Diaphanopterodea

Reconstruction and photograph of hind wing of Diaphanoptera munieri, from Bethoux & Nel (2003).


Belongs within: Pterygota.

The Diaphanopterodea are a group of plant-sucking insects known from the Middle Carboniferous to the Early Permian (Sinitshenkova 2002), noteworthy for having evolved the ability to fold the wings back along the body apparently independently of the Neoptera.

Characters (from Sinitshenkova 2002): Robust or slender insects of medium to large size (20-80 mm wingspread). Head small with convex lateral eyes, and short to medium length sucking beak directed below. Prothoracic paranota lateral, small. Wings similar, usually almost identical in form and venation of both pairs, lacking archedictyon, moderately or well costalised (with C, SC, and R thick and running relatively close to each other, though costal space sometimes rather wide), with alternating convex (C, R, MA, CuA, A) and concave (RS, MP, CuP), with costal margin straight to moderately convex, MA simple, tightened sub-basally by cross-vein to or fused for a distance with RS, M5 usually retained, cross-vein-like or forming false CuA base. Legs with tarsi three-segmented, otherwise not evidently specialised. Abdomen segments lacking paranota. Ovipositor cutting, with sheath shorter than stylets, bearing long stylus. Cerci very long, very rarely found in males.
