We found a uniquely colored dicroglossid frog of the genus Occidozyga from western Sarawak, East Malaysia. It is divergent from other congeners in morphology and mtDNA sequences. In a molecular phylogeny, this species is the sister lineage to the continental species O. lima and O. martensii with weak support. The species is small with SVL 16–18 mm in males and 18–19 mm in females, without dorsolateral fold but with transverse wrinkles on dorsum, tips of fingers lacking disks but of toes with disks, only first and second toes webbed to disks, and orange-brown dorsum with dark brown band. We thus describe it as a new species.

Seven species of freshwater crabs from three families are recorded from and around the Danum Valley Conservation Area in Sabah, Malaysian Borneo: Thelphusulacapillodigitus sp. n., Thelphusuladicerophilus Ng & Stuebing, 1990, Arachnothelphusaterrapes Ng, 1991, Terrathelphusasecula Ng & Tan, 2015, Parathelphusavalida Ng & Goh, 1987 (new record) (Gecarcinucidae); Isolapotamoningeri Ng & Tan, 1998 (Potamidae); and Geosesarmadanumense Ng, 2002 (Sesarmidae). The new species of Thelphusula Bott, 1979, can be distinguished from all congeners by a unique combination of morphological features, most notably the presence of dense patches of short setae on the fingers of the adult male chelipeds, as well as the structure of the male first gonopod. Arachnothelphusaterrapes is confirmed to be a phytotelm species. A key to all species in the conservation area is provided.

Lines Of Evidence

Abstract The systematics and taxonomy of the broadly distributed bats of the genus Cynomops has changed considerably in the last few years. Among the major changes, Cynomops abrasus was split into two species of large-bodied forms (Cynomops mastivus and C. abrasus) distributed east of the Andes. However, large Colombian specimens identified as C. abrasus from the western side of the Andes had yet to be included in any revisionary work. Phylogenetic analysis performed in this study, using mtDNA sequences (Cytochrome-b), revealed that these Colombian individuals are more closely related to Cynomops greenhalli. Morphological and molecular data allowed us to recognize populations from western Colombia, western Ecuador and northwestern Peru, as members of a new species of Cynomops. Characters that allow for its differentiation from C. greenhalli include a larger forearm, paler but more uniform ventral pelage, more globular braincase, and well-developed zygomatic processes of the maxilla (almost reaching the postorbital constriction). This study serves as another example of the importance of including multiple lines of evidence in the recognition of a new species. Given its rarity and the advanced transformation of its habitat, this new species is particularly important from a conservation perspective.

Abstract Raphidascaris (Sprentascaris) andersoni n. sp. (Nematoda: Raphidascarididae) collected in the intestine of the humphead cichlid Gymnogeophagus balzanii (Perugia) from the Pantanal wetlands, State of Mato Grosso do Sul (Brazil) is described and genetically characterized. The new species differs from its congeners mainly by having a conspicuous papilla-like formation slightly anterior to the cloacal aperture. Furthermore, males of R. (S.) lanfrediae and R. (S.) mahnerti have caudal alae, and R. (S.) hypostomi and R. (S.) pimelodi lack lateral alae, whereas in the new species caudal alae are absent and lateral alae present. The remaining congeners, namely, R. (S.) marano and R. (S.) saltaensis differ from Raphidascaris (Sprentascaris) andersoni n. sp. mainly because males have three pairs of postcloacal papillae (vs five pairs). In the phylogenetic reconstructions, using three nuclear genetic markers (18S, ITS1-5.8S-ITS2 and 28S rDNA) and one mitochondrial (cox1 mtDNA), the new species was separated from other representatives of Raphidascarididae, and the absence of monophyly in Hysterothylacium and Raphidascaroides was confirmed. Moreover, the subgenera Sprentascaris and Ichthyascaris appeared to be monophyletic. Therefore, even though Raphidascaris (Raphidascaris) was apparently not monophyletic, the subgenera of Raphidascaris should be re-erected as valid genera. The updated diagnoses of Ichthyascaris, Raphidascaris and Sprentascaris are given. The present study represents the first parasitological survey in G. balzanii.

A New Species

A new species of Maytenus has been discovered in the Brazilian Atlantic Forest. The new taxon, Maytenus nemorosa, occurs mostly in ombrophilous rain forests at an elevation of 500 m to 1200 m. Maytenus nemorosa resembles M. gonoclada but differs from it by possessing oblong-elliptical leaves with entire margins and larger fruits with thicker pericarp walls. A phylogenetic analysis was conducted with nrITS and plastid matK regions, including the new species and additional taxa available from the NCBI-GenBank. The results from the phylogenetic analysis places Maytenus nemorosa nested within a clade of species that have fruits possessing a coriaceous pericarp and close to both Maytenus gonoclada and Maytenus salicifolia, as expected from morphological similarities. Additionally, M. cardenasii and M. erythrocarpa, from Bolivia, are both recognized as new synonyms for M. floribunda after an examination of their descriptions, types, and diverse collections.

A New Species

Five strains of the genus Coelastrella were studied from the collections of live cultures of algae of the Institute of Biology, Syktyvkar, Russia (SYKOA Ch-045-09, SYKOA Ch-047-11, SYKOA Ch-072-17) and the Siberian Institute of Plant Physiology and Biochemistry, Irkutsk, Russia (IRK-A 2, IRK-A 173). It was found that, despite their high morphological similarity, the strains have different phylogenetic relationships. The analysis of the 18S rDNA and ITS1-ITS2 showed that the studied strains belong to the species: C. terrestris (IRK-A 173), C. oocystiformis (SYKOA Ch-045-09; IRK-A 2) and C. aeroterrestrica (SYKOA Ch-047-11). The SYKOA Ch-072-17 strain is probably a new species for the genus. The results confirm the high phenotypic variability and hidden diversity among the representatives of this group of green algae.

A New Species

Based on molecular phylogenetic analyses and morphological characters, a new species from Bangladesh, northern Vietnam, and southwestern China, Leptolejeunea nigra, is described. It is mostly similar to L. balansae but remarkable for having brownish black ocelli in its leaf lobes. In the molecular phylogeny, the samples of L. nigra are not nested within any clade and form an independent lineage. In particular, the molecular dating suggested that the divergence of L. nigra happened in time span of the formation of the Himalayas.
