Collection locations for (a) Apodemus argenteus and (b) A. speciosus. The Japanese islands were divided into five geographical regions, Hokkaido, Eastern Honshu, Western Honshu, Shikoku, and Kyushu. The solid line indicates the border of the karyotype forms of eastern (2n = 48) and western (2n = 46) Honshu in A. speciosus. Circles indicate collection locations. Numbers with circles correspond to the locality number in Table 1
