Female.

Body size: 2.0-2.5 mm. Color: body light to medium brown; scape yellow without lateral brown stripe, flagellum brown with apical white annulus, apical 3-5 flagellomeres brown; wing veins light brown, stigma yellow; legs yellow. Head: vertex weakly granulate or smooth; frons weakly granulate or smooth; face weakly granulate or partially smooth; temple in dorsal view broad but sloping 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; 22-23 flagellomeres. Mesosoma: mesoscutal lobes weakly granulate, often smooth near prescutellar furrow; notauli smooth or weakly scrobiculate anteriorly, meeting at scutellum in weak costate or often smooth area; scutellum smooth; prescutellar furrow with 3-5 cross carinae; mesopleuron granulate; precoxal sulcus smooth, shorter than mesopleuron; venter smooth; propodeum with basal median areas distinctly margined, granulate, basal median carina absent or rarely very short, areola indistinctly margined, areolar area areolate-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 shorter than vein 1M. Metasoma: first tergum longitudinally costate, length equal to or sometimes slightly greater than apical width; second tergum longitudinally costate; anterior transverse groove present, straight; posterior transverse groove present; third tergum costate basally, smooth apically; terga 4-7 smooth rarely weakly granulate at extreme base; ovipositor half as long as metasoma.
