Female.

Body size: 2.5-3.5 mm. Color: body entirely honey yellow; scape yellow without lateral longitudinal brown stripe, flagellum yellow basally to brown apically; legs yellow; wing veins brown, stigma yellow. Head: vertex transversely striate; frons transversely striate; face rugose; temple in dorsal view broad, not sloping behind eye, width about 1/2 eye width; malar space less than 1/4 eye height; ocell-ocular distance about 1.5 times diameter of lateral ocellus; 19-25 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli scrobiculate, meeting at scutellum in triangular rugose area; scutellum granulate; prescutellar furrow with one distinct cross carina; mesopleuron usually smooth, often weakly granulate; precoxal sulcus smooth, shorter than mesopleuron; venter granulate; propodeum with basal median areas margined, granulate, basal median carina absent, areola not distinctly margined, areolar area rugose, lateral areas entirely rugose. Wings: fore wing vein r usually slightly shorter than vein 3RSa, occasionally equal, vein 1cu-a beyond vein 1M, vein RS+Ma distinctly curved or sinuate; hind wing vein SC+R present, vein M+CU equal in length to vein 1M. Metasoma: first tergum longitudinally costate, apical width equal to length; second tergum longitudinally costate; anterior transverse groove present, straight; posterior transverse groove present; third tergum costate basally, smooth apically; tergum 4 costate basally, smooth apically; terga 5-7 smooth; ovipositor as long as terga 1+2 combined.

Biology.

Reared from Bauhinia pauletia and Bauhinia glabra invested with the bruchids Gibbobruchus guanacaste , Gibbobruchus cristicollis , Caryedes x-liturus and Caryedes cavatus .

Comments.

This species is distinguished by the distinctly curved or sinuate fore wing vein RS+Ma, the yellow body, prescutellar furrow with one cross carina and short ocell-ocular distance

Etymology.

The specific name is from the Latin sinuatus, meaning curved or bent, in reference to the distinctly curved fore wing vein RS+Ma.
