Karyotype of Hynobius leechii from Cheju Island, Korea

The karyotype of Hynobius leechii from Cheju Island, Korea is described. Previous studies indicated that the Cheju population is phenotypically dissimilar to the populations from mainland Korea. However, the karyological results obtained from squash preparations of intestinal epithelia indicate that the Giemsa-stained karyotype in this population is quite similar to those of mainland populations.
