Female.

Body size: 5.0 mm. Color: head yellow; scape and flagellum dark brown; mesosoma with propleuron and median mesoscutal lobe yellow, remainder dark brown, propodeum laterally and mesopleuron dorsally slightly lighter; wing veins including stigma dark brown; legs with coxae, trochanters, femora and tibiae yellow, tarsi brown; metasomal tergum 1 dark brown, tergum 2 dark brown medially, yellow laterally, terga 3-5 dark brown medially at base, light brown apically and yellow laterally, terga 6-7 yellow. Head: vertex smooth; frons weakly transversely striate; face smooth; temple in dorsal view narrow, less than 1/2 eye width; malar space slightly greater than 1/4 eye height; ocell-ocular distance about 1.5 times diameter of lateral ocellus; 34 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli scrobiculate, meeting posteriorly in triangular rugose area; scutellum weakly granulate; prescutellar furrow with 3 cross carinae; mesopleuron smooth; precoxal sulcus scrobiculate, shorter than mesopleuron; venter smooth; propodeum with basal median areas margined, granulate, basal median carina present, areola not distinctly margined, areolar area rugose, lateral areas rugose apically, smooth basally. 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, with several distinct cross carinae medially at base, length greater than apical width; second tergum longitudinally costate; anterior transverse groove present, sinuate; posterior transverse groove present; third tergum granulate basally, smooth apically; terga 4-7 smooth, terga 4 and 5 weakly granulate at base; ovipositor longer than metasoma.

Paratypes.

Known only from the holotype.

Comments.

The yellow mesoscutum, long ovipositor, sinuate anterior transverse groove of metasomal tergum 2 and the brown flagellum are distinctive for this species.

Etymology.

The specific name is from the Latin luteus, meaning yellow, in reference to the yellow median mesoscutal lobe.
