    摘要:

    2022年8月,于湖南省郴州市永兴县湘阴渡镇(113°01′18′′ E,26°11′87′′ N,海拔174 m)采集到两头蛇活体标本1号,通过形态测量比较,发现所采集标本与中国广东省分布的岭南两头蛇(Calamaria arcana)形态特征基本一致;后基于线粒体Cyt b基因片段进行分子系统发育分析,结果显示该标本与岭南两头蛇形成高支持率单系群(后验概率PP为1.00,自举值BS为100),所采集标本与岭南两头蛇的遗传距离为1%。综合形态学和分子生物学证据,最终确定该标本为两头蛇科(Calamariidae)两头蛇属的岭南两头蛇,系湖南省蛇类分布新记录种。

    Abstract:

    An unidentified snake specimen was collected from a heap of sticks and dry leaves in Xiangyindu Town, Yongxing County, Hunan Province, China (113°01′18″ E,26°11′87″ N, 174 m) during a biodiversity survey in early August 2022. Morphological characteristics comparison revealed that the collected specimen was generally consistent with the morphological characteristics of the Calamariaarcana from Guangdong Province, China. Bayesian and maximum likelihood phylogenetic analyses based on the mitochondrial gene fragment Cyt b showed a high support monophyletic group between the collected specimen with the C. arcana (PP 1.00, BS 100), and the uncorrected pairwise sequence divergence was 1%. Thus, based on morphological analysis and phylogenetic comparison, this specimen was finally identified as C. arcana, which is a new snake record in Hunan Province.
