The Père David voles or David voles ( Eothenomys ) are a genus of voles (Arvicolinae) with eight species that are found mainly in the People's Republic of China . As a type species was the first to describe Gerrit Smith Miller , the Pere David Rötelmaus selected, after the French priest and naturalist Jean Pierre Armand David is named.

features

The species of the genus are voles with a dark fur, which very often has a brass-like sheen. They are distinguished from other vole genera primarily on the basis of skull and tooth features and are also subdivided into species groups within the genus. Like the two species of the genus Caryomys that are often associated with the Pere David voles, they have rootless molars, which are constantly growing ( Hypsodontie ). The crowns of the molars of the Caryomys species, on the other hand, correspond to the molar crowns of the bank voles ( Myodes ). A characteristic of Myodes and is also that the females only have two pairs of teats , the pairs are missing in the armpit and chest area.

distribution

The species have their distribution center in central and southern China , with some species also spread further south to India and Myanmar .

Systematics

The genus Eothenomys was established by Gerrit Smith Miller in 1896, using the Père David bank vole ( Eothenomys melanogaster ), first described by Alphonse Milne-Edwards in 1871, as a nomenclature type . The genus consists of eight species in total, which are divided into an Eothenomys chinensis and an Eothenomys melanogaster species group:

Eothenomys chinensis species group
  • Sichuan bank vole or Sichuan red-backed vole ( Eothenomys chinensis )
  • Southwest Chinese bank vole or Atunsi red-backed vole ( Eothenomys custos )
  • Black- eared bank vole or black-eared red-backed vole ( Eothenomys olitor )
  • Yulungshan bank vole or Yulungshan red-backed vole ( Eothenomys proditor )
  • Ward's bank vole or Chamutong red-backed vole ( Eothenomys wardi )
Eothenomys melanogaster species group
  • Kachin bank vole or Burmese red-backed vole ( Eothenomys cachinus )
  • Père David's bank vole or Père David's red-backed vole ( Eothenomys melanogaster )
  • Yunnan bank vole or Chinese mountain red-backed vole ( Eothenomys miletus )

In some cases, the genus Caryomys was placed in the genus of the Père David voles. In 1996, a genetic test found that Caryomys has a different karyotype than Eothenomys and the bank voles ( Myodes ). That is why newer taxonomic treatises list Caryomys as an independent genus.
