Until recently, almost all barbastelle populations inhabiting Asia, from Iran to Japan and Taiwan, were recognized as a single species, Barbastella darjelingensis. However, in recent years, it was shown that the taxonomic diversity within the genus Barbastella was underestimated, and B. darjelingensis sensu lato is highly variable, both morphologically and genetically. Transcaucasian and Central Asian populations were already raised to the species level as B. caspica. Populations from eastern and south-eastern Asia are still understudied and likely encompass undescribed species. Comparing results from mtDNA sequences, skull morphometry and baculum shape, we concluded that one of these putative species is represented by populations inhabiting Honshu, Hokkaido and Kunashir Islands, and provide a scientific description of this new species. Populations from Taiwan, southern China and Indochina represent a sister mitochondrial clade to this new species. However, available morphological material from these areas did not demonstrate a significant difference from the Himalayan B. darjelingensis. Therefore, we refuse to give this form any taxonomic status until further studies of more vast material are done.

Morphological And Molecular Data

An investigation of the taxonomic status of Pareas hamptoni (Hampton's Slug snake) based on morphological and molecular data revealed a new distinct species from the Golden Triangle region (comprising parts of southern China, and adjacent Laos and Thailand). The new species is shown to be a sister species to P. hamptoni but can be separated from the latter by having 3–5 dorsal scale rows at midbody slightly keeled (vs 5–9 scales strongly keeled); a lower number of ventrals, 170–188 (vs 185–195); and a lower number of subcaudals, 67–91 (vs 91–99). The new species is currently known from northwestern Thailand, northern Laos, and the southern part of Yunnan Province in China at elevations of 1,160–2,280 m a.s.l. We suggest that the new species to be considered of Least Concern (LC) in the IUCN‘s Red List categories. Problems of taxonomy and actual distribution of the P. hamptoni complex are briefly discussed; our results show P. hamptoni is now reliably known only from Myanmar and Vietnam, but its occurrence in Yunnan Province of China is likely.

A New Species

Cryptobenthic fauna investigations are highly relevant at studying biodiversity of regions. Studies of the species composition of Gobiesocidae family were carried out in order to clarify ichthyofauna of different regions, and a new species for the Black Sea coastal zone of Crimea was found. Information about its morphology, biology, behavior and other characteristics is very important because of weak study and indeterminate taxonomic status of this species. As a result of morphological studies of the Crimean specimens no significant difference with the type of the Atlantic-Mediterranean populations has been proven. Naturalization of small-headed clingfish in coastal waters of Crimea has been confirmed and some population characteristics, such as a length-weight relationship, have been described. Peculiarities of habitat which which small-headed clingfish prefers and features of localization, enabling competitiveness have been identified. Identification keys were compiled and are given in the paper.

A New Species

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 specimens, and suggest that M. kuatunensis is likely to be restricted to eastern China.

Critical Translation

The Dutch ichthyologist Pieter Bleeker described 34 species, including a new genus and five new species from a collection of fishes sent to him from the Cape of Good Hope by the French explorer, naturalist and diplomat, F.L. de Castelnau in 1858. A careful search of the Naturalis collection in Leiden found almost all the specimens received by Bleeker from Castelnau, including hitherto unrecognised types. Based on examination of this collection and a critical translation of Bleeker’s 1859 paper on the fishes of the Cape of Good Hope it has been possible to resolve the taxonomic status of Bleeker’s genus Pagrichthys (Pagrichthys castelnaui Bleeker, 1859, type by monotypy), previously considered a synonym of Sparus Linnaeus, 1758 but here regarded as a synonym of Lithognathus Swainson, 1839. The identity of the various species described by Bleeker, and type status of his new species are clarified: Cantharus castelnaui Bleeker, 1859 is a synonym of Pachymetopon blochii (Valenciennes, 1830); Pagrichthys castelnaui Bleeker, 1859 is a synonym of Lithognathus lithognathus (Cuvier, 1829); Seriola capensis Bleeker, 1859 (not previously recognised as a valid species) is a synonym of Seriola lalandi Valenciennes, 1833; Clinus dubuis Bleeker, 1859 (based on a misspelling of Castelnau’s ms name dubius) is a valid name, and a synonym of Clinus superciliosus (Linnaeus, 1758); and Clinus dorsalis Bleeker, 1859 is valid as Muraenoclinus dorsalis (Bleeker, 1859).

The Ctenistini fauna of China is insufficient documented. In this paper the first Chinese species of the genus Ctenisomorphus Raffray, 1890, C. yinggelingensis sp. nov., is described and separated from congeners based on two male and four female specimens collected at Yinggeling Natural Reserve, Hainan Island, southern China. Images of the habitus and major diagnostic characters of the new species are provided. The taxonomic status of Largeyeus anhuianus J.-K. Li, 1993 distributed in Anhui, eastern China is discussed, and the genus is placed as a junior synonym of Poroderus Sharp, 1883 syn. nov., resulting in P. anhuianus comb. nov.

A new species of Weiseronyssus (Mesostigmata: Diplogyniidae) is described from adult females and males taken from Oryctes nasicornis (L.) (Coleoptera: Scarabaeidae) in northern Iran. The genus was previously known from a single species associated with an undetermined dynastine scarab from southern China. The generic diagnosis is updated and a key to the genera of Diplogyniidae is presented.

