Wings: fore wing vein r shorter than vein 3RSa, vein 1cu-a beyond vein 1M; hind wing vein SC+R absent, vein M+CU shorter than vein 1M. Metasoma: first tergum longitudinally costate, apical width equal to length; second tergum longitudinally costate; anterior transverse groove present, straight; posterior transverse groove usually weakly present, occasionally absent; third tergum costate at extreme base, remainder smooth; terga 4-7 smooth; ovipositor as long as metasomal tergum 1.
