    摘要:

    本研究组于2013年6月和7月在甘肃平凉、宁夏固原和陕西咸阳共捕获25只宽耳蝠(野外采集号为KT13742、KT13743、KT13753、PY13770、BX13777 ~ BX13797)。上述宽耳蝠前臂长42.00 ~ 45.58 mm,后足长小于胫骨长的一半,第3掌骨至第5掌骨长度依次递减,双耳在额部相连,有横向的嵴,外耳廓近方形,有拱形的耳突;脑颅骨略呈扁平状,颅全长为14.81 ~ 15.74 mm,矢状嵴和人字嵴可见但不明显,齿式为2.1.2.3/3.1.2.3 = 34。综合外部形态、头骨特征和基于Cyt b以及ND1基因的系统发育分析,将其鉴定为北京宽耳蝠(Barbastella beijingensis),为甘肃省、宁夏回族自治区和陕西省翼手目分布新记录种。标本现保存于广东省科学院动物研究所。

    Abstract:

    A total of 25 Barbastella bats (KT13742, KT13743, KT13753, PY13770, and BX13777﹣BX13797) were captured by our research group in June and July 2013 in Pingliang City of Gansu Province, Guyuan City of Ningxia Hui Autonomous Region, and Xianyang City of Shaanxi Province. They are medium-sized bats with forearm length ranging from 42.00 to 45.58 mm. The hind-foot length is less than half of the tibia length, and the length of the 3rd metacarpal bone to the 5th metacarpal bone decreases in descending order (Table 1). These bats have nearly a square outline of ears with transverse ridges (Fig. 1a). Their ears join across the forehead, with a small lobe on the middle outer edge of each pinna (Fig. 1b). The length of skulls ranges from 14.81 to 15.74 mm (Table 1), while both sagittal and lambdoidal crests are weak (Fig. 1d). The dental formula is 2.1.2.3/3.1.2.3 = 34 (Fig. 1c). With 1 000 bootstrap replicates, phylogenetic trees were reconstructed based on cytochrome b (Cyt b) and NADH dehydrogenase subunit 1 (ND1) gene sequences. The specimens in this study clustered with B. beijingensis, rather than B. darjelingensis in both cladograms of Cyt b (Fig. 2) and ND1 (Fig. 3) genes. By comparing external morphology, skull characteristics, and phylogenetic data with B. beijingensis and B. darjelingensis, these bats are identified as B. beijingensis, which are new records of Chiroptera for Gansu Province, Ningxia Hui Autonomous Region, and Shaanxi Province. The above specimens are preserved in the Institute of Zoology, Guangdong Academy of Sciences.
