Re-Discovery of Myotis laniger in Hunan Province

摘要: 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。

Abstract: 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. It was identified as Myotis laniger based on morphological characteristics and molecular data of mitochondrial Cyt b and COI gene sequences. The first distribution record of this species in Hunan Province was pub- lished on October 20th, 2022. The specimen was collected in Fenghuang County, Xiangxi Prefecture. This record was the second in the province. The specimen was preserved in the Animal Collection of the College of Biology and Environmental Sciences, Jishou University.
