A New Species of the Genus Rhacophorus (Anura： Rhacophoridae) from Dabie Mountains in East China

A new species of rhacophorid of the genus Rhacophorus is described from the Dabie Mountains of west Anhui, east China. The new species, Rhacophorus zhoukaiyae sp. nov. is distinguished from its congeners by a combination of the following characters： 1） the ventral surface and front-and-rear of the femur is paler yellowish and decorated with irregular grayish blotching, and without obvious spots on the dorsum of the hand and foot webbing; 2） the outer metatarsal tubercle is small; 3） outer fingers are half-webbed and outer toes two third webbed; 4） the skin on the dorsum is smooth and without compressed warts; 5） the throat, chest and belly are pure paler yellowish; 6） the dorsal part of the fingers and toes are grayish-white; 7） the iris is golden-yellow. In addition, the phylogenetic tree showed that all the individuals of R. zhoukaiyae sp. nov. clustered into one distinct clade which suggested the validity of this species. This results could also be used to the support of species delimitation. Currently, this species is known only from mid-elevation montane evergreen forest in the Dabie Mountains of west Anhui, China.

Catalogue of the Type Specimens of Amphibians and Reptiles in the Herpetological Museum of Chengdu Institute of Biology, Chinese Academy of Sciences: I. Rhacophoridae(Anura, Amphibia)

In order to facilitate herpetological research for all the herpetologists both in and outside of China, we will report all the type specimens of amphibia and reptilia deposited in the Herpetological Museum of Chengdu Institute of Biology(CIB), Chinese Academy of Sciences in series. This report focuses on the family Rhacophoridae of Anura in Amphibia, including 13 species. The contents of the report include synonym lists and generic transfer of type species, measurements of type specimens, particularly for those with no previously published measurement data, and chromosomal data for each species.

Theloderma licin McLeod and Ahmad,2007 (Lissamphibia:Anura:Rhacophoridae),a New Frog Record for Borneo

A new record of the rhacophorid frog, Theloderma licin is reported from Gunung Serambu, in the Bau region of western Sarawak, East Malaysia, which comprises the first published record of the species from the Sundaic island of Borneo. The species was previously known from the Malay Peninsula （southern Peninsular Thailand and Peninsular Malaysia）. Species of Theloderma are widespread in mainland and insular Southeast Asia, their arboreal habits perhaps contributing to our perception of rarity.

A New Species of Gracixalus (Anura： Rhacophoridae) from West Guangxi, China

We discovered a new species of the genus Gracixalus, Gracixalus tianlinensis sp. nov. which is morphologically almost similar to G. jinggangensis, G. jinxiuensis and G. sapaensis, but is distinguished from these species and all other rhacophorids in China and adjoining countries by a combination of the following characters： （1） SVL 30.3-35.9 mm in male, 35.6-38.7 mm in female, （2） head length less than head width, （3） vomerine teeth absent, （4） supratympanic fold distinct, （5） axilla and posterior surface of flanks pale yellow, （6） nuptial pads distinct on Finger I and slightly visible on Finger II, （7） dorsum brown to beige, with an inverse Y-shaped dark brown marking, （8） single subgular vocal sac. Our preliminary phylogenetic analyses implied G. tianlinensis sp. nov. is sister to G. sapaensis with well-supported values. Currently, this new species is known to be distributed in montane evergreen forests in association with montane bamboo in Cenwanglaoshan National Nature Reserve, Tianlin County, Guangxi, China.

Characterization and Phylogenetic Implications of the Complete Mitogenomes of Two Species in the Genus Zhangixalus(Anura:Rhacophoridae)

Mitochondrial genomes(mitogenomes)in frogs are essential for reconstructing the phylogenetic relationships and shedding light on the molecular evolution in these animals.However,there are only seven complete Rhacophoridae genomes that have been reported to date.In this paper,two complete mitogenomes of the Chinese whipping frog(Zhangixalus chenfui)and Emei tree frog(Z.omeimontis)were described,each of which was 20520 and 19782 bp in size,and had A+T contents of 64.26%and 63.83%.The two mitogenomes each included two non-coding control region(D-loop,CR),two ribosomal RNA genes(rRNAs),13 protein-coding genes(PCGs),and 22 transfer RNA genes(tRNAs),and it was found that the mitogenome of Z.chenfui also includes three tandem tRNAMet gene sequences.A typical clover-leaf structure was found for all tRNAs except for tRNASer1(AGN),which showed a reduced DHU arm.The putative D-loop region contains multiple types of tandem repeats regions.Both of these two mitogenomes showed similar pattern of gene rearrangement(tRNA-Ser-ND6-tRNA-Glu-CytbCR1-ND5-CR2-tRNA-Thr-tRNA-Leu-tRNA-Pro).Additionally,three consecutive tRNAMet genes were found for the first time in Z.chenfui,a species in the Rhacophoridae family.For all phylogenetic analyses,which were based on 13 protein-coding genes from 91 Ranoidea mitogenomes,the same phylogenetic trees were observed using either maximum likelihood or Bayesian approaches.These results suggest that the phylogenetic hypotheses for the Ranoidea(including Rhacophoridae,Mantellidae,Ranidae and Dicroglossidae)derived from these mitogenomic data could provide substantiation for the relationships of(Dicroglossidae(Ranidae,(Mantellidae,Rhacophoridae))),and support the presence of a monophyletic group in four families.Moreover,Z.omeimontis and Z.dennysi were found to cluster on the same branch,indicating that they were more closely related as a group.This group may in turn form sister groups with Z.arboreus and Z.schlegelii.However,Z.chenfui is located on the base of other species in the genera.Increased mitogenome sampling should be conducted to provide a more satisfactory resolution to the phylogeny of the Rhacophorus,Rhacophoridae,and Mantellidae.

中国三种树蛙骨骼系统的比较研究

用透明骨骼双色法对斑腿泛树蛙(Polypedates megacephalus)、大树蛙(Rhacophorus dennysi)、黑点树蛙(Rhacophorus nigropunctatus)的骨骼系统进行了比较研究。结果发现黑点树蛙在副蝶骨、舌器、肩带等方面与斑腿泛树蛙和大树蛙存在着明显差异,并对泛树蛙属与树蛙属的分类进行了初步探讨。
