摘　　要：2020年10月17日,在甘肃省卓尼县(103°30′37″E,34°35′00″N,海拔2540 m)用手网采集到1只雌性蝙蝠;该个体前臂长59.98 mm;两耳宽大,耳缘具毛,双耳前缘基部在额顶相联;吻部突出,上唇肥厚有褶皱;尾从尾膜后缘伸出一半;足掌具明显可见肉垫;各脚趾缘具有白色硬毛;背毛呈土褐色,毛基苍白色。头骨狭长,颅全长24.05 mm;颧弓平直;上门齿与上犬齿大,下门齿小,齿式为1.1.2.3/3.1.2.3=32。以上形态特征均与宽耳犬吻蝠(Tadarida insignis)相符;基于细胞色素b基因(Cyt b)系统发育学证据也支持上述结果,故将此标本鉴定为宽耳犬吻蝠。此为该种在甘肃省翼手目分布新记录。On October 17th 2020,one female bat was collected by handheld-netting from Zhuoni Country,Gansu Province(103°30′37″E,34°35′00″N).Its forearm length is 59.98 mm;ears are large and connect at the anterior bases;tragus fringed with hair anteriorly and dorsally;upper lip is wrinkled;muzzle projects beyond upper lip;terminal half tail extended beyond the membrane;feet are of a distinct fleshy pad;toe edges with white bristles;dorsal fur is black-gray and paler at base.The skull is elongated with a greatest length of skull(GTL)of 24.05 mm;zygomatic arch is straight;its upper incisors and upper canines are large,while lower incisors are small.Its dental formula is 1.1.2.3/3.1.2.3=32.All characteristics mentioned above are consistent with the East Asian Free-tail Bat(Tadarida insignis).Such identification is also supported by phylogenetic evidence based on Cytochrome b gene segment(Cyt b).The finding represents the first chiropteran record of T.insignis in Gansu Province,China.
