the Saharo-Arabian region and the continental Indomalayan region. Species are organized into six species groups based on the results of the morphology-based phylogenetic analysis. The following 12 species are described as new: D. aksumensis Génier new species; D. biflagellatus Génier new species; D. dilatatus Génier new species; D. eucatta Génier new species; D. falciger Génier new species; D. fimator Génier new species; D. namaquensis Génier new species; D. petilus Génier new species; D. sahelicus Moretto new species; D. uks Génier new species; D. ulcerosus Génier new species; and D.…

A taxonomic revision of the subgenus Chthonius (Ephippiochthonius) in the Iberian Peninsula, Balearic Islands and Macaronesia is presented. New and previously insufficiently studied characteristics are shown to be taxonomically useful, such as the chelal lyrifissures patterns, chaetotaxy and condylar complex. Three taxa previously treated as subgenera of Chthonius are here raised to generic rank: Ephippiochthonius n. stat., Globochthonius n. stat., and Hesperochthonius n. stat. Two new genera are described: Cantabrochthonius n. gen. and Occidenchthonius n. gen. Thirty-five new species are described: Ephippiochthonius aini n. sp., E. andalucia n. sp., E. aurouxi n. sp., E. benimaquia n. sp., E. caceresi n. sp., E. castellonensis n. sp., E. comasi n. sp., E. fadriquei n. sp., E. galcerani n. sp., E. gonzalezi n. sp., E. henderickxi n. sp., E. ibiza n. sp., E. masoae n. sp., E. portugalensis n. sp., E. riberai n. sp., E. serengei n. sp., E. sevai n. sp., E. tarraconensis n. sp., E. vicenae n. sp., E. zaballosi n. sp., Occidenchthonius anae n. sp., O. beieri n. sp., O. ebo n. sp., O.…

A re-evaluation of the phylogenetic relationships of the four species of the monophyletic Cyrtodactylus conodorensis group using the mitochondrial gene ND2 with Bayesian and Maximum Likelihood analyses provides strong statistical support for the recovery the cave-adapted ecomorphs C. eisenmanae and C. grismeri as the sister lineage to the scansorial forest-adapted ecomorphs C. condorensis and C. leegrismeri. This phylogeny provides the context in which these ecomorphs are morphologically characterized. The majority of newly described species within Cyrtodactylus have come from karst habitats and granite boulder cave-like microhabitats. Although some authors have commented on subtle to notable differences in the morphology and color pattern associated with species from these habitats, none have explicitly presented data necessary to characterize this putative departure from a more generalized, scansorial morphology. To this end, the closely related species of the condorensis group are used to provide a suggested protocol to recover and delimit characters adaptive to a restrictive…

The large spiny mouse Neacomys spinosus (Thomas, 1882) has been considered the widest ranging species of the genus, occurring in southern Colombia, eastern Peru, western Brazil and northern Bolivia. The morphological variation between subspecies and populations of N. spinosus has been noted; nonetheless, this variation has not been assessed in a morphological or molecular context. Here, we present a taxonomic revision of Neacomys spinosus s.l. using qualitative and quantitative morphological analyses. These analyses were complemented with molecular analysis to reconstruct the phylogenetic relationships among species of Neacomys, based on sequences of the cytochrome b gene. Our results reveal that N. spinosus s.l. is a monophyletic group, and morphological and molecular evidence to differentiate three taxa: N. spinosus s.s., an endemic species from mountain cloud forests in Peru; N. amoenus s.l. from the Cerrado between Bolivia and Brazil to the Amazonia between Ecuador and northern Peru, and Neacomys sp. nov. from mountain cloud forests from southern Peru to Bolivia. Also, our…

The Asian frog genus Megophrys is a diverse group of morphologically conserved, forest-dwelling frogs. The genus harbours highly localised species diversification and new species continue to be described on a regular basis. We examined the taxonomic status of a population of Megophrys frogs from the Hoang Lien Range in northern Vietnam and southern China previously identified as M. kuatunensis (subgenus Panophrys). Preliminary phylogenetic analyses using a fragment of 16S rDNA places the species in question within the Megophrys (subgenus Panophrys) species group, a primarily Chinese radiation within the genus. On the basis of morphological, molecular and bioacoustic data, we conclude that this population does not represent M. kuatunensis, or any known species in the genus. We herein describe this species of Megophrys as new. Known only from Sa Pa District, Lao Cai Province in Vietnam and Jinping County, Yunnan Province in China, the new species is likely to be threatened by ongoing deforestation in the region. We provide an updated species description of M. kuatunensis based on type…

Fossil butterflies are extremely rare. Yet, they are the only direct evidence of the first appearance of particular characters and as such, they are crucial for calibrating a molecular clock, from which divergence ages are estimated. In turn, these estimates, in combination with paleogeographic information, are most important in paleobiogeographic considerations. The key issue here is the correct allocation of fossils on the phylogenetic tree from which the molecular clock is calibrated.The allocation of a fossil on a tree should be based on an apomorphic character found in a tree based on extant species, similar to the allocation of a new extant species. In practice, the latter is not done, at least not explicitly, on the basis of apomorphy, but rather on overall similarity or on a phylogenetic analysis, which is not possible for most butterfly fossils since they usually are very fragmentary. Characters most often preserved are in the venation of the wings. Therefore, special attention is given to possible apomorphies in venational characters in extant butterflies. For estimation…

A revision of the cis-andean species of Brycon, with the exception of the Brycon pesu species-complex, is presented. Twenty-one Brycon species (including B. pesu) are recognized from cis-andean river systems: Brycon stolzmanni Steindachner, from the upper Río Marañon basin, Peru; Brycon coxeyi Fowler, from the Río Marañon basin, Ecuador and Peru; Brycon polylepis Moscó Morales, from the Lago de Maracaibo, Río Orinoco, upper rio Amazonas, and rio Tocantins basins, Venezuela, Colombia, Peru, and Brazil; Brycon coquenani Steindachner, from the upper Río Caroni, Río Orinoco basin, Venezuela; Brycon insignis Steindachner, from the rio Paraíba do Sul and small adjacent coastal river basins of eastern Brazil; Brycon vermelha Lima & Castro, endemic from the rio Mucuri basin, eastern Brazil; Brycon howesi new species, endemic from the rio Jequitinhonha basin, Brazil; Brycon dulcis new species, endemic from the rio Doce basin, eastern Brazil; Brycon ferox Steindachner, from several small coastal river systems, including the rio Mucuri basin in eastern Brazil; Brycon vonoi new species, from…

The taxonomy of aeolidacean nudibranchs of the traditional group previously known as Tergipedidae is discussed. To integrate the diverse molecular phylogenetic pattern and morphological disparity in a broadly ontogenetic context a revised classification at the family level is presented. The families Calmidae Iredale & O'Donoghue, 1923, Eubranchidae Odhner, 1934, Fionidae Gray, 1857 s. str. (restricted, with the genus Fiona only), and Tergipedidae Bergh, 1889 s.str. (restricted, with inclusion of the genus Tergipes only) are restored. The families Cuthonidae Odhner, 1934 s.str. (restricted, with only single genus Cuthona), Cuthonellidae Miller, 1971, stat. nov., and Trinchesiidae Nordsieck, 1972 (with inclusion of the genera Catriona, Diaphoreolis, Phestilla, Tenellia, Trinchesia) are reinstated. At the genus level, the family Trinchesiidae appears as a most diverse assemblage that needs to be further divided. In the present study, the “Eolis” pustulata species complex is particularly investigated, including description of a new ontogenetically different species Zelentia ninel sp.…

The taxonomy of species within the genus Unio (Bivalvia: Unionidae: Unioninae) in Russia and Ukraine has been contentious due to the lack of correspondence between three concurrent yet divergent classifications. In order to clarify which classification system best reflects the evolutionary relationships among these taxa, we performed detailed morphological analyses on 720 Ukrainian and Russian specimens, complemented with molecular data (COI) from a selected number of specimens. The morphological character data set shows the existence of only three widespread species with slight eco-morphological variations. Statistical analyses of shell morphometric parameters and molecular analyses based on mtDNA COI gene fragment sequences confirm the existence of the same three species within a single genus, Unio, in Russia and Ukraine, that is U. pictorum, U. tumidus and U. crassus. Results from molecular analyses suggest the existence of an additional subgroup within the U. crassus lineage, U. crassus cf. courtilieri that deserves further research. The present integrated approach confirms the…

