    A new species of rain-pool frog (Dicroglossidae: Fejervarya) from western Thailand
    Chatmongkon Suwannapoom, Zhi-Yong Yuan, Ke Jiang, Fang Yan, Wei Gao, Jing Che
    Zoological Research. 2017, 38 (5): 243-250.   DOI: 10.24272/j.issn.2095-8137.2017.043
    Abstract ( 3 )   RICH HTML PDF (4610KB) ( 70 )
    We describe a new species, Fejervarya muangkanensis sp. nov., based on a series of specimens collected from Ban Tha Khanun, Thong Pha Phum District, Kanchanaburi Province, Thailand. The new species is easily distinguished from its congeners by morphological and molecular data, and can be diagnosed by the following characters: (1) small size (adult male snout-vent length (SVL) 33.5 mm; female SVL 40.0-40.9 mm); (2) tympanum small, discernible but unclear; (3) poorly developed toe webbing; (4) no lateral line system in adults; (5) characteristic "Fejervaryan" lines present in females; and (6) femoral glands absent. Molecular phylogenetic analysis of mitochondrial 16S rRNA further supports it as a distinct lineage and distinguishes it from its congeners for which sequences are available.

    A new species of the Southeast Asian genus Opisthotropis (Serpentes: Colubridae: Natricinae) from western Hunan, China
    Jin-Long Ren, Kai Wang, Ke Jiang, Peng Guo, Jia-Tang Li
    Zoological Research. 2017, 38 (5): 251-263.   DOI: 10.24272/j.issn.2095-8137.2017.068
    Abstract ( 4 )   RICH HTML PDF (7680KB) ( 329 )
    A new species of natricine snake of the Southeast Asian genus Opisthotropis Gü nther, 1872 is described from western Hunan Province of China based on both mitochondrial DNA and morphological data. The new species is morphologically most similar and genetically most closely related to O. cheni Zhao, 1999 and O. latouchii (Boulenger, 1899), but possesses considerable genetic divergence (p-distance 5.1%-16.7%) and can be differentiated from all other congeners by a combination of the following morphological characters: (1) body size large (total length 514-586 mm) and strongly built; (2) dorsal scale rows 17 throughout, feebly keeled anteriorly and moderately keeled posteriorly; (3) ventral scales 147-152, subcaudal scales 54-62; (4) preocular absent, loreal elongated and touching orbit; (5) supralabials 8-9, fifth and sixth entering obit; (6) anterior temporals short, length 1.74-2.04 times longer than width; (7) maxillary teeth subequal, 28-30; (8) dorsal surface of head with distinct irregular yellow stripes and markings edged with ochre; (9) body with clear black and yellow longitudinal streaks, partly fused to several lighter patches or thicker stripes anteriorly; and (10) venter pale yellow, with asymmetric blackish speckles along outer margin. We present an updated diagnostic key to all members of the genus Opisthotropis, and recommendations on the ecological study for the group are provided.

    Bird diversity in northern Myanmar and conservation implications
    Ming-Xia Zhang, Myint Kyaw, Guo-Gang Li, Jiang-Bo Zhao, Xiang-Le Zeng, Kyaw Swa, Rui-Chang Quan
    Zoological Research. 2017, 38 (5): 264-280.   DOI: 10.24272/j.issn.2095-8137.2017.059
    Abstract ( 1 )   RICH HTML PDF (10336KB) ( 210 )
    We conducted four bird biodiversity surveys in the Putao area of northern Myanmar from 2015 to 2017. Combined with anecdotal information collected between 2012 and 2015, we recorded 319 bird species, including two species (Arborophila mandellii and Lanius sphenocercus) previously unrecorded in Myanmar. Bulbuls (Pycnonotidae), babblers (Timaliidae), pigeons and doves (Columbidae), and pheasants and partridges (Phasianidae) were the most abundant groups of birds recorded. Species richness below 1 500 m a. s. l. was higher than species richness at higher elevations. Our results suggest that the current protected areas in this region should be expanded to lower elevations to cover critical conservation gaps.

