Caryomys is a genus from the subfamily of voles (Arvicolinae) with two species that occur in mountains in the central People's Republic of China . You stay in damp forests, such as gallery forest or laurel forest .

The following types are recognized:

  • Gansu bank vole or Eva's red-backed vole ( Caryomys eva ), lives at high altitudes between 2600 and 4000 meters above sea level. The species eats seeds, grass, young leaves and other shoots.
  • Kolan bank vole or Inez red-backed vole ( Caryomys inez ), can be found in lower areas between 500 and 2000 meters above sea level.

Caryomys was originally described by Oldfield Thomas as a subgenus of field mice ( Microtus ). The species was later classified in the Père David voles (genus Eothenomys ). In 1996, a genetic test found that Caryomys has a different karyotype than Eothenomys and bank voles ( Myodes ). That is why newer taxonomic treatises and the World Conservation Union (IUCN) list Caryomys as an independent genus.

The Caryomys species are similar in general physique and in the shape of the fur to the Père David's voles. Both genera have rootless molars that are constantly growing ( hypsodontia ). The crowns of the molars of the Caryomys species, on the other hand, correspond to the molar crowns of the bank voles ( Myodes ).
