List of calomyscids

Calomyscidae is a family of small rodents found in Syria, Azerbaijan, Iran, Turkmenistan, Afghanistan, and Pakistan that contains a single genus, Calomyscus. A member of this family is called a mouse-like hamster, brush-tailed mouse, or calomyscid. Most members of this family are commonly referred to as belonging to the species Calomyscus bailwardi, the first mouse-like hamster to be described. There are no population estimates for any of the known mouse-like hamsters, and most are considered as least-concern species, with two noted as being data deficient by the International Union for Conservation of Nature (IUCN).

There are 8 extant calomyscid species contained within a single genus, Calomyscus. Two extinct Calomyscidae species are known: C. delicatus Aguilar et al. 1984 and C. minor de Bruijn et al. 1970. New extant species that are not recognized by the IUCN have been discovered in the 2020s, including Behzad's brush-tailed mouse (C. behzadi) and the Kerman brush-tailed mouse (C. kermanensis).
