摘　　要：2021年10月8日和2022年5月18日,于浙江省丽水市龙泉市剑池街道石武村(119°09′38″E,28°04′59″N,海拔225 m)和兰巨乡炉岙村(119°12′25″E,27°55′25″N,海拔933 m)分别采到1条小型蛇类。这2号标本在形态上与德化脊蛇(Achalinus dehuaensis)相近;在基于线粒体COI基因片段构建的脊蛇属系统发育树上,它们与德化脊蛇正模标本(采集号:YBU 13013)以高支持率(92%)聚为单系,与德化脊蛇正模标本间的未校正遗传距离为3.19%,小于脊蛇属物种间的未校正遗传距离(4.47%~23.34%)。因此,结合形态和分子数据,将其鉴定为闪皮蛇科(Xenodermidae)脊蛇属的德化脊蛇,系浙江省爬行动物分布新记录种,标本现保存在安徽师范大学标本馆(馆藏号:ANU20230018和ANU20230019)。Two small snakes were respectively collected in Shiwu Village(119°09′38″E,28°04′59″N,altitude 225 m),Jianchi Streetand,and Lu’ao Village(119°12′25″E,27°55′25″N,altitude 933 m),Lanju Town,Longquan,Lishui City,Zhejiang Province,China on October 8,2021 and May 18,2022.They are similar to Achalinus dehuaensis in morphology,with some slight differences in the type specimens.The snout-vent length and the tail length are longer than the type specimens.Twenty-one mitochondrial COI gene sequences of the genus Achalinus from GenBank were selected.Fimbrios klossi(Smith,1921)and Parafimbrios lao(Teynié,David,Lottier,Le,Vidal&Nguyen,2015)were chosen as outgroups.On the phylogenetic tree,the two newly collected samples clustered together with the holotype of A.dehuaensis(Voucher Number:YBU 13013)with high support(92%).The uncorrected pairwise distance between the two samples and the holotype of A.dehuaensis are 3.19%,less than those between the species of Achalinus(4.47%﹣23.34%).The newly collected specimens are identified to A.dehuaensis based on morphological and genetical data.It is a new record species of reptiles in Zhejiang Province.The specimens are deposited at the Anhui Normal University(Voucher number:ANU20230018 and ANU20230019).
