The rear foot length is 16.5 to 20 millimeters and the ear length is 12 to 14 millimeters. The species corresponds in its appearance to the Sichuan bank vole ( Eothenomys chinensis ) and the Ward bank vole ( Eothenomys wardi ), but is somewhat smaller and has a shorter tail. The back fur is dark brown and the peritoneum grayish brown. The tail is dark brown on top and slightly whitish on the underside. The tops of the feet are dark brown with light hair.

distribution

The southwestern bank vole is found in southern China in northwestern Yunnan and central Sichuan .

Way of life

Little information is available about the way of life of the species. It lives in wooded areas at altitudes of 2500 to 4800 meters, where it is mainly found in the area of ​​river banks. It lives less often in open stony meadows, bushes and bamboo stands. The breeding season extends from early summer to late autumn.

Systematics

The Southwest Chinese bank vole is classified as a separate species within the genus Eothenomys , which consists of eight species. The first scientific description comes from the British zoologist Oldfield Thomas , who described the species in 1912 using individuals from the region around A-tun-tsi (Dequen Xian) in Yunnan. The species was placed in the genus Anteliomys , but is today assigned to the Eothenomys chinensis species complex within the genus Eothenomys .

Within the species, five subspecies are distinguished with the nominate form :

  • Eothenomys custos cangshanensis Wang and Li 2000: in Yunnan on Mount Cang in Dali .
  • Eothenomys custos custos (Thomas, 1912): in the northwest of Yunnan.
  • Eothenomys custos hintoni Osgood, 1932: in the west of Sichuan.
  • Eothenomys custos ninglangensis Wang and Li, 2000: in the north of Yunnan and in the south of Sichuan.
  • Eothenomys custos rubellus (Allen, 1924): in northern Yunnan.

Status, threat and protection

The Southwest Chinese bank vole is classified as Least Concern by the International Union for Conservation of Nature and Natural Resources (IUCN). This classification is justified with the relatively large distribution area, which also includes several protected areas, the assumed large stocks of the species and its regular occurrence. There are no known risks to the existence of the species.
