Abstract:
The grylloblattid fauna that existed from the Late Permian to the first half of the Triassic is reviewed. Two new species of the family Geinitziidae, Stegopterum anteanatalis sp. nov. (Lek-Vorkuta Forma- tion, Pechora Basin) and Shurabia annosa sp. nov. (Mal'tseva Formation, Kuznetsk Basin), are described. Ste- gopterum hirtum Shar., Megakhosara fasciipennis Mart., and Syndesmorpha composita Mart. are redescribed. The family Stegopteridae becomes a subfamily of the family Geinitziidae. Alicula asiatica is transferred to the genus Metidelia of the family Ideliidae.
