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.
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]
Cricetulus is a genus of rodent in the family Cricetidae ; it has seven member species that inhabit arid or semi-arid regions in Eurasia.
Water voles are large voles in the genus Arvicola. They are found in both aquatic and dry habitat through Europe and much of northern Asia. A water vole found in Western North America was historically considered a member of this genus, but has been shown to be more closely related to members of the genus Microtus. Head and body lengths are 12–22 cm, tail lengths are 6.5–12.5 cm, and their weights are 70–250 g. The animals may exhibit indeterminate growth. They are thick-furred and have hairy fringes on their feet that improve their swimming ability.
The Chinese striped hamster, also known as the striped dwarf hamster, is a species of hamster. It is distributed across North Asia from southern Siberia through Mongolia and northeastern China to northern North Korea. An adult Chinese striped hamster weighs 20 to 35 g, and has a body length of 72 to 116 mm with a tail of 15 to 26 mm. It is smaller and has a much shorter tail than the greater long-tailed hamster, Tscherskia triton, which inhabits much of the same range.
The Korean field mouse, also known as the Korean wood mouse, is a species of mouse. It is distributed across Northeastern Asia, including the Russian Far East, northern China, the Korean Peninsula, Sakhalin, and Hokkaidō. It is not found on the Korean island of Jeju. The adult has a body length of 76–125 mm, with a tail of nearly equal length (75–112 mm).
The Mongolian hamster is a species of rodent in the family Cricetidae. It is one of two members of the genus Allocricetulus, and is found in China, Russia, and Mongolia.
The Tibetan dwarf hamster is a species of rodent in the family Cricetidae. It is found not only in Tibet and China, but also in India and Nepal in mountainous regions at altitudes of up to about 5,200 m (17,100 ft). It was moved from the genus Cricetulus to Urocricetus in 2018.
The Kam dwarf hamster is a species of rodent in the family Cricetidae. It is found only in the mountains of western China where it inhabits grassland, shrubby marshes and steppes. Although it has a limited range, the International Union for Conservation of Nature has assessed its conservation status as being of "least concern". It was recently moved from the genus Cricetulus to Urocricetus.
The long-tailed dwarf hamster is a species of rodent in the family Cricetidae. It is found in China, Kazakhstan, Mongolia, and Russia.
The grey dwarf hamster, grey hamster or migratory hamster is a species of rodent in the family Cricetidae. Its range extends from Eastern Europe through the Middle East, Russia and Central Asia to Mongolia and western China. The grey dwarf hamster has grey fur and a head-body length ranging from 85 to 120 mm. The International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
The yellow steppe lemming is a species of rodent in the family Cricetidae. It is found in China, Kazakhstan, and Mongolia. Its natural habitat is temperate desert.

The Lama dwarf hamster is a species of rodent in the family Cricetidae. It is found only in the mountains of western China where it inhabits grassland, shrubby marshes and steppes. Although it has a limited range, the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
The Ikh Nartiin Chuluu Nature Reserve, commonly shortened to Ikh Nart Nature Reserve is a protected area in Dornogovi Province, Mongolia. It occupies part of two counties, Dalanjargalan and Airag. The nature reserve has an area of about 66,000 hectares and was established in 1996. It consists of rocky outcrops surrounded by dry grassland and semi-desert steppe and is one of the places in which the rare argali wild sheep can be found.
