P₁ elements of this species from the borehole Kowala have already been illustrated as Bispathodus ultimus by Nehring-Lefeld (1990). Probably also specimens identified with the Tournaisian Pseudopolygnathus vogesi by Dreesen et al. (1976) from the Famennian of Belgium are conspecific. There is a possibility that this is the beginning of the P. primus lineage, as suggested by findings of populations morphologically close and transitional in time. However, an independent origin of the Carboniferous Pseudopolygnathus from a less elaborate latest Famennian Pseudopolygnathus seems more likely because of the substantial gap in continuity in the late Famennian and much wider population variability of P. primus (covering also morphologies typical for the late Famennian) than is observed in P. ostrovkensis Dzik, 2006
