Family MURIDAE Illiger, 1811

Although the European species Apodemus sylvaticus has been mentioned as a species occurring in Korea (Lee & Lim 1974), we here consider that records of the species originated from erroneous identifications (Pavlinov & Khlyap 2012). Although Musser and Carleton (2005) listed A. chejuensis as a subspecies on Jeju Island, we treat the taxon at the specific level based on reproductive isolation with A. agrarius on the Korean Peninsula. Therefore, we list eight species of Muridae (and four genera) for Korea.
