摘　　要：2016年10月和2018年7月,本研究组在贵州省榕江县和荔波县开展翼手目调查时,使用蝙蝠竖琴网捕获6只管鼻蝠(5♂,1♀),采用传统形态学和分子系统发育学方法对其进行物种鉴定.这些标本体型中等偏小,前臂长28.42~33.38 mm,毛发蓬松,整体呈淡红褐色;头骨两侧鼻骨微微向上隆升,中间有凹陷,侧视图中第2上门齿将第1上门齿完全遮挡,上犬齿高于第2前臼齿,第2前臼齿高于第1前臼齿,第1上臼齿和第2上臼齿都无中齿尖,其形态特征和度量数据均与圆耳管鼻蝠(Murina cyclotis)相符.同时,线粒体细胞色素氧化酶亚基Ⅰ基因(mitochondrial cytochrome oxidase subunit Ⅰ gene,COI)和核基因重组激活基因2(recombination activating gene 2,RAG2)构建的分子系统发育树,均支持上述标本为圆耳管鼻蝠,为该种在贵州省分布的首次记录.迄今,圆耳管鼻蝠在国内分布区为贵州、江西、广东、广西和海南等地.In August 2016 and July 2018, a series of chiropteran surveys were carried out in Libo Country and Rongjiang Country, Guizhou Province, China. Using harp trap six tube-nosed bats were sampled(5♂,1♀). They are small-medium sized individuals with the reddish-brown fur and forearm length ranging from 28.42 to 33.38 mm. The rostral profile is relatively long with a well-defined concavity in the interorbital region. In lateral view of skull, the second upper incisor is completely covered by the first one, the upper canine exceeds the second premolar which is higher than the first one. Mesostyle of first and second upper molars is absent. All the external and craniodental characteristics accord with Murina cyclotis. Such identifications are further verified by our molecular phylogenetic inferences using mitochondrial genes COI(mitochondrial cytochrome oxidase subunit Ⅰ gene, COI) and nucleus genes RAG2(recombination activating gene 2,RAG2). This finding indicates a new chiroptera record in Guizhou Province, China. Thus far, M. cyclotis from China is recorded in Guizhou, Jiangxi, Guangdong, Guangxi and Hainan island.