This is the first part of the revision of the Alycaeidae of China, Laos and Vietnam. Here we revise the species hitherto classified in Chamalycaeus Möllendorff, 1897 (genera Dicharax and Metalycaeus in this study). We show that no Chamalycaeus live in the region, and the alycaeid species of the investigated region can be classified into five genera: Alycaeus Baird, 1850, Dicharax Kobelt & Möllendorff, 1900, Dioryx Benson, 1859, Metalycaeus Pilsbry, 1900 and Pincerna Preston, 1907. We propose Dioryx dautzenbergi Páll-Gergely nom. nov. as a replacement name for Alycaeus (Dioryx) major Bavay & Dautzenberg, 1900, non Alycæus (Dioryx) granum var. major Godwin-Austen, 1893. Alycaeus anceyi Mabille, 1887, A. eydouxi Venmans, 1956, A. mouhoti L. Pfeiffer, 1862, A. rolfbrandti Maassen, 2006 and A. vanbuensis Bavay & Dautzenberg, 1900 are retained in Alycaeus. Alycaeus costulosa Bavay & Dautzenberg, 1912 and A. maolanensis Luo, Zhang & Zhuo 2009 were transferred to Pincerna. We examined newly collected specimens and the type specimens of all species with the exception of the following: A.…

An extensive taxonomic revision of Gymnura micrura based on external and internal morphology, and considering specimens from its entire geographical distribution in the Atlantic Ocean, is presented. Gymnura micrura is redescribed and a neotype is designated; its distributional range is limited to the Southwestern Atlantic. Two new species of butterfly rays are described: Gymnura lessae, sp. nov., occurring in the North and Central Western Atlantic, and Gymnura sereti, sp. nov., found in the Eastern Central Atlantic. The three species are morphologically very similar (with G. micrura most similar to G. lessae, sp. nov.) and cannot be distinguished based on the primary diagnostic characters typically utilized for butterfly rays. The dorsal color, smaller size and eventual presence of a dorsal fin in some males may be helpful to distinguish G. micrura, whereas the size and morphology of the clasper are the main external characters separating G. sereti, sp. nov., from the other two species, although the shape of disc (especially among adult males) and contour of the lower lip are also…

Botryllus schlosseri is a widespread colonial ascidian commonly considered cosmopolitan and amply used as model for researches ranging from developmental biology to immunobiology. Recently, molecular data lead to hypothesize that the species named B. schlosseri may consist of more than a single taxon. Indeed, five highly divergent clades, named A-E, have been genetically identified and are referred as cryptic species. In this context, and lacking both a type and a detailed morphological description, we believe that it is necessary, as a taxonomic reference point, to designate a neotype and re-describe the species. Therefore, a sample from the Lagoon of Venice (Adriatic Sea, Italy) was deposited as neotype in the Natural History Museum of Venice (Italy), preserved both in formalin and in 90% ethanol. Here we provide a morphological description of the suggested neotype of B. schlosseri that takes into account several developmental stages (oozooid, zooid of first blastogenic generations, and mature zooid) and is carefully compared with the previous descriptions of samples coming from…

Thirty-four species of Culicidae are present in the UK, of which 15 have been implicated as potential vectors of arthropod-borne viruses such as West Nile virus. Identification of mosquito feeding preferences is paramount to the understanding of vector-host-pathogen interactions which, in turn, would assist in the control of disease outbreaks. Results are presented on the application of DNA barcoding for vertebrate species identification in blood-fed female mosquitoes in rural locations. Blood-fed females (n = 134) were collected in southern England from rural sites and identified based on morphological criteria. Blood meals from 59 specimens (44%) were identified as feeding on eight hosts: European rabbit, cow, human, barn swallow, dog, great tit, magpie and blackbird. Analysis of the cytochrome c oxidase subunit I mtDNA barcoding region and the internal transcribed spacer 2 rDNA region of the specimens morphologically identified as Anopheles maculipennis s.l. revealed the presence of An. atroparvus and An. messeae. A similar analysis of specimens morphologically identified as…

Meadow vipers (Vipera ursinii-renardi complex) are small-bodied snakes that live in either lowland grasslands or montane subalpine-alpine meadows spanning a distribution from France to western China. This complex has previously been the focus of several taxonomic studies which were based mainly on morphological, allozyme or immunological characters and did not clearly resolve the relationships between the various taxa. Recent mitochondrial DNA analyses found unexpected relationships within the complex which had taxonomical consequences for the detected lineages. The most surprising was the basal phylogenetic position of Vipera ursinii graeca, a taxon described almost 30 years ago from the mountains of Greece. We present here new analyses of three nuclear markers (BDNF, NT3, PRLR; a first for studies of meadow and steppe vipers) as well as analyses of newly obtained mitochondrial DNA sequences (CYT B, ND4).Our Bayesian analyses of nuclear sequences are concordant with previous studies of mitochondrial DNA, in that the phylogenetic position of the graeca clade is a clearly…

An annotated and photographically illustrated checklist with DNA barcodes of the species of bony fishes collected during a month-long research cruise of the Spanish Research vessel B/O Miguel Oliver is presented. The vessel made trawls on the continental shelf of the Pacific coast of Central America, in November-December 2010, at depths of 108-1625 m. This list, based on 707 specimens (of a total of 876 specimens collected during the whole expedition), includes 129 species belonging to 15 orders, 61 families, and 97 genera. New information is presented on the geographical distributions of more than a third of those species, with 29 species (22.4%) representing new records from Central American waters and 17 species (13.2%) having expanded latitudinal ranges. Data on capture depths demonstrate increased depth ranges due to new minimum and/or maximum known depths for 31 species, i.e. 24% of those captured. Tissue samples from frozen specimens were used to obtain DNA barcodes of 682 (96.5%) individuals belonging to 118 species (91.4% of those recorded here), which have been made…

The Dichotomius sericeus species group of the subgenus Luederwaldtinia is reviewed. This group comprises eight species endemic to the South American Atlantic forests, Caatinga and associated areas of Brazil, Paraguay and Argentina: Dichotomius sericeus (Harold, 1867); Dichotomius irinus (Harold, 1867); Dichotomius laevicollis (Felsche, 1901); Dichotomius schiffleri Vaz-de-Mello, Gavino Louzada, 2001; Dichotomius guaribensis sp. nov.; Dichotomius gilletti sp. nov; Dichotomius iannuzziae sp. nov; and Dichotomius catimbau sp. nov. Lectotypes are designated for D. sericeus (Harold, 1867), D. irinus (Harold, 1867), D. laevicollis (Felsche, 1901) and D.sericeus var. aterrimus (Luederwaldt, 1929) [here synonymized with D. sericeus]. In this revision each species is analyzed as follows: a detailed literature review, a diagnosis, description, illustrations of key morphological characters, list of material examined and a geographic distribution.

A checklist of longhorn beetles (Coleoptera: Cerambycidae) within the present geographical frontier of Indian subcontinent up to 2016 is provided. As per the current checklist prepared, there are 1536 species, classified under 440 genera, 72 tribes, and seven subfamilies of Cerambycidae (Parandrinae is not present in India). The report is accounted for 4.2 per cent of species, 7.94 per cent of genera and 28.24 per cent of tribes from India as compared to global record. For each species, accepted nomenclature followed by all relevant works reporting systematics, distribution and ecology of Indian longhorn beetles is provided along with synonyms, type locality and distribution within and outside India.

Abelisaurid theropods were most abundant in the Gondwana during the Cretaceous Period. Pycnonemosaurus nevesi Kellner & Campos, 2002 was the first abelisaurid dinosaur described from the Bauru Group (Brazil, Upper Cretaceous). Nevertheless, its initial description was based on the comparison of a restricted number of remains with other abelisaurids. In this paper, I present a new description of the morphology of Pycnonemosaurus nevesi, including three new caudal transverse processes and a discussion of several new characteristics based on perspectives derived from recently described abelisauroids. Pycnonemosaurus nevesi differs from other abelisaurids based on the following features: a pubis with a small rounded foot and a ventrally-bowed anterior distal end; posterior caudal vertebrae with a hook-shaped transverse process that has an anterodistal expansion that is short and bowed; a strong and massive tibia with a well-developed lateral malleolus that is ventrally expanded. The unfused sutures represent signs of skeletal immaturity, but the specific ontogenetic stage is still…

