There are 25 Platysoma species known from the Palaearctic out of about 65 species described in the genus globally (Mazur, 2011; Lackner et al ., 2015; Ôhara & Ahn, 2018). Five species are reported from Primorsky Krai , but only two of them belong to the nominative subgenus (Kryzhanovskij, 1989). The third species from this subgenus found recently in the southern Primorsky Krai appeared to be the species recently described from South Korea . These beetles are found under bark of conifers, in bark beetle galleries.
