Abstract
in English, Chinese

The disk-footed bat Eudiscopus denticulus(Osgood, 1932) is a rare species in Southeast Asia. During two chiropteran surveys in the summer of 1981 and 2019, eight and three small Myotis-like bats with distinct disk-like hindfeet were collected from Yunnan Province, China, respectively. External, craniodental, and phylogenetic evidence confirmed these specimens as E. denticulus, representing a new genus in China. The complete mitochondrial genome consistently showed robust support for E. denticulus as a basal lineage within Myotinae. The coding patterns and characteristics of its mitochondrial genome were similar to that of other published genomes from Myotis. The echolocation signals of the newly collected individuals were analyzed. The potential distribution range of Eudiscopus in Southeast Asia inferred using the MaxEnt model indicated its potential occurrence along the southern border region of Yunnan, China.

盘足蝠 Eudiscopus denticulus (Osgood, 1932)为东南亚地区分布、较稀少的蝙蝠种类。于1981年和2019年夏季，在云南南部进行翼手目调查时，分别采集到8只和3只后足呈盘状的小型蝙蝠。基于外形、头骨形态和分子系统发育学证据证实，这批标本为盘足蝠，为中国翼手目属和种的分布新纪录。以线粒体基因组为标记的系统发育学结果，显示其为鼠耳蝠亚科Myotinae中的基础支系，其基因组编码模式和特征均与鼠耳蝠线粒体基因组类似。同时，课题组也对新采集的个体进行回声定位声波录制与分析。最大熵生态模型MaxEnt预测的结果显示，该物种潜在的适生区呈碎片化，云南南部边境地区均为其潜在的分布区域。.
