Abstract


To reexamine taxonomic status of endemic Mogera wogura coreana from Korea, we first obtained partial 12S rRNA sequences (893 bp) and complete cytochrome b gene sequences (1140 bp) of this subspecies, and these sequences and partial cytochrome b sequences (402 bp) were compared to the corresponding haplotypes of M. wogura from East Asia, obtained from GenBank. The one of three 12S rRNA haplotypes in M. w. coreana was identical to one 12S rRNA haplotype of M. w. robusta from East Asia: 10 complete and 13 partial cytochrome b haplotypes of M. w. coreana formed a single clade with one complete and four partial cytochrome b haplotypes of M. w. robusta, respectively. We considered that M. w. coreana from Korea is an endemic subspecies with only morphological differences, although it is necessary to reexamine the subspecies status of M. w. coreana. Additionally, in the 12S rRNA and complete cytochrome b sequences, M. wogura from Japan was distinct from the two continental subspecies of M. w. coreana and M. w. robusta with average distances of 1.76 and 5.65%, respectively; insular M. wogura, with within-group distances of 2.09 and 4.38%, respectively, was also genetically more divergent than the mainland M. wogura, with within-group distances of 0.08 and 0.57%, respectively. Thus, we considered that insular M. wogura of Japan dispersed into neighboring East Asian continent, which is opposite to the traditional hypothesis on the origin of Japanese M. wogura.
