Insects from a new Ufimian Locality of Troitsa in the Perm Region, Russia

摘要

The cockroach ?Phyloblatta vrsanskyi sp. nov. (Insecta: Blattida) from a new Lower Permian locality of Troitza (Ufimian Stage, Solikamskian Horizon) is described. Representatives of the orders Homoptera and Trichoptera from this locality are identified to genus. It is shown that, among Ufimian insect assemblages of the Perm Region, Troitsa is more similar to the later Vorkuta locality than to Tyul'kino, which is of the same age as Troitsa.
