Antennae polymerous, rarely with 15 flagellomeres, usually more ( 14–17 in Cretocleistogastrinae). Forewing with pterostigma comparatively narrow (widely triangular or semicircular in Cretocleistogastrinae), M+Cu fork much closer to pterostigma than to wing base (nearly equidistant in Nevaniinae); 2–3r-m and 2m-cu always present (lost in Cretocleistogastrinae, only 2r-m lost in Anomopterellinae); 3r cell moderately wide (very wide and nearly triangular because of long and almost straight apical section of RS in Anomopterellinae); 2A absent (present in Nevaniinae). Hindwing with C absent (present in Nevaniinae), R strong, reaching apex of Rs and forming a distinct vein; cells rm and cua always closed (R lost beyond hamuli and cua cell lost in Cretocleistogastrinae). Ovipositor long, with sheaths more than half length of metasoma (shorter in Anomopterellinae). Remarks .
