Urocricetus is a genus of hamsters found on the Tibetan Plateau in southern Asia. These species have relatively long tails for a hamster, with brownish upperparts and a pure white underside.

Taxonomy

[edit]

The genus Urocricetus was originally described by the Russian zoologist Konstantin Satunin as a subgenus of Cricetus. Urocricetus would be sometimes recognized as a subgenus of Cricetulus until 2018, when a phylogenetic study revealed this genus to be valid. This genus is a sister taxa to the desert hamster genus Phodopus.[2]

As of 2024, two closely-related species are recognized in this genus:[2]

The species Cricetulus lama and Cricetulus tibetanus are recognized as valid by the IUCN[3][4] but considered a synonym of Urocricetus kamensis by the American Society of Mammalogists[5]. Both of these possibly-valid species live on the Tibetan Plateau,[3][4] while the other valid Cricetulus species occur further north and northeast of the Tibetan Plateau.[6][7][8] More research is needed for this genus at the species level.[2]
