江西武夷山发现亚洲宽耳蝠

本研究组于2018年1月在江西省武夷山自然保护区,使用蝙蝠竖琴网捕获到1只雄性蝙蝠,采用传统形态分类并结合系统发育学分析方法,对该蝙蝠进行物种鉴定。其主要特征为:体型中等偏小,前臂长38.29mm;外耳廓呈方形,双耳在额部相连,耳屏呈现三角形,无耳突;背毛和腹毛黑棕色且毛尖偏白色;头骨从吻端均匀上升,颅顶点隆起不明显,整体较为扁平;颧弓纤细,矢状嵴与人字嵴隐约可见,齿式为2.1.2.3/3.1.2.3=34。根据其外部形态、头骨特征及基于Cytb和ND1基因序列的系统发育树结果,将该蝙蝠鉴定为亚洲宽耳蝠(Barbastella leucomelas),为中国江西省翼手目分布新记录种。

Barbastella leucomelas Found at Wuyi Mountain of Jiangxi Province

In January 2018, when investigating chiropteran diversity Wuyi Mountain in Jiangxi province, a male vespertilionid bat was captured by using harp trap. We identified this bat through morphological examination and phylogenetic inference. It is medium-sized bat with a forearm of 38.29 mm (Table 1) and the black-brown fur with white tip. Its tragus is triangular. Ears are nearly square with transverse ridges and connect in the forehead without a prominent projecting lobe (Fig. 1a). Besides, skull rises evenly from the rostral to the end, the vertex of skull is not prominent (Fig. 1c). The zygomatic arch is slender, while both sagittal and lambdoidal crests are weak. Its dental formula is 2.1.2.3/3.1.2.3 = 34 (Fig. 1b, c). According to its external, skull characteristics and phylogenetic evidences using partial Cyt b and ND1 gene, it is identified as Barbastella leucomelas which representing a new record species in Jiangxi Province, China.