    Myanmarorchestia victoria sp. nov. (Crustacea, Amphipoda, Talitridae), a new species of landhopper from the high altitude forests in Myanmar
    Ya-Mi Zheng, Zhong-E Hou
    Zoological Research. 2017, 38 (5): 281-290.   DOI: 10.24272/j.issn.2095-8137.2017.067
    Abstract ( 2 )   RICH HTML PDF (6023KB) ( 144 )
    Myanmarorchestia victoria sp. nov. is described from high altitude habitats in Myanmar. The new species differs morphologically from its congeners by palp of maxilliped narrow; sexually dimorphic gnathopod Ⅱ, propodus of male chelate and propodus of female mitten-shaped; and dimorphic uropod Ⅱ, outer ramus of male with small teeth distally, outer ramus of female with three distal spines. Analysis of DNA barcode sequences and niche distinctiveness support recognition of the new species.

    A new species of sisorid catfish of the genus Exostoma from the Salween drainage, Yunnan, China
    Xiao-Yong Chen, William J. Poly, David Catania, Wan-Sheng Jiang
    Zoological Research. 2017, 38 (5): 291-299.   DOI: 10.24272/j.issn.2095-8137.2017.065
    Abstract ( 4 )   RICH HTML PDF (936KB) ( 210 )
    A new species of the sisorid catfish genus Exostoma Blyth, 1860 was collected from two hill-stream tributaries of the Nujiang (Salween River) drainage in Gaoligong Mountain, south-western Yunnan Province, China from 2003 to 2006 and from two tributaries of the Salween River in Cangyuan County, Lingcang Prefecture, Yunnan Province, China (in 2007) and in Yongde County, Lingcang Prefecture, Yunnan Province, China (in 2015). Exostoma gaoligongense sp. nov. is the 10th species of the genus and is most similar to E. vinciguerrae in morphology but can be distinguished by pelvic fin reaching anus vs. not reaching; maxillary barbels just reaching or slightly surpassing pectoral-fin origin vs. surpassing pectoral-fin origin or even reaching posterior end of gill membrane; abdominal vertebrae 23-25 vs. 25-27; length of dorsal fin/dorsal to adipose distance 90.3%-287.0% vs. 59.2-85.7. A key to Exostoma spp. is provided.

Tor yingjiangensis Chen et Yang 2004, Tor qiaojiensis Wu et al. 1977, Garra qiaojiensis Wu et al. 1977, Garra bispinosa Zhang 2005, and Schizothorax oligolepis Huang 1985, originally described from the upper Irrawaddy (Ayeyarwaddy) River in China, are first reported herein as new records to Myanmar. Counts, measurements, descriptions, photographs, and distributions of the specimens of the five newly recorded species are provided.

    Complete mitochondrial genome of the leaf muntjac (Muntiacus putaoensis) and phylogenetics of the genus Muntiacus
    Guo-Gang Li, Ming-Xia Zhang, Kyaw Swa, Kyaw-Win Maung, Rui-Chang Quan
    Zoological Research. 2017, 38 (5): 310-316.   DOI: 10.24272/j.issn.2095-8137.2017.058
    Abstract ( 2 )   RICH HTML PDF (379KB) ( 71 )
    The leaf muntjac (Muntiacus putaoensis) is an endemic deer species found in the east trans-Himalayan region. In recent years, population numbers have decreased due to heavy hunting and habitat loss, and little genetic data exists for this species, thus our knowledge of distribution rangs and population sizes likewise remain limited. We obtained mtDNA genes and the complete mitochondrial genome sequence of M. putaoensis using PCR, followed by direct sequencing. The complete mitogenome sequence was determined as a circular 16 349 bp mitochondrial genome, containing 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and one control region, the gene composition and order of which were similar to most other vertebrates so far reported. Most mitochondrial genes, except for ND6 and eight tRNAs, were encoded on the heavy strand. The overall base composition of the heavy strand was 33.1% A, 29.3% T, 24.2% C, and 13.4% G, with a strong AT bias of 62.4%. There were seven regions of gene overlap totaling 95 bp and 11 intergenic spacer regions totaling 74 bp. Phylogenetic analyses (ML and BI) among the Muntiacus genus based on the sequenced of mitogenome and ND4L-ND4 supported M. putaoensis as a member of Muntiacus, most closely related to M. vuquangensis. However, when analyses based on cyt b included two more muntjacs, M. truongsonensis was most closely related to M. putaoensis rather than M. vuquangensis, and together with M. rooseveltorum, likely forming a M. rooseveltorum complex of the species. This study will help in the exploration of the evolutionary history and taxonomic status of the leaf muntjac, as well as its protection as a genetic resource.
