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 ) .
