The original locality of these specimens is known only as “China”, and further details are not known. Morphologically, this species differs from all other congeners in the combination of coloration, body size, snout length, head width, tail length and width, and length of upper jaw tooth series and vomerine tooth series. Genetically, this species is separated from all other congeners by substantial genetic distances in mitochondrial DNA sequences.

The generic allo- cation of the new species is based on morphological and molecular characters. In morphology, it is most similar to Paramesotriton chinensis but differs in having distinct gland emitting a malodorous secretion (here named scent gland), a postocular stripe, and two non-continuous, dorsolateral stripes on the dorsolateral ridges. Furthermore, neoteny was observed in most individuals of the new species. This has not been previously reported to occur in any other species of Paramesotriton. Analysis of our molecular data suggests that this species a third major evolutionary lineage in the genus Paramesotriton. Key words: Caudata; Salamandridae; Paramesotriton zhijinensis; new species; scent gland; Guizhou; China Introduction Guizhou Province, located in the southwestern mountainous region of China, is known for its rich amphibian faunal diversity (Liu and Hu 1961). During recent surveys of the Guizhou herpetofauna (July, September, and November, 2006; January and September, 2007), we collected salamanders superficially resembling Parame- sotriton chinensis (Gray).

Stinson1,2,* and Stephen M. Deban2 ABSTRACT salamanders with more robust and mineralized hyobranchial Salamanders use the hyobranchial apparatus and its associated apparatus produce greater fluid velocity during suction-feeding musculature for tongue projection on land and for suction feeding in events (Özeti and Wake, 1969; Miller and Larsen, 1989; Stinson and water. Hyobranchial apparatus composition and morphology vary Deban, 2017). Our understanding of the direct effects of across species, and different morphologies are better suited for morphology on terrestrial feeding performance, and the trade-offs feeding in aquatic versus terrestrial environments. We hypothesize that may accompany feeding across aquatic and terrestrial that differences in hyobranchial morphology result in functional trade- environments, however, is limited (Beneski et al., 1995; Larsen offs in feeding performance. We predict that semi-aquatic and aquatic et al., 1996, 1989; Miller and Larsen, 1990). In this study, we salamandrids with hyobranchial morphology suited for aquatic compared the morphology and tongue-projection performance of feeding will have lower performance, in terms of tongue-projection terrestrial, semi-aquatic and aquatic salamandrids to assess distance, velocity, acceleration and power, compared with terrestrial

This new species is distinguished from its congeners by a combination of morphological and molecular characters. In morphology, it is chra- cterized by distinctive irregular bluish grey spots on the dorsum from head to tail; irregular, bright orange blotches on venter, chin, underside of axillae, limbs, cloaca; one bright orange stripe in the middle of venter; and ventral tail orange red. Analyses of mitochondrial DNA data indicate that this new species forms one highly diverged lineage within the Chinese group of Cynops. Keywords Caudata, Salamandridae, Cynops glaucus sp. nov., newt, Guangdong, molecular analysis 1. Introduction and more thorough fieldwork in remote montane regions of southern China, suggest that the true species richness of The salamandrid genus Cynops, commonly known as the modern Asian newts is probably grossly underestimated fire-bellied newts, ranges from Yunnan in southwestern (Gu et al., 2012; Li et al., 2008a, 2008b; Nishikawa et al., China to Japan in East Asia.

    Asian Herpetological Research 2012, 3(2): 83–102 DOI: 10.3724/SP.J.1245.2012.00083 Comparative Osteology of the Genus Pachytriton (Caudata: Salamandridae) from Southeastern China Yunke WU1, Yuezhao WANG2* and James HANKEN1 1 Museum of Comparative Zoology and Department of Organismic and Evolutionary Biology, Harvard University, Cambridge 02138, Massachusetts, USA 2 Chengdu Institute of Biology, Chinese Academy of Sciences, Chengdu 610041, Sichuan, China Abstract Osteological evidence provides invaluable insights into patterns of amphibian biodiversity. In small montane streams of southeastern China, an endemic genus of salamanders (Pachytriton) displays remarkable aquatic specializations, many of which are reflected in skeletal morphology, but these specializations remain to be studied in an integrated perspective. Attempts to fully resolve the taxonomy within the genus also can benefit from knowledge of internal morphology. We present a detailed description of the adult skeleton of P. brevipes, P. inexpectatus and P. archospotus by analyzing both cleared-and-stained and radiographed specimens in a comparative framework. Compared to terrestrial and amphibious salamanders, the most distinctive osteological features of Pachytriton include a modified hyobranchial apparatus, a reduced frontosquamosal arch, and deep neural and haemal arches of the caudal vertebrae. The hyobranchial apparatus of P. archospotus is distinctly different from that of congeners and likely secondarily derived. Patterns of interspecific variation suggest that northeastern P. inexpectatus is more closely related to P. brevipes than it is to southwestern P. inexpectatus, thereby reinforcing results from earlier molecular phylogenetic analyses. We advocate assigning northeastern P. inexpectatus to P. brevipes. Keywords montane amphibian, anatomy, aquatic specialization, interspecific variation, taxonomy 1.

Bayesian ancestral state reconstructions of salamander life cycle modes and body form metrics. Life cycle was reconstructed using BayesTraits [S1] and the three modes were treated as ordered categorical states: paedomorphic (pd), biphasic (bi), and direct development (dd). Median Trunk Vertebral Number (Vert) and median Adult Body Forms (ABF) including 95% confidence intervals were reconstructed in StaBleTraits [S2].
