Head: vertex smooth; frons smooth, rarely weakly striate near antennal bases; face smooth; temple in dorsal view broad but not distinctly bulging behind eye, width equal to 1/2 eye width; malar space greater than 1/4 eye height; ocell-ocular distance greater than 2.5 times diameter of lateral ocellus; 21-28 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli scrobiculate, meeting posteriorly in triangular costate area; scutellum weakly granulate or smooth; prescutellar furrow with 3 cross carinae, often with median carina strong and lateral carinae weaker; mesopleuron smooth; precoxal sulcus weakly scrobiculate or smooth; venter smooth; propodeum with basal median areas margined, granulate, basal median carina present and short, areola not distinctly margined, areolar area rugose, lateral areas entirely rugose. Wings: fore wing vein r shorter than vein 3RSa, vein 1cu-a interstitial with vein 1M; hind wing vein SC+R present, vein M+CU as long as 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 at extreme apex; terga 4-7 costate or granulate at base, smooth apically; ovipositor half as long as metasoma.

Comments.

The yellow or light brown metasoma, the yellow stigma and the strongly granulate basal median areas of the propodeum are distinctive for this species.

Etymology.

The specific name is from the Latin luteus, meaning yellow, and the Greek gaster, meaning stomach, in reference to the yellow metasoma.
