Abstract
New material of Orthoptera from the Upper Triassic and Lower Jurassic of England is considered. Some problems with generic composition and diagnostics of the subfamily Protogryllinae (Protogryllidae) from the suborder Ensifera and of the subfamily Locustopsinae (Locustopsidae) from the suborder Caelifera are discussed. One new genus and two new species are described: Daniilacheta aristovi gen. et sp. nov. (Protogryllinae) and Plesioschwinzia sharovi sp. nov. (Locustopsinae). Some additional species, previously attributed to Locustopsis Handlirsch, are tentatively included in Plesioschwinzia Zessin. New specimens, possibly belonging to Locustopsis spectabilis Zeuner, are briefly described and illustrated.
