The  Rattus norvegicusand  R. tanezumispecies groups inhabit Korea. Because of recent taxonomic debates ( Heaney & Molur 2016), whether  R. rattusand  R. tanezumicoexist or only  R. tanezumiinhabits Korearemains uncertain. Although there is a little possibility of coexisting  R. rattusand  R. tanezumiin Korea, we suggest populations of  R. tanezumiinstead of  R. rattuslive in Korea. Therefore, we delitsted  R. rattusand assigned two species accounts for the Genus  Rattusin Korea.
