Cricetulus
Cricetulus is a genus of rodent in the family Cricetidae (voles and hamsters); it has seven member species that inhabit arid or semi-arid regions in Eurasia.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.Three species are universally accepted in this genus: Two species were moved to the genus Urocricetus in 2018, but have historically been included in this genus:[2] Other species are sometimes recognized, but further research is likely needed to consider them valid:[2] Additionally, the grey dwarf hamster Nothocricetulus migratorius was included in this genus until 2018.
