Based on COI DNA barcoding data, the distribution of 2 species of Buldowskia, namely B. shadini (Moskvicheva, 1973) and B. suifunica (Lindholm, 1925) is clarified in southern Primorsky Krai in the Russian Far East. Buldowskia suifunica is confirmed from freshwater basins in the Khasansky District (the southernmost part of the Primorye). The presence of B. shadini in the coastal drainages, not part of the basin of Lake Khanka, and in the Razdolnaya river basin is noted for the first time. Both species are shown to occur in the Razdolnaya river basin, although they do not occur together at the same localities. Distinct distribution and low intraspecific divergence of B. shadini suggest that it was unintentionally introduced into the rivers of southern Primorsky Krai. B. suifunica is native to the Razdolnaya River basin, its distribution is apparently associated with the regression of Sea of Japan in the Pleistocene. The outer shell microsculpture of B. suifunica glochidia consists of a multilayered loosely looped network in the centre of the valves, which differs from the other studied anodontines with loop-like microsculpture of the exterior of glochidial valves.
