Summary
A primitive representative of the Caudata endemic to Japan,Hynobius abei Sato (Caudata: Hynobiidae) has 2n=56 chromosomes, with 9 large, 4 medium and 15 small-sized homologous pairs. The morphology of the large-sized chromosomes is similar to that of the knownHynobius species, but the presence of a pair of acrocentrics in the medium-sized group and 5 pairs of biarmed chromosomes in the small-sized group characterized the karyotype ofH. abei.
