姬鼠属小鼠广泛分布于欧亚大陆。该属的几个物种是重要的人畜共患疾病和寄生虫的宿主。这些小鼠的进化历史和扩散途径仍不清楚，之前的研究也很少探讨这些物种在中国的分布。我们研究了姬鼠的分化时间和历史地理演化，并通过整合分子和形态学数据来研究中国物种的分类。该属的树冠年龄可追溯到中新世晚期，大约为 9.84 Mya。西亚和中亚被推断为该属最有可能的祖先地区。此外，我们还发现中国现存九种姬鼠：乌拉氏姬鼠、黑姬鼠、切氏姬鼠、拉特罗姬鼠、半岛姬鼠、龙姬姬鼠、冬青姬鼠、塞莫特姬鼠和黑姬鼠。 11月，最后一次从贵州梵净山和重庆金佛山高地（海拔>1984米）出发。这个新物种与 A. draco、A. semotus 和 A. ilex 分歧约 4.53 Mya。黑曲霉的发现凸显了高山作为中国东南部温带物种的避难所和“生态孤岛”的重要性。
Mice of the genus Apodemus are widely distributed across Eurasia. Several species of this genus are hosts of important zoonotic diseases and parasites. The evolutionary history and dispersal routes of these mice remain unclear and the distribution of these species in China was poorly explored in previous studies. We here investigate the divergence times and historical geographical evolution of Apodemus and study the taxonomy of species in China by integrating molecular and morphological data. The crown age of this genus is dated to the Late Miocene, approximately 9.84 Mya. Western and Central Asia were inferred as the most likely ancestral area of this genus. Moreover, we recognize nine living species of Apodemus in China: Apodemus uralensis, A. agrarius, A. chevrieri, A. latronum, A. peninsulae, A. draco, A. ilex, A. semotus and A. nigrus sp. nov., the last from the highlands (elevation > 1984 m) of Fanjing Mountain in Guizhou Province and Jinfo Mountain in Chongqing Province. This new species diverged from A. draco, A. semotus and A. ilex approximately 4.53 Mya. The discovery of A. nigrus highlights the importance of high mountains as refugia and ‘isolated ecological islands’ for temperate species in south-eastern China.