A new species, Xenophrys insularis sp. nov., is described based on a series of specimens collected from Nan’ao Island, Shantou City, Guangdong Province, China. The new species is a separately evolving lineage that was robustly supported by the phylogenetic analysis based on the mitochondrial CO1 + 12S rRNA + 16S rRNA genes; morphologically, it can be distinguished from other known congeners by the following combination of characteristics: body size moderate, SVL 38.6–41.2 mm in adult males, 47.1 mm in a single adult female; snout obtusely rounded in dorsal view; head width slightly larger than head length; strong vomerine ridge bearing vomerine teeth; margin of tongue weakly notched behind; supratympanic fold forming a large swollen supraaxillary gland above insertion of arm; hindlimbs relatively short, heels not meeting when thighs are held at right angles to body, tibio-tarsal articulation reaches forward the posterior edge of tympanum; fingers and toes without lateral fringes, with rudiment of web at bases of toes, distinct subarticular tubercle only at the base of each finger…

Heteropriapulus Kritsky, 2007 (Monogenea: Dactylogyridae), which originally included only two species from the gills of loricariid catfishes, is reviewed and six newly described species from loricariids in the Paraná River basin in Brazil are added. Diagnosis of the genus is amended and a key to the species identification is provided. Heteropriapulus anchoradiatus n. sp. from Pterygoplichthys ambrosettii (Holmberg) (Hypostominae) differs from its congeners by having a long sclerotized vagina, ventral anchors with short shaft and conspicuous superficial root, and a conspicuous and robust postero-medial process on the dorsal bar; H. bitomus n. sp. from the same fish host differs by the presence of two pairs of sclerotized patches associated with the ventral anchors; H. falxus n. sp. from Hypostomus strigaticeps (Regan) (Hypostominae) and Hypostomus ancistroides (Ihering) (Hypostominae) is unique by the shape of the accessory piece composed of two strongly sclerotized subunits; H. microcleithrus n. sp. from P. ambrosettii differs by presenting the smallest length of the dorsal bar and…

The banded knife fish Gymnotus carapo is among the most widely distributed, broadly adapted (eurytopic), and phenotypically variable fish species in South America, with a geographic range of about 14 million km2, from the Llanos of Venezuela to the Pampas of northern Argentina. Here we assess the structure of phenotypic variation in G. carapo across this vast range from a study of 486 specimens representing the G. carapo clade, including 175 specimens of G. carapo collected from across the continental platform. We use multivariate statistics to quantify phenotypic differences within and among subspecies and species in aspects of pigmentation, caliper-based morphometrics, geometric morphometrics, meristics, and osteology. Our results demonstrate significant, but not diagnostic, differences among specimens representing seven new subspecies: G. c. australis from the La Plata (Paraná-Paraguay) basin, G. c. caatingaensis from the Parnaíba basin in the Brazilian state of Piauí, G. c. carapo from Suriname and French Guiana, G. c. madeirensis from the upper Madeira basin, G. c. occidentalis…

We describe Notocomplana hagiyai sp. nov. from Ishikari Bay, Hokkaido, northern Japan. Notocomplana hagiyai sp. nov. is characterized by i) a larger prostatic vesicle relative to the seminal vesicle and ii) a Lang’s duct that is shorter than the long axis of Lang’s vesicle. Melloplana japonica (Kato, 1937) is transferred to the genus Notocomplana Faubel, 1983 based on the structure of its prostatic vesicle, and we record the finding of N. koreana (Kato, 1937) and N. septentrionalis (Kato, 1937) in western Hokkaido. A pair of new cytochrome c oxidase subunit I (COI) primers was designed to infer the phylogeny among the four species, and we concluded that COI is more informative than 16S rRNA for barcoding polyclad flatworms.

The Granulate Ambrosia Beetle Xylosandrus crassiusculus, an alien species of Asian origin, was recorded for first time in the Iberian Peninsula. Many specimens were collected in October 2016 in the Valencia region (Spain) from infested carob trees. The species is included in the EPPO Alert List as causing serious damage in many Mediterranean regions. A key for the morphological identification of the Xylosandrus species occurring in Europe is also reported.

At risk of committing entomological heresy, we question the identity of a dung-burying beetle species that originates from Africa and has been introduced first into Hawaii and subsequently to Australasia, North America, and South America (Fincher 1986; Edwards 2007; Noriega et al. 2010) for pasture improvement and biological control of dung-breeding flies (Waterhouse 1974; Bornemissza 1979). Under the name Onthophagus gazella (Fabricius 1787), it was the first species selected for introduction into Australia by the CSIRO Dung Beetle Project (Bornemissza 1976; Edwards 2007). Firstly, in 1968, a "tropical strain" was introduced from Hawaii where it had become established after introduction from Zimbabwe in 1957 (Markin & Yoshioka 1998). Later, after establishment of the CSIRO Dung Beetle Research Unit in Pretoria in 1970, a "cold" or "even rainfall strain" was introduced into Australia directly from South Africa (Bornemissza 1976) (even rainfall region = south coast of Eastern Cape). The species was subsequently introduced into the southern continental United States of America…

This paper provides the first comprehensive annotated and illustrated inventory of Nudipleura from Mozambique. A total of 267 species are recorded, including 61 putative new species, documented over a period of seven years from several localities along the coast. At least 20 species need further investigation through molecular and taxomic analysis. Of the 186 confirmed described species, 118 are new records for the Mozambican fauna. Sampling was carried in tidal reefs and depths up to 60m on the subtropical and tropical coast of Mozambique. The most representative families were Chromodorididae (69 species), Discodorididae (30 species), Facelinidae (23 species) and Phyllididae (16 species). Nevertheless, a vast area of Mozambique remains unexplored, thus it is likely that the species documented here represent only a fraction of the true Nudipleura diversity of the country.

The generic nomenclature of the hummingbirds is unusually complicated. McGuire et al.'s (2014) recent phylogeny of the Trochilidae based on DNA sequence data has greatly clarified relationships within the family but conflicts strongly with the traditional classification of the family at the genus level, especially that of the largest and most recently derived clade, the Trochilini or "emeralds". We recently presented a historical review of this classification and the generic modifications required by the Code of the International Commission on Zoological Nomenclature. Herein we present a revised generic classification of the Trochilini based upon McGuire et al.'s genetic data, while producing diagnosable generic groupings and preserving nomenclatural stability insofar as possible. However, this generic rearrangement has necessitated the resurrection of nine generic names currently considered synonyms, the synonymization of seven currently recognized genera and the creation of one new genus. The generic changes we recommend to the classification are drastic, and we summarize these in…

The Rufescent Burrowing Frog, Fejervarya rufescens, is thought to have a wide distribution across the Western Ghats in Peninsular India. This locally abundant but secretive species has a short breeding period, making it a challenging subject for field studies. We sampled 16 populations of frogs morphologically similar to F. rufescens in order to understand the variation among populations found across the Western Ghats. Our study shows significant morphological and genetic differences among the sampled populations, suggesting that F. 'rufescens' is a complex of several undescribed species. Using evidence from morphology and genetics, we confirm the presence of five distinct species in this group and formally describe four as new. The new species were delineated using a phylogeny based on three mitochondrial genes (16S, COI and Cytb) and a haplotype network of a nuclear gene (Rag1). Hereafter, the distribution of F. rufescens is restricted to the state of Karnataka and adjoining regions of northern Kerala. Three new species (Fejervarya kadar sp. nov., Fejervarya manoharani sp. nov.…

A new species of the genus Microhyla is described from Jamun Khadi, Jhapa district of eastern Nepal, based on molecular and morphological comparisons. This species is the sister taxon of Microhyla ornata and can be distinguished by a unique vocalization, morphology and molecular phylogeny. The uncorrected genetic divergences based on rRNA gene between the new species and its closest congeners, M. nilphamariensis, M. ornata and M. rubra were 5.34%, 6.67%, and 8.31%, respectively. The new species, Microhyla taraiensis sp. nov., is distinguished from each other of Microhyla by a combination of the following morphological characters: (1) relatively larger body size (SVL ranges 19.9-20.3 mm, n = 4 in the males and 22.1-24.9 mm, n = 3 in the females); (2) dorsal surface of head and body with light red dots; (3) toes webbing poorly developed or absent; (4) a large round inner metacarpal tubercle; and an (5) elongated outer metacarpal tubercle. In addition, our study also provides a new record of Microhyla nilphamariensis from Nepal.

Isotrias penedana Trematerra, 2013 was described from north Portugal based on males alone. Unidentified females were associated with the males using DNA barcoding, revealing sexual dimorphism in the species. Males and females differ in forewing shape, markings, and size, with females significantly smaller than males. The female is described and illustrated for the first time. We also document the species' occurrence in northern Spain.

