Karyotype (number, shape, chiasma frequency), C-band and AgNORs pattern of Gampsocleis glabra, G. ussuriensis, and G. sedacovi (represented by two subspecies, G. s. sedacovi and G. s. obscura) are reported. Differences in the chromosome number, mean chiasma frequency, and position of C-band (paracentromeric, interstitial, and distal) between species are discussed.
