贵州分布长肢林蛙种组物种一新记录——徂徕林蛙

A New Record Species of Rana longicrus Species Group in Guizhou, Rana culaiensis

2018年5月,在贵州省黄平县朱家山县级自然保护区进行本底资源调查时采集到蛙属Rana物种标本10号,结合形态鉴定和分子系统学分析,确认该物种为徂徕林蛙Rana culaiensis,为贵州省两栖动物新记录。此次发现对于进一步认识徂徕林蛙的形态特征及地理分布格局具有重要意义。此次采集标本与模式产地标本在体型、趾间蹼等方面存在差异,这种差异是否为适应不同的地理环境而产生的形态变异,还有待采集符合统计学的标本数据来论证。

In May 2018, 10 specimens of Rana culaiensis were collected during the investigation of animal species diversity and resources in the Zhujiashan Nature Reserve, Huangping county, Guizhou province. A new record for amphibians in Guizhou province was identified based on morphological and genetic evidences. The discovery of the frog in Guizhou province is of great significance for understanding the morphological characteristics and geographical distribution pattern of this species. The Guizhou specimens of R. culaiensis differ from the specimens of type locality in body size and toe webs. Whether these morphologically differences are due to the adaptation to different geographical environments still needs to be further studied by collecting more specimen data.
