The first genetic study of the holotype of the Gansu short-tailed shrew, Thomas, 1912, is presented. The mitochondrial analysis demonstrated that the type specimen of is close to several recently collected specimens from southern Gansu, northern Sichuan and Shaanxi, which are highly distinct from the two species of Asiatic short-tailed shrews of southern Sichuan, Yunnan, and Vietnam, and . Our analysis of four nuclear genes supported the placement of as sister to / , with the level of divergence between these two clades corresponding to that among genera of Soricinae. A new generic name, , is proposed for the Gansu short-tailed shrew. Karyotypes of (2 = 49, NF = 50) and (2 = 49, NF = 62) from southern Gansu are described. The tribal affinities of Blarinellini and Blarinini are discussed.
本文首次对1912年托马斯所描述的甘肃长尾鼩的模式标本进行了遗传学研究。线粒体分析表明,该模式标本与最近从甘肃南部、四川北部和陕西采集的几个标本相近,这些标本与四川南部、云南和越南的两种亚洲长尾鼩明显不同。我们对四个核基因的分析支持将甘肃长尾鼩置于与/的姐妹群位置,这两个分支之间的分歧水平与鼩鼱亚科各属之间的分歧水平相当。为甘肃长尾鼩提出了一个新的属名。描述了来自甘肃南部的(2n = 49,NF = 50)和(2n = 49,NF = 62)的核型。讨论了长尾鼩族和北美鼩鼱族的亲缘关系。
