Head: vertex smooth; frons smooth; face weakly striate medially, smooth laterally; temple in dorsal view narrow, width less than 1/2 eye width; malar space slightly greater than 1/4 eye height; ocell-ocular distance about 2.5 times diameter of lateral ocellus; 23-24 flagellomeres.

Wings: fore wing vein r slightly 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-granulate, length equal to apical width; second tergum longitudinally costate-granulate; anterior transverse groove present, straight; posterior transverse groove present; third tergum costate basally, smooth apically; terga 4-7 smooth; ovipositor half as long as metasoma.

The sparse long hair along the notauli, the bicolored metasomal tergum 2 and the absence of the basal median carina of the propodeum are distinctive for this species.


Named for the Roman god, Saturn.
