Popis: Paoliida is an insect group of highly controversial composition and equally controversial affinities. Based on comprehensive reinvestigations we propose a new delimitation of the insect order Paoliida sensu nov. associating the families Paoliidae and Blattinopsidae on the basis of the following main wing venation characters: veins CuA convex and CuP concave separating from a rather long basal stem Cu; a short, more or less distinct, but generally convex arculus brace (crossvein) between M and CuA (more distinct in forewing than in hind wing), and a broad area containing veinlets, between CuP and CuA, with a general course of CuA making a double curve (autapomorphy); CuP straight or sigmoidal. The Paoliida is considered as a neopteran clade and potential sister group of the Dictyoptera on the basis of the presence of well-defined anterior branches of CuA, with the same convexity as the median vein and more concave than the posterior branches of the same vein (synapomorphy). The polarities of the other char...