Eight species are recognised in the Aphanius dispar group. Aphanius dispar from the Red and Mediterranean Sea basins, A. stoliczkanus from coastal areas of the Arabian/Persian Gulf, the northern Arabian Sea east to Gujarat in India, the Gulf of Oman and some endorheic basins in Iran and Pakistan, A. richardsoni from springs in the Dead Sea basin in Jordan and Israel, A. sirhani from the Azraq Oasis in Jordan, A. ginaonis from one spring in Iran, A. furcatus from few streams and springs in Iran and A. stiassnyae from one lake in Ethiopia. Aphanius kruppi, new species, from the Wadi al Batha drainage in northern Oman, is distinguished from adjacent A. stoliczkanus by having 9-14 brown or grey lateral bars on the flank in the male, a roundish, diamond-shaped or somewhat vertically-elongate blotch centred on the caudal-fin base in the female and 2-3 scale rows on the caudal-fin base. The available molecular genetic data for A. dispar reject the hypothesis of the presence of a single widespread coastal species in the Middle East and make it likely that two additional unidentified species…

The Heteroptera (Hemiptera) of Argentina are catalogued. A total of 686 genera and 2030 species are listed together with their synonyms. References are given to the original descriptions and the subsequent taxonomic position, and the geographic distribution is included.

The orbiniid polychaetes chiefly from Antarctic and subantarctic seas and off South America are described based on collections of the National Museum of Natural History and new material from surveys conducted by the United States Antarctic Program and other federal and privately funded sources as well as participation in international programs. A total of 44 species of Orbiniidae distributed in 10 genera are reported from the Pacific Ocean and waters off South America and Antarctica. Twenty-one species are new to science; one species is renamed. Berkeleyia heroae n. sp., B. abyssala n. sp., B. weddellia n. sp.; B. hadala n. sp., Leitoscoloplos simplex n. sp., L. plataensis n. sp., L. nasus n. sp., L. eltaninae n. sp., L. phyllobranchus n. sp., L. rankini n. sp., Scoloplos bathytatus n. sp., S. suroestense n. sp., Leodamas hyphalos n. sp., L. maciolekae n. sp., L. perissobranchiatus n. sp., Califia bilamellata n. sp., Orbinia orensanzi n. sp., Naineris antarctica n. sp., N. argentiniensis n. sp., Orbiniella spinosa n. sp., and O. landrumae n. sp. are new to science. A new name,…

Species of eight species-groups (seven named and one unnamed) of Simulium (Simulium) Latreille are revised chiefly based on the adult female and male genitalia. Four species-groups are each divided into more than two groups. Thus, the S. christophersi species-group is divided into two (S. christophersi and S. nebulicola species-groups), the S. griseifrons species-group into six (S. griseifrons, S. grossifilum, S. chungi, S. crocinum, S. indicum and S. yadongense species-groups), the S. malyschevi species-group into two (S. malyschevi and S. pavlovskii species-groups), and the S. melanopus species-group into three (S. melanopus, S. dumogaense and S. iridescens species-groups). The S. crassifilum species-group is merged with the S. variegatum species-group. Simulium fulvipes (Ono) of the former S. malyschevi species-group and S. dentastylum Yang, Chen & Luo of Simulium s. str. species unplaced to species-group are removed from the subgenus Simulium because their male styles are subequal in length to the coxites. A revised classification of species of the 15 species-groups including…

A taxonomic revision of the Cardiocondyla nuda species group is presented based on methods of Numeric Morphology-Based Alpha-Taxonomy (NUMOBAT) and supplemented by analysis of mtDNA. A total of 258 samples with 571 worker individuals were investigated by the hierarchical and non-hierarchical exploratory data analyses NC-Ward and NC-K-Means clustering considering 16 NUMOBAT characters. Two species are described as new, increasing the number of species in the group to eight. We separate the group into two main clades: the C. mauritanica species complex, which is of Oriental and Indo-Australian origin and contains the cryptic species C. mauritanica Forel 1890, C. strigifrons Viehmeyer 1922, C. kagutsuchi Terayama 1999, and C. itsukii sp. nov. and the Australasian and Polynesian C. nuda species complex with the cryptic species C. nuda (Mayr 1866), C. atalanta Forel 1915, C. paranuda Seifert 2003, and C. compressa sp. nov. The mean error of the two NC-clustering methods relative to the controlling linear discriminant analysis was 0.4% in C. mauritanica, 2.2% in C. itsukii, 0% in C.…

We present the complete mitochondrial (mt) genome sequence of the stonefly, Styloperla spinicercia Wu, 1935 (Plecoptera: Styloperlidae), the type species of the genus Styloperla and the first complete mt genome for the family Styloperlidae. The genome is circular, 16,129 base pairs long, has an A+T content of 70.7%, and contains 37 genes including the large and small ribosomal RNA (rRNA) subunits, 13 protein coding genes (PCGs), 22 tRNA genes and a large non-coding region (CR). All of the PCGs use the standard initiation codon ATN except ND1 and ND5, which start with TTG and GTG. Twelve of the PCGs stop with conventional terminal codons TAA and TAG, except ND5 which shows an incomplete terminator signal T. All tRNAs have the classic clover-leaf structures with the dihydrouridine (DHU) arm of tRNASer(AGN) forming a simple loop. Secondary structures of the two ribosomal RNAs are presented with reference to previous models. The structural elements and the variable numbers of tandem repeats are described within the control region. Phylogenetic analyses using both Bayesian (BI) and…

The confused taxonomy of the east Palaearctic pear psyllids, serious pests on cultivated pear, is reviewed. Fifty-six nominal species have been reported from Pyrus, 25 of which we consider valid and ten as not being associated with Pyrus. Our taxonomic revision suggests that, in Korea, four Cacopsylla species develop on pear: the univoltine C. burckhardti Luo et al. previously misidentified as C. pyrisuga (Foerster), the polyvoltine, seasonally dimorphic C. jukyungi (Kwon) (winter form 'cinereosignata' Luo et al., summer form 'jukyungi'), commonly found in Korean pear orchards, and C. maculatili Li (winter form 'maculatili', summer form 'qiuzili' Li) previously misidentified as C. pyricola (Foerster) by some authors, as well as the probably polyvoltine but not dimorphic C. sandolbaea (Park & Lee). The former three species (C. burckhardti, C. jukyungi, misidentified as C. chinensis (Yang & Li), and C. maculatili) occur also in Japan. Keys to the adult and fifth instar immatures as well as short biological notes are provided, and C. jukyungi and C. sandolbaea are redescribed.…

We describe a new species of megophryid frog from Maoershan Nature Reserve in southern China. Leptolalax maoershanensis sp. nov. is distinguished from its congeners by a combination of the following morphological characters: medium size (SVL 25.2–30.4 mm in eight adult males and 29.1 mm in one adult female); head longer than wide; externally distinct tympanum; distinct black supratympanic line present; dorsal skin shagreened with small tubercles and longitudinal folds; distinct dark spots on the flank; creamy-white chest and belly with irregular black spots; grey-pinkish to dark brownish-violet ventral skin of limbs with numerous whitish speckles; distinct ventrolateral glands forming a white line; finger webbing and fringes absent; toe webbing rudimentary and lateral fringes narrow; longitudinal ridges indistinct under toes and not interrupted at the articulations; and a bicolored iris. The new species differs from all known congeners by an uncorrected p-distance of >6.6% at the 16S rRNA gene fragment examined, and phylogenetic analysis clusters the new species with L. laui and L.…

As First Revisers, we give priority to Aphanius fontinalis over A. altus and A. litoralis and to A. meridionalis over A. parvus. A neotype is designated from Lake Eğirdir for Aphanius iconii. Family groups in the deeply polyphyletic fish family Cyprinodontidae are discussed. Aphaniidae, Cubanichthyidae and Orestiidae are proposed as distinct families, restricting the family Cyprinodontidae to the New World genera Cualac, Cyprinodon, Floridichthys, Jordanella and Megupsilon.

