摘　　要：西南鼠耳蝠（Myotis altarium Thomas,1911）,因峨眉山为其模式产地,又称峨眉鼠耳蝠或者四川鼠耳蝠。隶属于翼手目（Chiroptera）蝙蝠科（Vespertilionidae）鼠耳蝠属（Myotis）,A new record of Myotis altarium was found in Guangdong Province when a survey was conducted in Nanling National Nature Reserve in September 2009. Its features are described in detail and compared with the original description. Comparisons between its morphological measurement data and published data,as well as the analytical results of its karyotype （ 2n = 44,FN = 50） ,it can be identified as Myotis altarium. In this study,echolocation calls of Myotis altarium were found to be frequency modulated and of short pulse duration. We also found that the maximum frequency and pulse duration in holding status and flying status are greatly different.
