title: Cytogenetic studies of Hynobiidae (Urodela) XVI. Comparative C-banded karyotype analysis of Pseudohynobius flavomaculatus (Fei et Ye), Ranodon shihi (Liu) and Batrachuperus pinchonii (David).
abstract: Initial analysis of Pseudohynobius flavomaculatus chromosomes determined the chromosome number of this species to be 2n = 52. A re-examination of Ranodon shihi chromosomes detected 2n = 66 chromosomes, in contrast with a previous finding of 2n = 64. The C-banding patterns of these two species and that of Batrachuperus pinchonii were compared with each other. Regions of homoeology in the C-banding pattern among these three species represented 33.51-48.30% of the total length of their chromosomes. We also detected two types of chromosome rearrangement in hynobiid species based on the results of the present and previous cytogenetic studies.
