云南省两栖类新属纪录——越南姬蛙属

Vietnamophryne(Amphibia: Anura: Microhylidae), a Newly Recorded Genus of Frog in Yunnan Province

2019年7月,在中国云南省红河哈尼族彝族自治州屏边苗族自治县大围山国家级自然保护区采集到两栖纲无尾目姬蛙科(Günther 1858)标本一号。该标本体型较小,头体长为16.8 mm。背部皮肤整体呈砖红色,有微微凸起的微小白色疣粒散布于背部、侧腹和后肢背部;吻部至颞部为黑褐色,掺杂有少量白色斑块,手指第一指很短等形态特征与Vietnamophryne orlovi(Nikolay 2018)的形态特征一致。基于16S rRNA基因片段的系统发育分析结果显示,本研究的样本与V.orlovi聚在一支,遗传距离较小,为0.9%(Kimura−2−Parameter),确定该标本是V.orlovi,为中国新属记录,将其中文名记录为“越南姬蛙属”,该物种的中文名记录为“奥氏越南姬蛙”。

In July 2019,a specimen from Microhylidae(Günther 1858)was collected from Dawei Mountain,Pingbian National Nature Reserve,Honghe Prefecture,Yunnan Province,China.The specimen was small in size(SVL=16.8 mm),dorsum brick red,with tiny white tubercles on dorsum,flanks and dorsal hindlimbs;dark brown snout-temple region with minimum white patches;first finger reduced to nub or shortened,as consistent to descriptive morphology of Vietnamophryne orlovi(Nikolay 2018).Molecularly,newly collected specimen clustered with V.orlovi,with a low genetic distance(K−2−P distance=0.9%)by phylogeny stood on 16S rRNA.Additionally,this study firstly suggested‘越南姬蛙属'as Chinese common name of genus Vietnamphryne,while the Chinese common name of V.orlovi as‘奥氏越南姬蛙',yielded to a new genus record in China.
