摘　　要：鼠耳蝠(Myotis)是蝙蝠科(Vespertilionidae)中种类最多的类群之一,全世界共有100余种(Wilson and Mittermeier,2019),中国分布有27种,其中在广西分布有7种(魏辅文等,2022)。本研究组于2023年5—6月调查广西翼手目资源期间,使用手抄网捕获7只蝙蝠,其中4只体型中等偏小(标本号:GIZ230833♀、GIZ230849♀、GIZ230896♂、GIZ232309♂),结合形态学与分子系统学进行物种鉴定,为霍氏鼠耳蝠(Myotis horsfieldii);另外3只体型中等(标本号:GIZ231087♀、GIZ231088♂、GIZ231089♀),经鉴定,为印支鼠耳蝠(M.indochinensis),皆为广西蝙蝠分布新记录种。During a investigation of Chiroptera diversity in Guangxi Zhuang Autonomous Region,seven Myotis bats(3 males and 4 females)were captured from May to June,2023 in Tuoqi water conservancy tunnel,Youliaogu water conser‐vancy tunnel,and G80 culvert in Tianyang District,and in Lilangtun tunnel in Leye County,all in Baise City,Guangxi Zhuang Autonomous Region.The species of the aforementioned specimens were identified using a combination of tradi‐tional morphological methods and molecular phylogenetic analysis.Among the captured specimens,four bats were small to medium size,with forearm lengths of 33.7−37.4 mm.The dorsal hairs are dark brown to black,with light gray on the abdominal hair tips near the tail,and the wings are a uniform dark brown.The skull is long and narrow,with a robust snout,relatively flat skull roof,and delicate cranial bones,with a noticeable slope at the frontal bone.These morphological characteristics and measurements are consistent with Myotis horsfieldii.The other three bats were medi‐um-sized,with forearm length of 45.2−45.5 mm.The dorsal hairs are long and dark brown,with light yellow-brown tips on the abdominal hairs,and the wings are of a single color and attach at the base of the first toe.The skull is massive with a broad and short rostrum;the cranial profile is flattened.Zygomata are strong,and the sagittal and lambdoid crests are well pronounced.The morphological characteristics and measurements are consistent with those of Myotis indochi‐nensis.Phylogenetic analysis based on the Cyt b gene also supported the above morphological identification results.This report represents a new distribution record of M.horsfieldii and M.indochinensis in Guangxi Zhuang Autonomous Region.The specimens are kept in the Institute of Zoology,Guangdong Academy of Sciences.
