New beetles (Insecta, Coleoptera) from the Nedubrovo locality, terminal Permian or basal Triassic of European Russia

Recently collected fossil remains of Asiocoleidae, Taldycupedidae, Schizocoleidae, and Permosynidae, Cupedidoidea incertae familiae are described from the Nedubrovo locality (terminal Permian or basal Triassic of European Russia). The beetles are represented by isolated elytra and their position in the natural system often cannot be established; they are therefore described in the formal system. Schizicoleids are dominant in the oryctocoenosis. Permosynids, which codomitated with schizocoleids at the end of the Permian (Upper Vyatkian), are no longer codominant in this locality. Cupedidoidea are unexpectedly abundant; their elytra are very similar to those described from the Severodvinian locality Isady.
