Genus Craseomys Miller, 1900

Craseomys was considered a subgenus of Myodes (Musser & Carleton 2005) . Based on cytochrome b, Lebedev et al. (2007) suggested the usage of a separate genus, Craseomys Miller, 1900 for the group Clethrionomys rufocanus, Clethrionomys rex, Clethrionomys andersoni and the Clethrionomys smithii complex. Both mtDNA and nDNA analyzes by Kohli et al. (2014) supported the taxonomic revision proposed by Lebedev et al. (2007). Craseomys includes two Korean species, C. rufocanus and C. regulus . Although C. regulus was once included in Eothenomys, molecular phylogeny placed Eothenomys as the closest taxon to Craseomys (Kohli et al. 2014) .
