The Sichuan bank vole or Sichuan red-backed vole ( Eothenomys chinensis ) is a rodent species from the subfamily of voles (Arvicolinae). It comes in central China and is only documented by the Emei Shan in Sichuan .

features

The Sichuan bank vole is a comparatively large species of the genus and reaches a head-trunk length of 10.1 to 12.5 centimeters with a tail of 6.3 to 7.6 centimeters in length . The rear foot length is 19 to 24 millimeters and the ear length 12 to 15 millimeters. The back fur is gray-brown and the peritoneum slate-gray with a characteristic pink-sand-colored wash in the middle area of the abdomen. The tail is more than half as long as the head-torso length and thus in proportion longer than in all other species of the genus. It is dark brown on the top and a little lighter on the underside. The tops of the feet are gray-brown.

distribution

The Sichuan bank vole occurs in central China and is only documented by the Emei Shan and Leshan in Sichuan . The species has been proven on both sides of Dadu He .

Way of life

There is hardly any information about the way of life of the species. It lives in wooded areas and meadows at altitudes of 1500 to 3000 meters. The breeding season extends from early summer to late autumn.

The animals are allopatric to the Southwest Chinese bank vole ( Eothenomys custos ), the Yulungshan bank vole ( Eothenomys proditor ) and the Ward bank vole ( Eothenomys wardi ).

Systematics

The Sichuan 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 1891 using individuals from the region around Leshan on the Emei Shan . The species was chosen as a type of its own genus Anteliomys , but is today again an independent species in the Eothenomys chinensis species complex within the genus Eothenomys .

No subspecies are distinguished within the species.

Status, threat and protection

The Sichuan bank vole is classified as Least Concern by the International Union for Conservation of Nature and Natural Resources (IUCN). Although the range covers less than 20,000 km², this classification is justified with the assumed large populations of the species, the ability to adapt to different habitats and the lack of risks that endanger the population.
