摘要
2021年7月,在贵州黔西南布依族苗族自治州望谟县蔗香镇(106°09′15″E,24°59′36″N,海拔485 m)采集到蛇亚目(Serpentes)眼镜蛇科(Elapidae)环蛇属(Bungarus)物种1个体.经形态特征比较,与金环蛇(B.fasciatus)鉴别特征一致;基于线粒体Cyt b基因片段构建的环蛇属部分物种系统进化发育树显示,本次采集标本与广东和云南的金环蛇标本聚为一支(0.99/96,贝叶斯法/最大似然法),它们之间的遗传距离为0.2%~0.9%.结合形态特征和系统发育分析比较,确定该标本为金环蛇,系贵州省蛇类分布新记录种.
Abstract
In July 2021,a snake specimen belonging to the genus Bungarus was collected from Zhexiang Town,Wangmo County,Guizhou Province(106°09′15″ E,24°59′36″ N,altitude 485 m).After detailed morphological comparison and molecular systematic analysis,the specimen was identified as B.fasciatus,which is a new snake record in Guizhou Province,China.Morphologically,we mainly compared diagnosis characters and measurement data(Fig.1).Phylogenetically,we constructed Bayesian inference(BI)and maximum likelihood(ML)phylogenetic trees based on mitochondrial Cyt b gene sequences.The ML and BI trees presented almost consistent topology,both showed that the new specimen from Guizhou was clustered with the B.fasciatus form Guangdong and Yunnan Provinces(0.99/96,BPP/BSP)(Fig.2),and the genetic distance between them were from 0.2%to 0.9%.
