Abstract
The taxon Blattogryllopterida tax.n., whose distinctive character is ‘in forewing, M + CuA splitting into MA and MP + CuA’ (as opposed to ‘into M and CuA’), is erected to make possible a taxonomic assignment of isolated grylloblattidan wings which cannot be conclusively assigned either to the Blattogryllidae or the Plesioblattogryllidae. Material of two blattogryllopteridan species collected from the Daohugou locality (Middle Jurassic; Northeast China) is described. The limited available data on the species Plesioblattogryllus minor Ren & Aristov, 2011 are complemented by descriptions of four wellpreserved specimens, some exhibiting variation in wing venation. Duoduo qianae gen.n. et sp.n. is erected on the basis of an isolated wing. Characters useful for the identification of members of the families Blattogryllidae and Plesioblattogryllidae as well as characters possibly linking these taxa with the extant Grylloblattidae are discussed.
