Summary

Karyotypes have been studied in 3 species ofHynobius and in 1 species each of the remaining genera of Hynobiids (Ranodon, Batrachuperus, Salamandrella andOnychodactylus). All species have large diploid numbers, between 56 and 66, and asymmetrical and bimodal karyotypes. DNA contents (2C) were found to vary between 33 and 51 pg. Determination was not possible inOnychodactylus where higher values may be suspected. Some of the karyotypes investigated are similar to those of Cryptobranchids. Phylogenetic implications are discussed.
