We evaluate the hypothesis of Centrolene lema as a species distinct from C. gorzulae using morphological, bioacoustic and genetic comparisons. Our results show that there are no consistent differences in any of these three areas; hence, we present C. lema as a synonym of C. gorzulae. Additionally we provide new data on the distribution and ecology of the species.

As Species

AbstractTaxonomy is replete with groups where the species identity and classification remain unresolved. One such group is the widely distributed Hanuman langur (Colobinae: Semnopithecus). For most part of the last century, Hanuman langur was considered to be a single species with multiple subspecies. Nevertheless, recent studies using an integrative taxonomy approach suggested that this taxon is a complex, with at least three species. However, these studies did not include the Himalayan population of the Hanuman langur whose taxonomic status remains unresolved. The Himalayan population of Hanuman langurs have been classified as a distinct species with multiple subspecies or have been subsumed into other species. These classification schemes are wholly based on morphological characters and which are sometimes insufficient to delimit different species. Here, we have integrated data from multiple sources viz. morphology, DNA, and ecology to resolve the taxonomy of the Himalayan langur and to understand its distribution limit. Our results with three lines of evidence corresponding to three different species concepts show that Himalayan langur is a distinct species from S. entellus of the plains. Additionally, these results did not show any support for splitting of the Himalayan langur into multiple subspecies. Our study supports the classification proposed by Hill (1939) and we recommend Semnopithecus schistaceus, Hodgson 1840 as species name for the Himalayan langur and subsume all the known subspecies into it.

The aganippine shield-backed trapdoor spiders of the monophyleticnigrum-group ofIdiosomaAusserers. l.are revised, and 15 new species are described from Western Australia and the Eyre Peninsula of South Australia:I.arenaceumRix & Harvey,sp. n.,I.corrugatumRix & Harvey,sp. n.,I.clypeatumRix & Harvey,sp. n.,I.dandaraganRix & Harvey,sp. n.,I.formosumRix & Harvey,sp. n.,I.gardneriRix & Harvey,sp. n.,I.gutharukaRix & Harvey,sp. n.,I.incomptumRix & Harvey,sp. n.,I.intermediumRix & Harvey,sp. n.,I.jarrahRix & Harvey,sp. n.,I.kopejtkaorumRix & Harvey,sp. n.,I.kwonganRix & Harvey,sp. n.,I.mcclementsorumRix & Harvey,sp. n.,I.mcnamaraiRix & Harvey,sp. n., andI.schoknechtorumRix & Harvey,sp. n.Two previously described species from south-western Western Australia,I.nigrumMain, 1952 andI.sigillatum(O. P.-Cambridge, 1870), are re-illustrated and re-diagnosed, and complementary molecular data for 14 species and seven genes are analysed with Bayesian methods. Members of thenigrum-group are of long-standing conservation significance, andI.nigrumis the only spider in Australia to be afforded threatened species status under both State and Commonwealth legislation. Two other species,I.formosumRix & Harvey,sp. n.andI.kopejtkaorumRix & Harvey,sp. n., are also formally listed as Endangered under Western Australian State legislation. Here we significantly relimitI.nigrumto include only those populations from the central and central-western Wheatbelt bioregion, and further document the known diversity and conservation status of all known species.

Collecting much-needed information on the taxonomy, distribution, and ecology of cave-dwelling shrimp is the foundation for addressing urgent challenges in conservation biodiversity and these fragile ecosystems. Caridina unicolor sp. nov., a new atyid shrimp from an underground stream of Yaoshui Cave, Daqikong scenic area, Libo County, Guizhou Province, southwestern China is described based on morphology and DNA analysis (mitochondrial COI). Caridina unicolor sp. nov. differs from epigean congeners by the variable eye, ranging from reduced to blind; colorless body and appendages; the long stylocerite and sixth abdominal segment; and relatively large eggs. In comparison to other cave species, Caridina unicolor sp. nov. presents a long rostrum and stylocerite; the slender sixth abdominal segment; and the unique shape of appendix masculina. The data on the habitat, ecology, and the levels of threat are provided and suggest that it be categorized as Critically Endangered (CR).

Collecting much-needed information on the taxonomy, distribution, and ecology of cave-dwelling shrimp is vital for addressing the urgent challenges in conservation biodiversity in fragile cave ecosystems. Caridina incolorsp. nov., a new atyid shrimp from an underground stream of Yaoshui Cave, Daqikong scenic area, Libo County, Guizhou Province, southwestern China is described based on morphology and DNA analysis (mitochondrial COI). Caridina incolorsp. nov. differs from epigean congeners by its smaller eyes which range from reduced to completely blind; colorless body and appendages; long stylocerite and sixth abdominal segment; and relatively large eggs. In comparison to other cave species, Caridina incolorsp. nov. presents a long rostrum and stylocerite; slender sixth abdominal segment; and unique shape of the appendix masculina. Data on the habitat, ecology, and levels of threat are provided and suggest that it should be categorized as Critically Endangered (CR) under the current IUCN criteria.
