摘　　要：2010年8月和2018年5月于贵州省雷山县(雷公山国家级自然保护区,1号标本)、贵州省黄平县(朱家山县级自然保护区,3号标本)和麻江县(1号标本)共采集到5号游蛇科Colubridae后棱蛇属Opisthotropis标本,经形态学和分子系统学分析鉴定为赵氏后棱蛇Opisthotropis zhaoermii,这是该种在模式产地湖南省古丈县外的首次发现。线粒体cyt b序列构建的系统发育树显示,5号赵氏后棱蛇(武陵山系以西)和模式产地(武陵山系以东)的聚为一支;遗传距离计算结果显示,5号赵氏后棱蛇与模式产地的为0.08%;分子遗传学结果表明,赵氏后棱蛇分布于武陵山系东、西两侧。武陵山系的余脉(如佛顶山)对赵氏后棱蛇不同地理种群的遗传分化可能起着重要影响。A total of 5 specimens belonging to the genus Opisthotropis were collected from Leishan county(Leigongshan National Nature Reserve,1 specimen),Huangping county(Zhujiashan Nature Reserve,3 specimens)and Majiang county(1 specimen)in Guizhou province in August 2010 and May 2018.After detailed morphological comparison and molecular systematic analysis,they were identified as Opisthotropis zhaoermii.This is the first record of O.zhaoermii outside of the type locality(Guzhang county,Hunan province).The phylogenetic tree constructed based on mitochondrial cyt b sequences showed that,the samples of O.zhaoermii collected from 3 counties of Guizhou province(the west of the Wuling Mountains)and the type locality(the east of the Wuling Mountains)formed a common clade,and the genetic distance between these samples was 0.08%.The results of molecular genetics revealed that O.zhaoermii should be distributed in the west and east regions of the Wuling Mountains.The remaining mountain range of the Wuling Mountains,for example,the Foding Mountains,might have important influences on the genetic differentiation of O.zhaoermii.
