Since then, few were observed or collected, and the presence of A. sylvaticus in Korea appears questionable ( Han 1994 , 2004c ). We regard these records as erroneous identifications of A. peninsulae . The identifications of A. sylvaticus were based on the presence of a long tail, long hind foot and long ears (especially the tail longer than the head-body length), but measurements overlapped those of A. peninsulae , previously a subspecies of A. sylvaticus and later a subspecies of A. speciosus . Also, the location of Korea is substantially beyond the eastern limit of the distribution for A . sylvaticus . Thus, we removed Apodemus (or Sylvaemus ) sylvaticus ( Linnaeus, 1758 ) from the list of Korean mammals. Although some references used chejuensis as a subspecies of A. agrarius , we considered A. chejuensis a distinct species because a reproductive barrier was confirmed between the two species ( Jo et al . 2017b ). Thus, we list three species of Apodemus in Korea .
