Relationship of the families Blattogryllidae, Megakhosaridae, Plesioblattogryllidae and Grylloblattidae is discussed. The diagnoses of Blattogryllidae and Megakhosaridae are clarified.

(type species: Megakhosarina minuscula Aristov, 2008 from the Middle Permian Soyana locality in Russia) is described. Genera Protoblattogryllus Storozhenko, 1992, Mesoblattogryllus Storozhenko, 1992, Megablattogryllus Storozhenko, 1992 and Madygenocephalus Aristov, 2011 are transferred from Blattogryllidae to Megakhosaridae. New combinations are proposed: Mesoblattogryllus conjunctus Storozhenko, 1992 = Costatoviblatta conjuncta (Storozhenko, 1992), comb. n. , Mesoblattogryllus longipennis Storozhenko, 1992 = Costatoviblatta longipennis (Storozhenko, 1992), comb. n.
