Re-Discovery of Myotis laniger in Hunan Province

2022年7月21日，在湖南省吉首市堂乐洞(109？39'2\"E，28？18'9\"N，海拔337 m)采集到1只体型较小的鼠耳蝠(♂)。该蝠前臂长35.4 mm，后足长超过胫长之半；颅全长14.66 mm，头骨略低而不显圆隆，顶部平缓；齿式2.1.3.3/3.1.3.3 = 38。综合形态特征与线粒体Cyt b和COI基因序列的分子数据分析，将其鉴定为华南水鼠耳蝠(Myotis laniger)。该蝠种在湖南省的首次分布记录是2022年10月20日发表的，标本采于湘西州凤凰县境内。本次华南水鼠耳蝠雄性个体的发现是在湖南省境内的再次分布记录，标本保存于吉首大学生物资源与环境科学学院动物标本室。
An identification was needed for one small-typed specimen of Myotis (♂) collected in the cave of Tangle (109？39'2\"E, 28？18'9\"N, 337 m ASL), Jishou City, Hunan Province, on July 21st, 2022. The specimen had some diagnostic features as follows: Forearm length was 35.4 mm; the hindfoot length was more than half of tibiae; the total length of skull was 14.66 mm; the skull was slightly lower without round carina, and the top gentle; dental formula 2.1.3.3/3.1.3.3 = 38.
