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.
