摘要

摘要: 该研究中，我们在安徽大别山地区采集到了鼩鼹类标本四号，根据已发表的文献和资料进行对比后，发现这些标本类似于分布在中国西南山区的亚洲鼩鼹。通过对上述标本和鼩鼹属物种的形态学比较、系统发育分析和物种界定分析，发现该鼩鼹标本应为一新种。研究中还对该新种进行了描述，将其命名为Uropsilus dabieshanensis sp. nov. （大别山鼩鼹）。大别山鼩鼹的发现不仅使鼩鼹属在中国的分布范围扩展到了中国东部的大别山区，同时也提升了该属的物种多样性水平。

Abstract: During a terrestrial vertebrate survey of the Dabie Mountains in Anhui Province, eastern China, we collected four Asian shrew mole specimens (hereafter, shrew moles). Based on published literature and comparison with previously collected materials, the four specimens were similar to shrew moles from the mountains of Southwest China; however, no species in this group has been previously recorded from the Dabie Mountains. The genetic and morphological characteristics of the specimens were analyzed, based upon which a new species of shrew mole is described, named Uropsilus dabieshanensis sp. nov.
