Cytogenetic studies of Hynobiidae (Urodela). XI. Banding karyotype of Salamandrella keyserlingii Dybowski and a comparison with those of Hynobius species.

C- and R-banding analyses were performed on chromosomes of Salamandrella keyserlingii, in which 20 of 31 chromosome pairs could be identified. Banding patterns were compared between S. keyserlingii and specimens of Hynobius species of the family Hynobiidae. Between S. keyserlingii and six Hynobius species (2n = 56), there were four homoelogous and two partially homoeologous chromosome pairs. Between S. keyserlingii and H. retardatus (2n = 40), there were two homoeologous and two partially homoeologous chromosome pairs.
