Insecta Plesioblattogryllidae Polyneoptera ‘Grylloblattida’ Blattogryllopterida revision sp. nov. syn. nov.


Here we describe a new species Plesioblattogryllus aristovi sp. nov. from the Middle-Late Jurassic Daohugou Bed and we restore the family Plesioblattogryllidae stat. rest. to its family status (previously junior synonymy of the family Blattogryllidae). This systematic change is supported by the crucial presence vs. absence of tarsal arolia. We also synonymize the monotypic genus Duoduo Cui, 2012 syn. nov. under Plesioblattogryllus Huang et al., 2008 and transfer it to the Plesioblattogryllidae, we transfer its type species Duoduo qianae to the genus Plesioblattogryllus. Finally, we discuss the interspecific variations in the forewing venation of the genus Plesioblattogryllus.
