Summary
| Description | Figure 3: Phylogeny of Acercaria (drawn by RG). List of synapomorphic characters. Clade Acercaria: characters ‘1’ (common stem R + M + CuA), ‘2’ (neutral crossvein cua-cup between concave CuP and convex CuA), ‘3’ (elongate lacinia). Clade [Psocodea + (Permopsocida + (Thripida + Hemiptera))]: characters ‘4’ (clypeus divided by a furrow into ante- and postclypeus, but a character variable in Pterygota), ‘5’ (maxillary lacinia not in direct contact with stipes), ‘6’ (cerci absent), ‘7’ (reduction of number of tarsomeres to four or less). Clade [Permopsocida + (Thripida + Hemiptera)]: characters ‘8’ (paraclypeal lobes present), ‘9’ (labrum elongate), ‘10’ (mentum elongate and sclerotized), ‘11’ (gena divided into two lobes). Clade Permopsocida: characters ‘12’ (ocell-ocular distance < inter-ocellular distance), ‘13’ (tarsi four-segmented), ‘14’ (pterostigma in hind wing limited by costal wing margin and a deep posterior curve of vein RA), and ‘15’ (abdominal segment 1 narrow and reduced). | |||
