广西发现霍氏鼠耳蝠及印支鼠耳蝠
New record of Myotis horsfieldii and M.indochinensis in Guangxi Zhuang Autonomous Region,China
摘要
Abstract
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.关键词
