Fore wing venation developed or reduced, either no or many cells enclosed by tubular veins; almost always with stigma present. Fore wing with veins C and R separate; a long narrow costal cell present. Antennae with 10 or more flagellomeres. If wing venation developed; fore wing with vein Cu continuing nearly straight to wing margin; with vein 2cu-a as long as, or longer than, vein 1cu-a; and without veins 2r-m and 2m-cu. If venation reduced, metasoma with tergum 1 about the same length as, or shorter than, other metasomal terga, or much narrower than rest of metasoma; head hypognathous; pronotum in dorsal view usually more or less U-shaped; bases of antennae not facing upwards on a ledge on the frons.
If wings reduced or absent; pronotum in lateral view extending to tegula or thorax greatly modified and tegula absent; back of the head rounded in lateral view; tegula usually absent; bases of antennae located far from mouth; scape less than 3 times as long as wide; metasomal sternites as sclerotized as tergites; antennae with 11-13 flagellomeres; metasoma spindle-shaped in lateral view; ovipositor sheath hook-like, directed ventrally (1).