Pyura stolonifera is a large solitary ascidian found in Africa, Australasia and South America. The taxonomic status of different populations of this species is disputed, especially since there is evidence for several distinct morphological and genetic units that point towards the existence of multiple cryptic species. While some researchers still recognize P. stolonifera as a single species, others treat the different populations as distinct species. Here, we present a revision of the P. stolonifera species complex based on the examination of samples from all regions where there are reliable reports of this taxon. We recognize four species that are both morphologically and genetically distinct, one of which is new to science and is formally described here. This species is morphologically distinct from the other three members of the species complex in terms of the colour and texture of the tunic, the arrangement of the gonads within the gut and the shape of the dorsal tubercle, among other characters. We name the new species Pyura dalbyi after Dr. J.E. Dalby Jr., whose research on its ecology and distribution provided the incentive for examining this species more closely.

ABSTRACTThis paper evaluates the taxonomy, biostratigraphy, and palaeogeographical significance of the Cambrian bradoriid arthropods of China, the majority of which occur in the lower Cambrian of SW China. Of bradoriid faunas world-wide, Chinese occurrences yield the greatest number of specimens and a comparatively high diversity at all taxonomic levels. Nevertheless, taxonomic diversity is much less than previously supposed. Some 80 bradoriid genera and nearly 300 species have been proposed on the basis of Chinese material. By contrast, in our study, which encompasses all of the important Chinese bradoriid faunas, we recognise only 16 genera and 21 species, including those treated under open nomenclature. Interpretation of deformed specimens as discrete species and lack of application of the rules of the International Code of Zoological Nomenclature resulted in taxonomic splitting and a proliferation of names. There are an additional 12 poorly known monotypic genera of uncertain systematic status that are listed but not treated further herein. One phosphatocopid species, a group originally thought closely related to the Bradoriida, is also described.Most Chinese bradoriid material is known from Yunnan Province; the group also occurs in Guizhou, Henan, Hubei, Hunan, Liaoning, Qinghai, Shaanxi, Sichuan, Xinjiang and Zhejiang provinces. The first bradoriids occur just below the Abadiella trilobite Biozone. They are most prolific and diverse in the Qiongzhusian Stage, constituting the most abundant animal group; the succeeding Canglangpuian Stage contains fewer individuals and species. A previously proposed bradoriid biozonal scheme lacks rigour and is of little practical value: of the five supposed biozones, two correspond to trilobite zones and three are based on taxa that herein are considered to belong to a single species.Palaeogeographically the bradoriids occur in the Middle and especially the Western subprovinces of the Cambrian of the SW China (Yangtze) Platform. Almost all of the bradoriid genera and species are endemic to that region. The palaeogeographical links with other bradoriid faunas are mostly within the Redlichiid trilobite Realm, with areas such as N China, Australia and parts of central Asia.

It is widely accepted among the Cladocera (Crustacea) taxonomists that almost all “cosmopolitan” taxa are represented by some un-revised complexes of cryptic species. But many macro taxa of the cladocerans are still unrevised. The aim of this work is to analyze the taxonomic status of Oriental populations of the genus Bosminopsis Richard, 1895 (Anomopoda: Bosminidae) based on morphological characters. We have studied populations from India, Myanmar, Cambodia, Thailand, Laos, Vietnam, Philippines, Malaysia and Papua New Guinea and concluded that Oriental populations belong to a single species, Bosminopsis africanus (Daday, 1908), initially described from Africa. Analysis of literature data confirms that is widely distributed through whole Oriental zone. A single large mucro, or the mucro accompanied by an additional small spine in both sexes, is the main trait which differentiates B. africanus from B. zernowi Linko, 1901 distributed in more northern regions of Eurasia.

Abstract— Populations of Carex sect. Rhynchocystis (Cyperaceae) from the Macaronesian archipelagos (Azores and Madeira) have traditionally been treated either as a variety of the widely distributed Western Palearctic C. pendula, or directly synonymized under it. However, recent phylogenetic studies have shown that Azorean populations of C. pendula display a certain degree of differentiation from mainland plants, while the phylogenetic relationships of Madeiran populations remain unclear. Here we perform an integrated systematic study focused on the Macaronesian populations of Carex sect. Rhynchocystis to elucidate their phylogenetic relationships and taxonomic status. We reconstructed a molecular phylogeny based on five DNA regions and conducted a multivariate morphological analysis. Divergence time estimates show that the Macaronesian populations can be traced back to a Plio-Pleistocene origin. Our results suggest that these island populations of C. pendula are better treated as two distinct species within Carex sect. Rhynchocystis (i.e. C. leviosa from the Azores and C. sequeirae from Madeira). We provide morphological characters to differentiate the new species from C. pendula s. s., detailed descriptions of the three taxa, a revised key for the entire section, as well as detailed analytical drawings of the two newly described species. We also perform a critical evaluation of the taxonomic diversity of Carex in the Azores and Madeira. Finally, we informally assessed the conservation status of the new species at a global scale under IUCN categories and criteria, resulting in the proposal of the categories Least Concern for C. leviosa and Critically Endangered for C. sequeirae.
