The holotypes of Plesioblattogryllus magnificus and Duoduo qianae are examined and new synonymies are proposed: Plesioblattogryllus Huang, Nel & Petrulevičius, 2008 = Duoduo Cui, 2012, syn. nov.; Plesioblattogryllus magnificus Huang, Nel & Petrulevičius, 2008 = Duoduo qianae Cui, 2012, syn. nov. The holotype of Plesioblattogryllus minor Ren & Aristov, 2011 is reinvestigated and re-documented, and a new well-preserved single wing of this rare species, also uncovered from the Jurassic Daohugou locality, is described. Besides the holotype, it is the first specimen exhibiting well-exposed wing venation characters for the species. Particular characters, such as the desclerotised MP, are better observed and complemented by Reflectance Transforming Imaging documentation. The new specimen might be a hind wing with a reduced plicatum, a trait yet unknown in grylloblattids. Based on these new data it occurs that, in contrast to P. magnificus and most Blattogryllopterida, the species possesses a long RP+MA fusion, with a long basal free part of MA and a very short basal free section of RP. Together with other characters, it justifies the erection of new genus, Aristoviblattogryllus gen. nov., to accommodate the species Aristoviblattogryllus minor (Ren & Aristov, 2011), comb. nov. %G English %L mnhn-04090638 %U https://mnhn.hal.science/mnhn-04090638 %~ MNHN %~ CNRS %~ CR2P %~ SORBONNE-UNIVERSITE %~ SORBONNE-UNIV %~ SU-SCIENCES %~ ALLIANCE-SU
