New beetles (Insecta, Coleoptera) from Vyazniki locality, terminal Permian of European Russia

Recently collected fossil beetles from the families Asiocoleidae, Rhombocoleidae, Schizocoleidae, and Permosynidae are described from the locality Vyazniki, terminal for the Permian of European Russia. The findings are represented by isolated elytra, the position of which in the natural system it is often impossible to establish; they are, therefore, described in a formal system. The oryctocenosis is dominated by schizocoleids and permosynids, which start to play an important role at the very end of the Permian. They probably include members of Adephaga and Polyphaga, the principal groups of Mesozoic-Cenozoic beetles. Each of the other two families is represented by a single specimen.
