The Brachystigmata are a clade of dragonflies that mostly have fairly short pterostigmata in the wings (Bechly & Ueda 2002).

Synapomorphies (from Bechly & Ueda 2002): Wings with relatively short pterostigmata that cover only 1–3 complete cells (reversed in Libellulinae); “gaff” (= basal CuA before its branching) in hind wing strongly prolonged and very straight in the groundplan (sigmoidal in Eurypalpidomorpha); area between MP and CuA basally widened with more than one row of cells (reversed in some subclades); terminal branch of CuAa secondarily branched on CuA (inapplicable whe CuAa is secondarily unbranched); RP3/4 and MA strictly parallel up to the hind margin; area between RP2 and IR2 distally distinctly widened, with more than one cell row in the distal half (sometimes reversed).