The Nearctic species of Calliphora Robineau-Desvoidy are revised and all species are redescribed and/or diagnosed. Diagnostic characters to permit reliable identification of both sexes of Calliphora aldrichia (Shannon) and C. montana (Shannon) and detailed distributional records for both species are provided for the first time. A lectotype is designated for Calliphora loewi Enderlein, 1903. A revised key to the 13 species of Nearctic Calliphora is also included. The key is based on examination of over 1,000 specimens from across North America and the structure of the terminalia of both sexes of each species. Complete illustrations of the terminalia of both sexes are provided for all species, including those of eight poorly known species: Calliphora alaskensis (Shannon), C. aldrichia (Shannon), C. coloradensis Hough, C. grahami Aldrich, C. latifrons Hough, C. livida Hall, C. montana (Shannon) and C. terraenovae Macquart. The female terminalia of C. alaskensis, C. aldrichia, C. coloradensis, C. livida and C. montana are illustrated for the first time. Barcode data for all 13 species…

Hoverflies are relevant to pollination, predation, phytophagy and decomposition processes and they are also used as bioindicators. The numerous recent advances in the study of Spanish hoverflies and the absence of species lists for the Spanish provinces prompted us to update the national catalogue and fill in the gap at the provincial level. Andorra and Gibraltar are also included in this review. A total of 421 species of 72 genera are included in the present catalogue (417 species in Spain; 86 in Andorra; 43 in Gibraltar). León (182 spp), Salamanca (143 spp), Madrid (134 spp), Ciudad Real (124 spp) and Huesca (121 spp) are the Spanish provinces with the highest numbers of species recorded. The Balearic Islands have 81 species and the Canary Islands 41, with one and 11 endemic species respectively. The richest hoverfly genera in Spain are Cheilosia (56 spp), Merodon (40 spp plus 1 sp from Gibraltar) and Eumerus (38 spp plus 1 sp from Gibraltar), all of them being Eristalinae; within the Syrphinae, Paragus is the richest genus (18 spp). The possibility of elaborating regional…

Three species of the genus Allocosa Banks, 1900 from southern South America are redescribed: Allocosa alticeps (Mello-Leitão, 1944), A. brasiliensis (Petrunkevitch, 1910) and A. senex (Mello-Leitão, 1945). The female of A. senex is described for the first time and the species is revalidated. A new species, A. marindia sp. nov. from southern Uruguay and southern Brazil is described. The new species is distinguished by the flattened terminal apophysis of the male bulb and the conspicuous pointed projections on the posterior margin of the female epigynum. The species inhabits in sandy estuarine and oceanic coasts with psammophile vegetation.

Potamotrygon scobina Garman, 1913, described from Cametá, rio Tocantins, lower Amazon basin, is taxonomically reviewed through an extensive morphological study of internal and external features. Specimens identified as P. scobina from different locations of the Amazon basin were also studied. The identity of P. scobina, its morphology, and distribution are redefined. In addition, three new species closely related to P. scobina are described from Brazil: Potamotrygon adamastor, sp. nov., from rio Uraricoera, rio Branco system, upper Amazon basin; Potamotrygon amazona, sp. nov., from rio Juruá, upper Amazon basin; and Potamotrygon garmani, sp. nov., from the mid to upper rio Tocantins. These three new species do not occur sympatrically with P. scobina, as far as known. Together with P. scobina and P. limai Fontenelle, Silva & Carvalho, 2014, the new species have three angular cartilages of different sizes, a condition not seen in any other potamotrygonin (which have either one or two angulars). Diagnostic characters in combination are primarily morphometric proportions, especially…

The Atlantic Rainforest is a hotspot of biodiversity, housing several endemic species. Environmental stasis through broad time scales, vast latitudinal extension and landscape heterogeneity are thought to contribute in explaining the greater species richness of this biome. Unfortunately, it is threatened mainly due to anthropic-driven habitat loss. Ectotherms of low-mobility, such as tropical, small soft-bodied railroad-worms, may be especially threatened by anthropogenic climate changes. Many of such species have narrow climatic niches and therefore might become extinct before we know them. Here we describe a new genus endemic of the Atlantic Rainforest mountain ranges, and five spatially disjunct new species. Akamboja gen. nov. is unique by its ten-segmented antenna, IV to VIII with two short symmetrical branches, branches of antennomere IX fused in a singular flabellum, slightly depressed medially; elytron short, surpassing the second to fourth abdominal segment (depending on species); first tarsomere of anterior leg with a ventral comb; claws with six long and asymmetrical…

We describe a new, medium-sized Leptolalax species from north central Vietnam. Leptolalax puhoatensis sp. nov. is distinguished from its congeners by a combination of having a body size range of 24.2-28.1 mm in eight adult males and 27.3-31.5 mm in three adult females; distinct dorsolateral markings including blackish spots on the flank and dark canthal and/or temporal streaks; males with a reddish-brown venter, often with faint white dusting and females with a pale pink venter; skin on dorsum with tiny, indistinct, low tubercles in preservative, more distinct and forming low dorsal ridges on dorsal surface in life; toes with webbing basal and narrow lateral fringes; iris copper in upper half and golden in lower half; and a call consisting of a single note and a dominant frequency of 4.9-5.6 kHz (at 22.3-25.8º C). Uncorrected sequence divergences between L. puhoatensis sp. nov. and all homologous 16S rRNA sequences available for known species in the genus are ≥6.3%.

A phylogenetic study of the Loricariidae with emphasis on the Neoplecostominae is presented based on a maximum parsimony analysis of 268 phenotypic characters encompassing osteology, arthrology, and external morphology. Results support previous hypotheses of the monophyly of the Neoplecostominae and each of the included genera: Hirtella, Isbrueckerichthys, Kronichthys, Neoplecostomus, Pareiorhaphis, and Pareiorhina. In addition, previously undiscovered diversity was revealed within the subfamily as an additional genus-level taxon, herein described as Euryochus. Relationships among neoplecostomine genera are: (Kronichthys (Euryochus ((Hirtella + Pareiorhaphis) (Pareiorhina (Isbrueckerichthys + Neoplecostomus))))). Additional undescribed diversity was also detected among most neoplecostomine genera and the Hypoptopomatinae. In addition, recently discovered genera Nannoplecostomus and Microplecostomus were included in the analysis, and were identified as sequential sister-taxa to Neoplecostominae + Hypoptopomatinae, which are currently not included in any subfamily and regarded as…

Brachycephalus is a frog genus endemic to the Brazilian Atlantic Forest and characterized by the bright yellow-orange aposematic colors and the high degree of miniaturization. Herein, we describe a new species of Brachycephalus from Serra do Brigadeiro, Municipality of Ervália, Minas Gerais State, southeastern Brazil. Specimens were collected at high altitudes (i.e., 1266-1498 m above sea level) amidst the leaf litter. The new species is characterized by the presence of black connective tissue covering all dorsal muscles, body completely yellow-orange in life, presence of skull and post-cranial plates, large size (SVL of adults: 14.8-18.5 mm), bufoniform body, absence of metacarpal and metatarsal tubercles, and presence of harmonics in its advertisement call.

Sturnira is the most speciose genus of New World leaf-nosed bats (Phyllostomidae). We name Sturnira adrianae, new species. This taxon is born polytypic, divided into a larger subspecies (S. a. adrianae) widespread in the mountains of northern and western Venezuela, and northern Colombia, and a smaller subspecies (S. a. caripana) endemic to the mountains of northeastern Venezuela. The new species inhabits evergreen, deciduous, and cloud forests at mainly medium (1000-2000 m) elevations. It has long been confused with S. ludovici, but it is more closely related to S. oporaphilum. It can be distinguished from other species of Sturnira by genetic data, and based on discrete and continuously varying characters. Within the genus, the new species belongs to a clade that also includes S. oporaphilum, S. ludovici, S. hondurensis, and S. burtonlimi. The larger new subspecies is the largest member of this clade. The two new subspecies are the most sexually dimorphic members of this clade. The smaller new subspecies is restricted to small mountain systems undergoing severe deforestation…

Nine species of Marphysa from the Grand Caribbean Region are recognized and described based on the type and non-type specimens. One species is formally described as new: M. emiliae n. sp., and one is re-established as a valid species: M. fragilis Treadwell, 1911. The diagnosis of Nicidion Kinberg, 1865 is restricted based on novel features of the maxillary apparatus. Nicidion angeli (Carrera-Parra & Salazar-Vallejo, 1998) is redescribed, and two species that previously belonged to Marphysa, are transferred to Nicidion: N. longula (Ehlers, 1887) n. comb. and N. obtusa (Verrill, 1900) n. comb.. A new genus Treadwellphysa n. gen. is proposed to include those species having a newly described type of chaetae named spinifalcigers (exhibiting a mixture of falciger and spiniger blades), the base of maxillae II with a small elevation, and the ventral cirri with swollen base as transverse welt with short digitiform tip. Treadwellphysa n. gen. includes a new species, T. yucatanensis n. sp. and three other species previously included in Marphysa: T. amadae (Fauchald, 1977) n. comb., T. languida…

This study provides the first annotated check list of the Vespidae of Pakistan. It is based on the National Insect Museum collection and various studies in Pakistan. Among 105 identified taxa, 77 species and 28 subspecies are recorded in the four subfamilies Eumeninae, Masarinae, Polistinae and Vespinae. Three new records for the fauna of Pakistan are added, namely Anterhynchium mellyi, Antepipona ovalis and Eumenes coronatus coronatus. Among the total, 12 species/subspecies are endemic to Pakistan, namely Ancistrocerus pakistanus, Antepipona luteipes, Antodynerus flavescens karachiensis, Celonites nursei, Cyrtolabulus karachiensis, Eustenancistrocerus (Parastenancistrocerus) baluchistanensis, Katamenes dimidiatus watsoni, Knemodynerus lahorensis, Leptochilus (Neoleptochilus) hina, Leptochilus (Neoleptochilus) mirificus, Leptochilus (Neoleptochilus) umerolatus and Tachyancistrocerus pakistanus. Antepipona varentzowi (Morawitz, 1896) and Polistes rothneyi quatei van der Vecht, 1968 were incorrectly reported from Pakistan.

