Revision of the family Epideigmatidae (Insecta: Grylloblattida)

The family Epideigmatidae is revised. New members of this family from the Lower Permian of Russia: Vilvaptera permyakovae, gen. et sp. nov. (Vilva locality, Artinskian Stage, Perm Region) and Tshekardeigma rasnitsyni, gen. et sp. nov. (Chekarda locality, Kungurian Stage, Perm Region) are described. Paraphenopterum unicolor Storozhenko, 1992 (Soyana locality, Kazanian Stage, Arkhangelsk Region) is redescribed. The family Stenoneuritidae is regarded as a synonym of Epideigmatidae; the genera Fayoliella Meunier, 1908 (Upper Carboniferous of France), Fabreciella Carpenter, 1934 (Upper Carboniferous of the USA), and Turbopterum Kukalová, 1964 (Lower Permian of the Czech Republic) are transferred to Epideigmatidae. Fabreciella allegheniensis Carpenter, 1934 is synonimized under F. pennsylvanica Carpenter, 1934.
