The study examines the variability of the cytochrome b (c ytb ) gene fragment in the grey red-backed vole ( Craseomys rufocanus ) from the southwest of Primorsky Krai. A total of 16 new haplotypes distributed across two distinct phylogroups were identified. The findings suggest classifying the F-haplotype as a separate phylogenetic group and subdividing phylogroup D into two distinct subgroups. Preliminary data on the geographical distribution of mtDNA lineages in the south of the region are also presented. A notable trend was observed in the decreasing frequency of C-2-haplotypes from north to south, and of D-haplotypes from west to east. Additionally, the presence of exclusively D-haplotypes in the southwest of Primorsky Krai suggests a potential barrier effect of the Suifun-Khanka Plain on the distribution of the grey red-backed vole in this area.