We describe a new, medium-sized Leptolalax species from Vietnam. Leptolalax petrops sp. nov. is distinguished from its congeners by a combination of having a medium-sized body (23.6-27.6 mm in 21 adult males, 30.3-47.0 mm in 17 adult females), immaculate white chest and belly, no distinct black markings on the head, highly tuberculate skin texture, toes lacking webbing and with narrow lateral fringes, and a call consisting of an average of four notes and a dominant frequency of 5.6-6.4 kHz (at 24.5-25.3 °C). Uncorrected sequence divergences between L. petrops sp. nov. and all homologous DNA sequences available for the 16S rRNA gene are >8%.

We present a phylogeny of all booted eagles (38 extant and one extinct species) based on analysis of published sequences from seven loci. We find molecular support for five major clades within the booted eagles: Nisaetus (10 species), Spizaetus (4 species), Clanga (3 species), Hieraaetus (6 species) and Aquila (11 species), requiring generic changes for 14 taxa. Additionally, we recommend that the Long-crested Eagle (Lophaetus occipitalis) and the Black Eagle (Ictinaetus malaiensis) remain in their monotypic genera, due to their distinctive morphology. We apply the recently resurrected genus Clanga for the spotted eagles (previously Aquila spp.) to resolve the paraphyly of the genus Aquila such that the clade including the Booted Eagle (H. pennatus), Little Eagle (H. morphnoides), Pygmy Eagle (H. weiskei), Ayres's Eagle (H. ayresii) and Wahlberg's Eagle (H. wahlbergi) can remain in the genus Hieraaetus. The Rufous-bellied Eagle should be retained in the genus Lophotriorchis. For consistency in English names, we recommend that the term "hawk-eagles" be used only for the species in…

We provide comparative comments on the morphology and provenance of the primary types of the species in the stingless bee genus Nannotrigona Cockerell. We offer an illustrated key to workers of all presently known species and designate lectotypes for the following species to stabilize their names: N. dutrae (Friese), N. mellaria (Smith), N. punctata (Smith), and N. schultezi (Friese). The type of Melipona minuta Lepeletier de Saint Fargeau could not be located and it remains an incertae sedis, but a possible member of Nannotrigona. A distinctive new species from western Ecuador, Nannotrigona camargoi n. sp. (type locality Ecuador, Pichincha) is also described and figured.

We present distribution data of all Alopoglossidae and Gymnophthalmidae lizards known from the Brazilian Amazonia, totaling 54 species-level taxa, belonging to 17 genera and two families. This represents 22 more species-level taxa than previously reported. Data were based on 17,431 specimens deposited in three North American and eight Brazilian museums, including the main collections harboring Amazonian material. Most species (~80%) are endemic to Amazonia; non-endemic species are mainly associated with open vegetation (savanna) enclaves or open dry (semideciduous) forest in Amazonia, with a few exceptions. As a whole, seven taxa (including one species complex) are widespread in Amazonia, six are restricted to eastern Amazonia, seven to western Amazonia, two to southwestern Amazonia, 11 to southern Amazonia, 11 to northern Amazonia (either in part of it or widespread in the Guiana region), and six to the southern peripheral portion of Amazonia. Besides, four species present unique distributions. Considering this study and the other three catalogues of distribution of lizards already…

Three new species of Marphysa Quatrefages, 1865 (Polychaeta: Eunicida: Eunicidae) are described from the south coast of China, M. tripectinata n. sp., M. multipectinata n. sp. and M. tribranchiata n. sp. with comments on the usefulness of pectinate chaetae to separate species. Marphysa sinensis Monro, 1934 is redescribed with a lectotype designated. The genus Marphysa is widely collected for bait and export for recreational fishermen and anglers in China and yet the number of species involved and their native distribution is currently unknown. Such information is critical for aquaculture programs which are rearing these species.

The Cobra-Preta (black snake in Portuguese) of Sao Tomé Island in the Gulf of Guinea has historically been referred to as Naja (Boulengerina) melanoleuca (Squamata: Elapidae). Its presence on the island has been traditionally explained as an introduction from the mainland by Portuguese settlers, supposedly to control the rat population. This explanation has been widely accepted by local authorities and even international conservation agencies. The taxonomic identity of this snake has remained undisputed by all taxonomists who have published about it, with the exception of L. Capocaccia in 1961. Arguments supporting the human introduction hypothesis are weak and are contradicted by historical, morphological and molecular data. Further, the biogeographic history of the Gulf of Guinea oceanic islands and recent insights on the taxonomic identity and evolutionary history of other taxonomic groups occurring there suggest that the Cobra-Preta, in fact, represents a distinct lineage of the melanoleuca group, endemic to São Tomé. We here describe the Cobra Preta as a new species. The new…

An updated species list of cynipids in Turkey and knowledge on their distribution and host plant/gall in the country are presented in this study. The present list has been based on previous studies in the literature and contains all reported cynipids from Turkey, including a new record (Andricus istvani Melika, 2008). In total, the Cynipidae in the Turkish fauna presently comprises 148 species in 25 genera and 9 tribes.

Two hundred and forty-four valid species in 36 genera are listed. The genus Telostegus Costa, 1887 with the species T. inermis (Brullé, 1833) are newly recorded from Russia. Lectotypes are designated for Salius desertorum F. Morawitz, 1891, Psammochares amurensis Gussakovskij, 1932, and Pompilus cardinalis F. Morawitz, 1891. The generic status of Batozonellus Arnold, 1937, stat. resurr. is reinstated. Five taxa: Ceropales pygmaea pygmaea Kohl, 1880, C. ruficornis Gussakovskij, 1931, Eoferreola anatolica Priesner, 1973, Hemipepsis sinensis (Smith, 1855), and Telostegus nigritulus (Klug, 1834) are excluded from the list of the Russian fauna. The world number of genus-group names of Pompilidae is clarified: 451 nominal names, including 42 unavailable names, were proposed. Of the 409 available names, 254 are currently considered valid.

In the 1850s, two species of "Spotted" Nightingale-Thrush (Aves: Catharus) were independently described from montane rainforests of Guatemala, C. dryas (Gould, 1855) and Ecuador, C. maculatus (Sclater, 1858). However, due to similarities in plumage color, C. maculatus was reclassified as a subspecies of C. dryas in 1878, a decision that has been upheld for 137 years. We collected multiple lines of evidence including phylogenetic analysis of mitochondrial DNA sequences (ND2), discriminant and principal components analysis of morphometric and vocal data, and statistical modeling of ecological niches, that collectively indicate that C. d. dryas and C. d. maculatus are independent species. We recommend restoring species status to C. maculatus of South America and applying the common name Sclater’s Nightingale-Thrush to this species.

