The 4 Mvotis species had the karyotypes of 2n : 44 with FN : 50 (M. m. gracilis and M. f. tsuensisl or 52 (M. d. ussuriensis and M. mncrodactylus). Furthermore the karyotype of R obrumus (2n : 26, FN : 441 seemed advanced compared with that of U coreensis (2n : 44, FN : 501 which is similar to the original karyotype of Mvotis species (2n : 44, FN : 50).
