Abstract

|
Genetic and morphological variations of Korean Hynobius leechii were surveyed. Starch gel electrophoresis was used to study genetic variation at 23 loci. H. leechii is genetically divided into three groups, each of which is named as Form?A, Form?B, and Form?C. These forms are clearly separated with 4?5 fixed or nearly fixed allelic differences. At a sympatry near Jangseong, Jollanam?do, a significant deviation from random mating between Form?A and Form?B was observed. Therefore, they are considered as two distinct taxa of specific rank. Form?A is widely distributed in the inland of Korea, whereas Form?B is distributed in the islands or near the coastal regions of Western and Southern Korea. Form?B had, in addition, a significant morphological difference from Form?A. On the other hand, Form?C was restricted to an area near Kori atomic power plant, Kyongsangnam?do, and the genetic similarities between this form and Form?A and Form?B were 0.742 and 0.736, respectively. Moreover, Form?C had a unique color pattern, short body and small coccyx. Thus, it seems reasonable to assign this form as another new species.