Over the last three years, three new species of saw-browed diamond frogs (Rhombophryne serratopalpebrosa species group)-a clade of cophyline microhylid frogs native to northern and eastern Madagascar-have been described. We here review the taxonomy of these frogs based on a new multi-gene phylogeny of the group, which confirms its monophyly but is insufficiently resolved to clarify most intra-group relationships. We confirm Rhombophryne guentherpetersi (Guibé, 1974) to be a member of this group, and we re-describe it based on its type series and newly collected material; the species is characterised by small superciliary spines (overlooked in its original description), as well as large tibial glands and an unusually laterally compressed pectoral girdle. We go on to describe two new species of this group from northern Madagascar: both R. diadema sp. nov. from the Sorata Massif and R. regalis sp. nov. from several sites in the northeast of the island possess three superciliary spines, but they are characterised by several subtle morphological and osteological differences. The new…

Parsley frogs (Pelodytes) comprise the only genus in the family Pelodytidae, an ancient anuran lineage that split from their closest relatives over 140 million years ago. Pelodytes is a Palearctic group restricted to Western Eurasia including three extant species: the eastern species P. caucasicus, endemic to the Caucasus area, and two closely related species inhabiting Western Europe: the Iberian endemic P. ibericus and the more widespread P. punctatus. Previous studies based on mitochondrial and nuclear DNA markers have revealed the existence of two additional lineages of Parsley frogs in the Iberian Peninsula, which have been flagged as candidate species. Here, we integrate novel molecular, morphological and bioacoustical data to assess the differentiation of the four western Parsley frog lineages. Species trees and Bayesian population assignment analyses based on nuclear markers confirm previous studies and concordantly delineate four parapatric lineages with narrow hybrid zones. Mitochondrial divergence is low (< 2% pairwise distances in the 16S rRNA gene), in line with…

Species of Marphysa belonging to the Aenea-group have compound falcigers as the subacicular chaetae along the entire body. Around 30 species belong to this group, among these, two have originally been described based on Australian specimens, M. bifurcata and M. sessilobranchiata. Here, we redescribe both species based on type and non-type material and describe a species new to science, M. pseudosessiloa n. sp., including intraspecific variation. Informative features for the identification of these species are relative length of prostomial appendages in relation to prostomium, shape of notopodial cirri, left MxIV plate, left and right MxIV attachment lamellae and placement of branchial stem. A taxonomic key to species of Marphysa currently reported from Australia is also provided.

Eopelma gibsoni sp. nov. is described based on a male recently collected in Borneo. It is the second species of the genus to be described, and the first species of chalcid wasp in which a pattern of dark stripes on the compound eye is described. The presence of similar dark stripes on the eyes of other chalcid wasps is discussed, highlighting the importance of citizen science. The description is accompanied by a DNA barcode sequence to assist future identification and association of the sexes. The phylogenetic position of E. gibsoni based on 28S DNA sequences is discussed.

The Liriomyza (Diptera: Agromyzidae) of Canada and Alaska is revised, with species keyed and illustrated, and new host and geographic records provided. Eighty one species are recognized, including 24 new to science: L. agrios, L. albispina, L. anatolis, L. aphila, L. apilaca, L. aquapolis, L. arenarium, L. atrassimilis, L. bicolumbis, L. charada, L. cracentis, L. elevaster, L. emaciata, L. fumeola, L. gibsoni, L. griffithsi, L. hilairensis, L. limopsis, L. mesocanadensis, L. pilicornis, L. pistilla, L. rigaudensis, L. taraxanox, L. taraxanuda, L. tryssos. Ten species known from the United States are recorded as new to Canada: L. artemisiae Spencer, L. assimilis (Malloch), L. baccharidis Spencer, L. helianthi Spencer, L. merga Lonsdale, L. minor Spencer, L. sabaziae Spencer, L. temperata Spencer, L. violivora (Spencer) and L. virgo (Zetterstedt). Palaearctic species new to North America include L. wachtli Hendel and L. flaveola (Fallén); while the latter species has been recorded in North America before, all previous records represent misidentifications. Hosts are recorded for the…

Four black fly species of the Simulium striatum species group have been recorded in Thailand. These species are morphologically highly similar in all developmental stages except for the number and arrangement of the pupal gill filaments. In this study, we used multiple characters sources, including morphology, cytology, molecular biology and ecology, to test the hypothesis of conspecificity for S. quinquestriatum (Shiraki), S. nakhonense Takaoka & Suzuki and S. chiangmaiense Takaoka & Suzuki. A molecular study based on the cytochrome c oxidase subunit I (COI) was unable to separate these taxa. In contrast, the elongation complex protein 1 (ECP1) sequences clearly differentiate S. quinquestriatum from S. chiangmaiense and S. nakhonense. However, the latter two taxa could not be differentiated based on molecular DNA sequences. Simulium chiangmaiense and S. nakhonense are also similar in the larval habitat characteristics and have undifferentiated polytene chromosome banding patterns. Morphological examination of the number and arrangement of the pupal gill filaments found a number of…

The new species Epeorus (Caucasiron) bicolliculatus sp. nov. is described based on larvae and adults. Diagnostic characters are given with regard to the related species. The most pronounced difference is represented by protuberances on larval abdominal terga II-IX, present exclusively in E. (C.) bicolliculatus sp. nov. Primary data on the biology and distribution of the new species are also provided. Delimitation of the new species is verified by the analysis of COI (barcode) sequences. Barcode data for all Caucasian species of the subgenus Caucasiron are provided for the first time and compared with E. (C.) bicolliculatus sp. nov.

The paper is the first illustrated check-list of the freshwater Gastropoda of the state of Mongolia. The authors examined their own samplings made in 2009–2012 as well as collections of other explorers and zoological museums (mostly those of Russia). In total, 35 nominal species of four families (Valvatidae, Lymnaeidae, Physidae, and Planorbidae) have been included into annotated list, with remarks on their distribution, ecology, taxonomic status, and nomenclature. All species are illustrated by pictures of their shells (including some type specimens). The fauna of freshwater Gastropoda of Mongolia is taxonomically impoverished as compared to the fauna of southern Siberia and other adjacent areas. In particular, no representatives of such families as Acroloxidae and Bithyniidae were found to live there as well as no species of Anisus, Aplexa, Planorbarius, Planorbis, Stagnicola and some other genera of aquatic snails broadly distributed in Palearctic. From the zoogeographic point of view, the recent fauna of aquatic Gastropoda of Mongolia consists of species belonging to three…

The sawfly genus Euura of the tenthredinid subfamily Nematinae, in which species level taxonomy has long been regarded as controversial, is particularly species rich in northern parts of the Holarctic. Among a majority of species with more or less free-living larvae, a sizeable minority belongs to a monophyletic lineage whose larvae complete their whole development in galls. We present illustrated keys to the adults and galls of 66 gall-inducing Euura species that occur, or might occur, in northern Europe. The distribution of these species is briefly reviewed, with an emphasis on the fauna of Sweden, where 55 species are now definitely recorded, two of them for the first time (E. bigallae, E. myrtilloidica). The species-level taxonomy of gall-inducing Euura remains partly problematic. Nominal species described on the basis of experimentally tested or assumed host plant specificity, but which cannot be recognised using morphological or genetic characters, are treated as conspecific with currently indistinguishable segregates ("host-plant races") associated with other Salix species.…

We describe Oligodon saiyok sp. nov. from Benjarat Nakhon Cave Temple, Sai Yok District, Kanchanaburi Province, western Thailand. It is characterized by a maximal known SVL of 626.1 mm; 13 maxillary teeth, the posterior two enlarged; 8 supralabials; 17-17-15 dorsal scale rows; 181–187 ventrals and 38–43 subcaudals; a single anal; hemipenes extending in situ to the 18th subcaudal; dorsum with 21–22 dark blotches or white rings without vertebral or lateral stripes; and venter with a dense network of subrectangular dark blotches. It is the 7th squamate species believed to be endemic to Sai Yok District.

The relationships among and within the families that comprise the orthopteran superfamily Stenopelmatoidea (suborder Ensifera) remain poorly understood. We developed a phylogenetic hypothesis based on Bayesian analysis of two nuclear ribosomal and one mitochondrial gene for 118 individuals (84 de novo and 34 from GenBank). These included Gryllacrididae from North, Central, and South America, South Africa and Madagascar, Australia and Papua New Guinea; Stenopelmatidae from North and Central America and South Africa; Anostostomatidae from North and Central America, Papua New Guinea, New Zealand, Australia, and South Africa; members of the Australian endemic Cooloola (three species); and a representative of Lezina from the Middle East. We also included representatives of all other major ensiferan families: Prophalangopsidae, Rhaphidophoridae, Schizodactylidae, Tettigoniidae, Gryllidae, Gryllotalpidae and Myrmecophilidae and representatives of the suborder Caelifera as outgroups. Bayesian analyses of concatenated sequence data supported a clade of Stenopelmatoidea inclusive of all…

The Lepidoptera of North America Network, or LepNet, is a digitization effort recently launched to mobilize biodiversity data from 3 million specimens of butterflies and moths in United States natural history collections (http://www.lep-net.org/). LepNet was initially conceived as a North American effort but the project seeks collaborations with museums and other organizations worldwide. The overall goal is to transform Lepidoptera specimen data into readily available digital formats to foster global research in taxonomy, ecology and evolutionary biology.

