Musser and Carleton (2005) supported six forms or species groups. The Rattus norvegicus and R. tanezumi species groups inhabit Korea . Because of recent taxonomic debates ( Heaney & Molur 2016 ), whether R. rattus and R. tanezumi coexist or only R. tanezumi inhabits Korea remains uncertain. Although there is a little possibility of coexisting R. rattus and R. tanezumi in Korea , we suggest populations of R. tanezumi instead of R. rattus live in Korea . Therefore, we delitsted R. rattus and assigned two species accounts for the Genus Rattus in Korea .
