| 中文摘要: |
| 2020年10月17日，在甘肃省卓尼县（103°30′37″ E，34°35′00″ N，海拔2 540 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。 |
| 英文摘要: |
| 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. |
