安徽黄山发现孟闻琴蛙

琴蛙属(Nidirana)是广泛分布于东洋界的两栖动物,目前安徽省琴蛙属仅记录了弹琴蛙 (N. adenopleura)1种。2022年7月在安徽省黄山地区(九龙峰自然保护区和马金岭自然保护区)采集到9号两栖动物标本,其形态特征与孟闻琴蛙(N. mangveni)相似;此外,基于线粒体COI基因片段的分子系统发育分析显示,此次采集到的琴蛙标本与孟闻琴蛙聚为一支,且具有高的支持率(贝叶斯后验概率/最大似然支持率为1.00/98%),而且和孟闻琴蛙遗传距离最近,与模式产地的孟闻琴蛙遗传距离仅有0.04%。因此,结合形态比较和分子系统学分析,鉴定此次采集的琴蛙属标本为孟闻琴蛙,为安徽省两栖动物分布新记录种。这一发现将孟闻琴蛙的分布范围扩展至皖南地区,为琴蛙属和皖南地区的生物地理学和地史研究提供了重要数据。

Nidirana mangveni Found in Huangshan, Anhui Province

The genus Nidirana is an amphibian widely distributed in the Oriental realm. Only one species (N. adenopleura) of Nidirana has been recorded in Anhui Province. In July 2022, nine specimens of Nidirana were collected in the Huangshan area of Anhui Province (Jiulongfeng Nature Reserve and Majinling Nature Reserve). Firstly, their morphological characteristics were similar to those of N. mangveni (Fig. 1, Table 2). In addition, the molecular phylogenetic analysis based on mitochondrial COI gene fragments showed that the newly collected specimens had the closest evolutionary relationships with N. mangveni with high support. Moreover, the genetic distance between the new samples and N. mangveni was the closest, with only 0.04% sequence divergence between the new samples and N. mangveni from the type locality (Table 3). Therefore, combined with morphological comparison and molecular phylogenetic analysis, the new specimens were identified as N. mangveni, which is the new amphibian record of Anhui Province, China. This discovery extends the recorded distribution range of N. mangveni to southern Anhui and provides the first-hand basic information for the biogeography of the genus Nidirana.
