Female.

Body size: 2.5-3.5 mm. Color: head with vertex and frons brown, eye orbits and face lighter brown to yellow; scape yellow, basal 2 flagellomeres yellow, next 8-10 flagellomeres bicolored brown with yellow at apex and base, remainder of flagellomeres brown except apical 3-5 white; mesosoma and metasoma dark brown; legs bicolored yellow with apical 3/4 of middle and hind femora brown; wing veins and stigma brown, wing membrane dusky along vein r. Head: vertex transversely costate; frons transversely costate; face striate at least laterally, often smooth medially; temple in dorsal view narrow, usually less than eye width, occasionally equal; malar space greater than 1/4 eye height; ocell-ocular distance about 2.5 times diameter of lateral ocellus; 15-22 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli scrobiculate, meeting at prescutellar furrow in triangular costate-rugose area; scutellum smooth; prescutellar furrow with one median distinct cross carina, occasionally weak cross carinae on each side; mesopleuron smooth; precoxal sulcus weakly scrobiculate, extending posteriorly to margin of mesopleuron by distinct carinae; venter smooth; propodeum with basal median areas smooth, distinctly margined, basal median carina absent, areola distinctly margined, areolar area rugose, lateral areas entirely rugose. Wings: fore wing vein r shorter than vein 3RSa, vein 1cu-a beyond vein 1M; hind wing vein SC+R present, vein M+CU nearly equal to vein 1M. Metasoma: first tergum longitudinally costate, length greater than apical width; second tergum longitudinally costate; anterior transverse groove present, straight; posterior transverse groove absent; third tergum costate basally, smooth apically; terga 4-7 smooth; ovipositor usually longer than metasoma, occasionally only slightly longer and appearing equal in length.
