They tend to be more ratlike in appearance than typical hamsters, hence the common name ratlike hamster. Many of the species are considered dwarf hamsters. However, members of the genera Allocricetulus, Tscherskia, and Cansumys are often called ratlike hamsters, and so are considered to be members of the genus Cricetulus by many authorities.
Species
editThree species are universally accepted in this genus:
- Cricetulus barabensis — Chinese striped hamster
- Cricetulus longicaudatus — long-tailed dwarf hamster
- Cricetulus sokolovi — Sokolov's dwarf hamster
Two species were moved to the genus Urocricetus in 2018, but have historically been included in this genus:[2]
- Urocricetus alticola — Tibetan dwarf hamster
- Urocricetus kamensis — Kam dwarf hamster
Other species are sometimes recognized, but further research is likely needed to consider them valid:[2]
- Cricetulus griseus — usually considered a synonym of Cricetulus barabensis
- Cricetulus lama — considered a synonym of Urocricetus kamensis by the American Society of Mammalogists, but considered valid by the IUCN
- Cricetulus tibetanus — considered a synonym of Urocricetus kamensis by the American Society of Mammalogists, but considered valid by the IUCN
Additionally, the grey dwarf hamster Nothocricetulus migratorius was included in this genus until 2018.[2]