We evaluate the monophyly and phylogenetic relationships of the Pristimantis leptolophus species group and describe its external morphology, osteology, and some myological characteristics. We also compare the P. leptolophus species group to other related species groups. The P. leptolophus group is not monophyletic due to the inclusion of P. acatallelus, formerly believed to be part of the P. devillei group. The revised P. leptolophus group is composed of nine named species and six unnamed species. Based on our results, we recognize a new species group, the P. boulengeri species group, composed of eight species, many of which were previously assigned to the P. lacrimosus species group.

The orthopterans are diverse insects and play important roles in the ecosystem as well as having "love-hate relationship" with humans. Documentation of diversity in Southeast Asia has long history but remains incomplete. Using information of type specimens and Geographic Information System (GIS) techniques, we investigated the following questions on new species discovery for the region, specifically: (1) How are new species discoveries of orthopterans distributed in Southeast Asia? (2) How have new species discoveries changed with time? (3) How do new species discoveries relate to the countries of the type depositories? We found that new species discoveries, relative to sampling, are fragmentary in Southeast Asia and changes with different time periods. We also find type depositories tightly linked to the human (colonial) history of Southeast Asian countries. We provide some recommendations and hope that this can help to accelerate the study of orthopteran diversity in the region.

The new, small cavernicolous species Helmablatta louisrothi gen. et sp. n. (Nocticolidae) from the Tan-Phu cave (Vietnam) is one of the most morphologically interesting cockroaches. The extremely modified upstanding tergal gland composite from three tergites and may serve for gripping the female head during copulation. This presumption is supported by the presence of a central big hook on tergite 8. Furthermore, both wing pairs are uncommonly adapted to help releasing sex pheromones without raising the wings. Histone 3 DNA-based maximum likelihood analyses indicate a recent origin and close phylogenetic relationship between Nocticola spp. and Helmablatta sp.-consistent with the Quaternary age of the source lava tubes.

The Andean genus Rhaucus Simon 1879 is revised. Five valid species are recognized, including Rhaucus florezi sp. nov. The following nomenclatural acts are proposed. At genus level: Megarhaucus Mello-Leitão, 1941, Neorhaucus Pickard-Cambridge, 1905 and Pararhaucus Pickard-Cambridge, 1905 are considered junior subjective synonyms of Rhaucus. At species level: Neorhaucus aurolineatus Pickard-Cambridge, 1905 is considered a junior subjective synonym of Rhaucus vulneratus Simon, 1879; Rhaucus (Rhaucus) tristis Sørensen, 1932, Rhaucus (Rhaucus) muticus Sørensen, 1932 and Pararhaucus obscurus Pickard-Cambridge, 1905 are considered junior subjective synonyms of Rhaucus quinquelineatus Simon, 1879 (the latter combination is restored from current combination Flirtea quinquelineata); Flirtea paucimaculata Roewer, 1963, Rhaucus (Rhaucus) geographicus Sørensen, 1932, Metarhaucus reticulatus Roewer, 1912 and Metarhaucus fuscus Pickard-Cambridge, 1905 are considered junior subjective synonyms of Erginus serripes Simon, 1879 (that is here combined as Rhaucus serripes comb. rest.). Megarhaucus…

We review the trans-Andean species of Pimelodus from Colombia, Panamá, and Venezuela. Based on meristic and morphometric data of preserved specimens, four of five species reported from this region are considered valid and two new Colombian species are described. Here we review Pimelodus coprophagus Schultz, 1944 from Lake Maracaibo Basin of Venezuela and Colombia; Pimelodus grosskopfii Steindachner, 1879 from Magdalena River Basin; Pimelodus navarroi Schultz, 1944 from Lake Maracaibo Basin of Venezuela and Colombia; and Pimelodus punctatus (Meek & Hildebrand, 1913) from Atrato, Baudó, and Tuyra River Basins of Colombia and Panamá. Pimelodus crypticus new species is described from the upper Cauca river drainage. Pimelodus yuma new species is described from the Cauca, Magdalena, and Sinú river drainages. A key for species identification and geographical ranges is provided. We also reidentify trans-Andean specimens previously reported as Pimelodus blochii Valenciennes, 1840, a widespread cis-Andean species, or species complex, that ranges across the coastal rivers of the Guianas and…

A new genus Arquatopotamon gen. n. of the family Potamidae Ortmann, 1896, is established and a new species, Arquatopotamon jizushanense sp. n. from Yunnan Province, China is described. The new genus is established based on the distinctive distal part of the male first gonopod, with arched-shaped subterminal and terminal segments (in mesioventral view) and female gonopores (vulvae) on thoracic sternites 5/6 and a combination of characters including the carapace and male telson, while it is similar to the five known genera in Yunnan Province and adjacent area, Tenuipotamon Dai, 1990, Pararanguna Dai & Chen, 1985, Trichopotamon Dai & Chen, 1985, Potamiscus Alcock, 1909 and Aparapotamon Dai & Chen, 1985, in having a third maxilliped exopod without a flagellum. Present molecular data based on a barcoding marker of 16S rDNA provide strong support for the genus as being new.

We describe Tanaopsis japonica sp. nov. from intertidal and nearshore habitats around Hokkaido Island, northern Japan. This species closely resembles T. chotkarakde Bird & Bamber, 2000 and T. rawhitia Bird, 2011 in having the uropod with the endopod biarticulate and the exopod uniarticulate, but differs from them in the following characters: pereonite 4 as long as pereonite 5; mandibles lacking the molar; the number of simple setae on the antenna, propodal palm, and dactylus of pereopods 1–3; the number of spiniform setae on the cutting surface of the chelipedal dactylus; and the number of setae on the pleopods. We also determined a nearly complete nucleotide sequence for the 18S rRNA gene in T. japonica. In both sexes, Tanaopsis japonica sp. nov. bears serial ridges and grooves on the chela, antennule, and antenna. Parallel, fringed hatch marks on the chelipedal dactylus may function in stridulation. A series of denticulate ridges on the dorsal surface of antennal article 2 faces the ventral side of article 1 of the antennule, where there is a ventral series of slight grooves.…

We provide an integrative analysis of the diversity of the E. multiocellata—E. przewalskii species complex in Central and Middle Asia using morphological and molecular (COI DNA-barcoding) data. We report preliminary data on mtDNA variation within this group and clarify the taxonomic status and distribution of the members of the species complex. We also provide a description of a new Eremias species from Eastern Kazakhstan and western Mongolia, where it occurs in sympatry with E. multiocellata sensu stricto, from which it can be clearly differentiated using both morphological and molecular characters. The new species, described as Eremias dzungarica sp. nov., is assigned to the subgenus Pareremias on the basis of the following features: subocular not reaching mouth edge; one frontonasal; two supraoculars; the row of small granular scales between supraoculars and frontal with frontoparietals absent; distance between the femoral pore rows being wide; femoral pore rows not reaching knee-joint; coloration pattern with light colored ocelli with black edging. The new species can be…

The psyllids or jumping plant-lice of Israel are reviewed from literature records and collected insect material. Eighteen species are reported from Israel for the first time, bringing the total to 94 species from 35 genera, in five families. Three species are described as new: Caillardia springatei Spodek & Burckhardt, Craspedolepta merzi Spodek & Burckhardt and Eremopsylloides vicinus Spodek & Burckhardt, and one new combination is proposed: Crastina heslopharrisoni (Samy, 1972), comb. nov. from Craspedolepta. Six additional unidentified species are recorded from the genera Bactericera (2 species), Cacopsylla, Craspedolepta, Eryngiofaga and Pachypsylloides. We list new taxa for Israel, update the taxonomy and indicate the known geographic distribution for each species. Host plants and economically important psyllids are discussed. A key to adult psyllids is provided.

The first extant representatives of the pseudoscorpion family Feaellidae from Southeast Asia are described. Cybella n. gen. is proposed for Cybella deharvengi n. sp. (type species), collected from an isolated limestone hill in Hon Chong Province, Vietnam, and C. bedosae n. sp., found in a limestone cave in Kampuchea, Cambodia. Cybella species seem to be restricted to karst formations and are probably troglophilic. The type localities of the two known species are threatened by quarrying activities, these being particularly pressing in the case of C. deharvengi n. sp. Cybella shows important differences from other Feaellidae that require a modification of the familial diagnosis and justify the erection of a new subfamily, Cybellinae. The discovery of this group provides insights into the evolution of the unusual morphology of the family, notably concerning the pleural plates of Feaellinae, which are lacking in Cybellinae. The smaller sclerites of the pleura of Pseudogarypidae and Feaellidae are shown to be muscle apodemes, which provide an additional synapomorphy for Feaelloidea. Two…
