文摘2023年4月21日,在湖南南山国家公园开展野生动物多样性调查过程中,于白云湖(26°18′36.23″N,110°20′05.43″E;海拔606 m)采集到2号蛙类标本(1雌1雄),经初步形态鉴定,其与桂北琴蛙(Nidirana guibeiensis)特征相似。对采集标本的线粒体16S r RNA进行PCR扩增测序后,构建琴蛙属(Nidirana)部分物种贝叶斯系统发育树,结果显示该蛙类标本与桂北琴蛙聚为一支,且具有较高的支持率(1.00);基于Kimura双参数模型估算,该标本与广西兴安县采集的桂北琴蛙标本间的遗传距离为0,远小于琴蛙属不同种间的遗传距离(3.2%~8.7%)。经形态特征鉴定和系统发育分析,确定该蛙类标本为无尾目(Anura)蛙科(Ranidae)琴蛙属(Nidirana)桂北琴蛙,为湖南省两栖动物新记录种。
