抄録: We performed allozyme analysis for three Korean (Hynobius leechii, H. quelpaertensis, and H. yangi) and three Japanese (H. nebulosus, H. tsuensis, and H. dunni) salamanders to clarify their interspecific relationships using H. naevius as an outgroup. The genetic distances (Nei’s D) within ingroup species ranged from 0.11 to 0.78 with a mean of 0.33. In the NJ and CONTML trees, monophyly of the ingroup was not supported and Korean H. quelpaertensis and H. leechii diverged first from the remaining species, which together formed a weakly supported clade. Korean H. yangi, long identified as H. leechii, was closer to Japanese H. nebulosus (D=0.108) and H. tsuensis (D=0.138) than to Korean H. leechii (D=0.197) and H. quelpaertensis (D=0.305). Hynobius tsuensis and H. nebulosuswere very close (D=0.108) despite their different breeding habits. A geohistorical hypothesis is proposed to explain the divergence of the six species.
