摘　　要：我国分布的宽耳蝠包括北京宽耳蝠(Barbastella beijingensis)和东方宽耳蝠(B.darjelingensis)2个物种。东方宽耳蝠在我国分布于内蒙古、新疆、青海、陕西、甘肃、河南、湖南、江西、四川、重庆、云南、贵州、台湾等省(自治区、直辖市),但北京宽耳蝠仅记录于北京。2022年7月于山西省祁县昌源河湿地公园林道中(37°19′15″N,112°26′18″E,海拔812 m),采集到1只雄性宽耳蝠。该蝠体型中等,前臂长43.7 mm。双耳在额部相连,外耳廓近方形,横嵴明显,耳廓中部外缘具有较小的耳突,其第三掌骨长大于第四掌骨长大于第五掌骨长。颅全长为14.6 mm,具有强壮的上前臼齿和下前臼齿。以上特征均与北京宽耳蝠相符。头骨特征中,与北京宽耳蝠相比其具有较小的颅基长和颅宽,其余头骨测量参数值均与北京宽耳蝠相近。基于Cytb和ND1基因序列的系统发育学证据亦支持形态鉴定结果。结合外部形态、头骨参数及分子数据,将山西样本鉴定为北京宽耳蝠,为山西省翼手目分布新记录种。Two species of barbastelle live in China,Barbastella beijingensis and B.darjelingensis.B.darjelingensis is found in Inner Mongolia,Xinjiang,Qinghai,Shaanxi,Gansu,Henan,Hunan,Jiangxi,Sichuan,Chongqing,Yunnan,Guizhou,and Taiwan,while B.beijingensis has only been recorded in Beijing.A male barbastelle was captured by mist net in the forest road of Changyuanhe Wetland Park in Qi County(37°19′15″N,112°26′18″E,812 m),Shanxi Province,in July 2022.We measured the external morphology and skull characteristics of the captured sample,and amplified the Cyt b and ND1 sequences.With 1000bootstrap replicates,phylogenetic trees were reconstructed from Cyt b and ND1 gene sequences by Mega 5.0.The forearm length is 43.7 mm,and the sample had nearly square outline of ears with transverse ridges(Fig.1).Its ears joined across the forehead,and it had a small lobe on the middle outer edge of each pinna(Fig.1b,c).This Shanxi sample had a longer 3rd,a middle 4th and a shorter 5th metacarpal lengths(Table 1).The length of skull is 14.6 mm,and it has robust upper and lower premolars(Fig.2).All morphological measurements were in accord with those from Barbastella beijingensis,except condylo-base length and braincase breadth(Table 1).Cyt b and ND1 sequences from the Shanxi sample showed higher similarities to those of B.beijingensis(Cyt b:99.5%;ND1:98.6%to 100%),than to those of B.darjelingensis(Cyt b:86.3%to 86.9%;ND1:81.6%to 83.3%).The Shanxi sample clustered with B.beijingensis,rather than B.darjelingensis in both cladograms of Cyt b and ND1 genes(Fig.3).Through comparing external morphology,skull characteristics and molecular data with B.beijingensis and B.darjelingensis,this bat is identified as B.beijingensis,which is a new record for the Chiroptera in Shanxi Province.
