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

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]
