| 中文摘要: |
| 2016年8月27日晚间在湖南省衡东县四方山国有林场仙妃洞（26°58′25″N，113°3′23″E，海拔463 m）利用雾网采集到2号鼠耳蝠标本（HUNNU16SF16雄性、HUNNU16SF38雌性）。通过外部形态以及Cyt b序列比对，确认这两只鼠耳蝠为东亚水鼠耳蝠（Myotis petax）。此2个体体型较小，头体长分别为49.76 mm与49.93 mm，前臂长分别为40.73 mm和42.40 mm；头骨较小、略低而不显圆滑，上颌向上中等弯曲约30°，脑颅较低，顶部平缓，矢状脊不明显，吻较发达，宽度超过眶间宽，颧弓纤细，宽度明显超过后头宽，头骨后部略显浑圆而稍外凸；阴茎骨较长，1.088 mm，宽度为0.742 mm。此记录为湖南省翼手目分布新记录，标本保存于湖南师范大学脊椎动物标本馆。 |
| 英文摘要: |
| Two bats (sample number are HUNNU16SF16 male and HUNNU16SF38 female) have been captured by mist net in Xianfei Cave (26°58′25″N, 113°3′23″E, altitude 463 m), Sifang Mountain, Hengdong County, Hunan Province. The bats were identified as Myotis petax based on its external morphology, skull characteristics and molecular data. The measurement of forearm length was 40.73 mm and 42.40 mm for male and female which is slightly longer than that of M. petax captured from other locations (Table 2). The baculum Length in M. petax is 1.088 mm, nearly twice as large as in M. daubentonii. Maximum Likelihood tree based on Cyt b sequences was constructed (Fig. 4). The cladogram indicated the sequence of the samples from Hengdong County form a clade with M. petax that collected from Jilin Province China, Russia and Japan. The bat is a new record of Chiroptera in Hunan province. The samples were preserved in Hunan Normal University Vertebrate Specimens Museum. |
