摘　　要：2016年4—6月在贵州梵净山国家级自然保护区(108°46′8.07″E,27°50′56.77″N,海拔539 m)和雷公山国家级自然保护区(108°11′47.2″E,26°22′42.24″N,海拔1687 m)采集到2号两栖动物标本。经形态特征比较,与武陵掌突蟾Leptobrachella wulingensis相似。基于线粒体16S rRNA基因构建的掌突蟾属Leptobrachella部分物种系统发育树显示,此次采集的标本与武陵掌突蟾聚为一支。基于Kimura双参数模型估算本次采集的标本与武陵掌突蟾模式产地标本间的遗传距离为1.6%,小于掌突蟾属物种间的遗传距离。综合形态学和系统发育比较,确定此次采集到的掌突蟾标本为无尾目Anura角蟾科Megophryidae掌突蟾属的武陵掌突蟾,系贵州省两栖动物新记录种。During the surveys in the Fanjingshan National Nature Reserve and Leigongshan National Nature Reserve of Guizhou Province,from April to June 2016,2 toad specimens were collected.We compared the specimens with other species of Leptobrachella by morphological and molecular.On morphology,the specimens resemble L.wulingensis,and phylogenetic analyses based on 16S rRNA gene sequences showed that the 2 specimens were clustered as sister to L.wulingensis.The genetic distance between our specimens and L.wulingensis from its type locality was 1.6%,lower than that between Leptobrachella species.Based on morphological and molecular comparisons,the specimens were classified as L.wulingensis,which is the new record of this species in Guizhou Province,China.
