Wings: fore wing vein r shorter than vein 3RSa, vein 1cu-a beyond vein 1M; hind wing vein SC+R present, vein M+CU shorter than vein 1M. Metasoma: first tergum longitudinally costate, apical width equal to length; second tergum nearly 4 times as wide as long, longitudinally costate; anterior and posterior transverse grooves present and indicated by row of distinct pits; third tergum costate basally, smooth apically; terga 4–7 smooth; ovipositor equal to length of metasomal terga 1 and 2 combined.
