To reexamine genetic divergence of Korean Crocidura lasiura from an adjacent far-eastern Russian population, we obtained Cyt b complete nine sequences (1 140 bp) of C. lasiura from four locations in Korea and three locations in far-eastern Russia, and these sequences were compared to the corresponding complete four and partial (402 bp) four sequences of C. lasiura, obtained from GenBank. We found from this Cyt b complete sequence analysis that Korean C. lasiura is not monogenic, and concluded that Cyt b partial sequences of C. lasiura have to be used with caution for population structure investigation. More importantly, we detected from this analysis with Cyt b complete sequences that Korean C. lasiura is distinct from other C. lasiura in far-eastern Russia, with average JC distance of 1.08% and seven fixed site differences, and consider that genetically divergent Korean C. lasiura has not been in contact from other C. lasiura in adjacent far-eastern Russia even during the last glacial maxima. Finally, we found that present sequencing results do not support the current subspecies classification, recognizing C. lasiura as a monotypic species, but do support a previous classification, recognized Korean C. lasiura as C. l. thomasi, although further sequencing analyses with more C. lasiura specimens from northeastern China are needed to confirm the present findings.
