草原须鼠耳蝠在中国西北三省区新分布
New records of Myotis aurascens in three northwest provincial regions of China
摘要
Abstract
In August 2023,40 specimens of Myotis bat(29 males and 11 females)were captured by using harp traps and mist nets in Xinjiang,Qinghai,and Ningxia provinces,northwest China.The specimens were morphologically identified as Myotis aurascens based on the short dorsal hairs,fur on back brown,belly fur dark gray at roots,and gray white at tips;head and body length(40.4±2.7)mm;forearm length(35.1±1.3)mm;ear length(13.6±1.1)mm;tragus slen-der and straight(6.9±0.7)mm,approximately half the length of the ear pinna;hindfoot length less than half of the tibia length;greatest length of skull(13.71±0.39)mm;condylobasal length(12.94±0.48)mm;dental formula 2.1.3.3/3.1.3.3=38 teeth.Based on phylogenetic analysis of Cyt b gene,the captured samples in this study were clustered to-gether with Myotis aurascens from Inner Mongolia of China and Republic of Korea as one clade with posterior probabili-ty 1.00.These specimens represent the first record of Myotis aurascens to these three provinces in northwest China.This study expands the range records of this species and provides basic data for a deeper understanding of bat diversity.关键词
