Abstract: lery’s tube-nosed bat (Murina eleryi)is a small-sized bat that was recorded as a new species in 2009,and has external features that quite resemble the little tube-nosed bat (Murina aurata). We conducted a preliminary study on population genetic structure of M. eleryi in Guangdong with partial cytochrome oxidase subunit I (COI)of mitochondrial DNA as a molecular marker. Morphologically,we have compared these 2 species and explored the external features and taxonomic status. Results showed that (1)M. eleryi in Guangdong clustered with ‘M. aurata’and there was little difference between the species;(2)the origin of M. eleryi in south China was not monophyletic,the population genetic structure disagreed with the geographical distribution patterns,and populations in Guizhou and Gaungdong shared closer phylogenetic relationships with Vietnamese and Laotian populations than with the Guangxi population;(3)Since the external and skull similarities of M. eleryi and M. aurata as well as the lag of identification of M. eleryi, many identified ‘M. aurata’in online database (e. g. ,NCBI and BOLD)and some published papers should be M. eleryi instead.

摘要： 艾氏管鼻蝠是2009 年发表的新种,其体型较小,外形与金管鼻蝠极其相似,本文以广东采集的艾氏管鼻蝠线粒体部分COI 序列片段为分子标记,对其种群遗传结构进行了初步分析,并与金管鼻蝠形态进行比较,对2个种的外形特征及分类地位进行了探讨。结果表明: (1) 本研究获得的艾氏管鼻蝠序列与BOLD 数据库中的“金管鼻蝠”序列聚为一支,遗传差异极小; (2)华南区域艾氏管鼻蝠并非单系,其种群遗传结构与种群地理分布模式不一致,贵州、广东与越南、老挝种群的亲缘关系较广西种群更近; (3)现有数据库及国内部分研究中鉴定的“金管鼻蝠”实际应为艾氏管鼻蝠。
