New data and systematic considerations on the Blattogryllopterida (Insecta: Grylloblattida) from the Jurassic Daohugou locality in China

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 <em>P. magnificus</em> 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 a new genus, <em>Aristoviblattogryllus</em> <strong>gen. nov.</strong>, to accommodate the species</span><span> </span><em><span>Aristoviblattogryllus</span></em><em><span> </span></em><em><span>minor</span></em><span> </span><span>(</span><span>Ren & Aristov, 2011</span><span>), <strong>comb. nov</strong></span><strong><span>.</span></strong></p>
