The Palaeodictyoptera are a group of usually large (sometimes extremely large) plant-sucking insects known from the latest Early Carboniferous to the Late Permian (Sinitshenkova 2002).

Characters (from Sinitshenkova 2002, as Dictyoneurida): Body stout, large to very large (up to 50 cm wingspread or more). Integument rather thick, finely granulated. Head with sucking beak moderately to very long, directed obliquely forward. Prothoracic paranota either circular or, usually, forming winglets. Wings spread permanently (not folding over abdomen at rest). Both wing pairs similar except minor venational differences and wider base of hind wing, with either rich archedictyon or numerous cross-veins (exceptionally cross-veins less common, forming transverse rows), sometimes with evident nygmata, often brightly patterned. Longitudinal veins straight or gently curved, rarely with CuP and A more strongly curved; occasionally merging for a distance and then more sharply bent. C often running submarginally, leaving narrow precostal space.
