The Kachin bank vole or Burmese red-backed vole ( Eothenomys cachinus ) is a rodent species from the subfamily of voles (Arvicolinae). It occurs in southern China and neighboring Myanmar .

features

The Kachin bank vole is a comparatively large species of the genus and reaches a head-trunk length of well over 10 centimeters with a tail that is on average more than 5 centimeters long . It corresponds in size and appearance to the Yunnan bank vole ( Eothenomys miletus ), from which it is geographically separated by the Saluen . The back fur is soft, long and dense, it is tan brown. The peritoneum is light grayish with pale sand-yellow or ocher-colored washings. The tail is comparatively long, especially when compared to other species of the Eothenomys melanogaster species complex. The Kachin bank vole also differs from related species in its smaller and flattened skull and the number of fusible ridges on the M3 molars .

distribution

The Kachin bank vole occurs in southern China and the adjacent northeast of Myanmar . In China, she lives in Yunnan west of the Saluen and in Zayü County in the Tibet Autonomous Region .

Way of life

There is hardly any information about the way of life of the species. The Kachin bank vole lives in dense mountain forest regions at altitudes of 2300 to 3000 meters, where it prefers slopes and river bank areas.

Systematics

The Kachin 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 1921 using individuals from the Kachin State in northern Burma, now Myanmar. Partly the species was assigned to the Père David bank vole ( Eothenomys melanogaster ) or the Yunnan bank vole ( Eothenomys miletus ), today it is considered a separate species in the Eothenomys melanogaster species complex.

No subspecies are distinguished within the species.

Status, threat and protection

The Kachin bank vole is classified as Least Concern by the International Union for Conservation of Nature and Natural Resources (IUCN). This is justified with the relatively large distribution area and the assumed large populations of the species that also occur in protected areas. Potential threats to the species are mainly deforestation in the distribution area.
