Female.

Body size: 3.0 mm.

Head: vertex smooth; frons smooth; face smooth; temple in dorsal view narrow, sloping behind eye, width less than 1/2 eye width; malar space greater than 1/4 eye height; ocell-ocular distance slightly greater than 2.5 times diameter of lateral ocellus; 19 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli scrobiculate, meeting posteriorly in triangular costate area; scutellum granulate; prescutellar furrow with 3 cross carinae; mesopleuron granulate; precoxal sulcus scrobiculate, as long as mesopleuron; venter granulate; propodeum with basal median areas margined, granulate, basal median carina present but short, areola not margined, areolar area rugose, lateral areas entirely rugose, apical lateral corners of propodeum distinctly produced into tubercles. Wings: fore wing vein r slightly shorter than vein 3RSa, vein 1cu-a interstitial with vein 1M; hind wing vein SC+R absent, vein M+CU slightly shorter than vein 1M. Metasoma: first tergum longitudinally costate; second tergum weakly costate at base, remainder smooth; anterior transverse groove absent; posterior transverse groove absent; third tergum entirely smooth; terga 4-7 smooth; ovipositor as long as metasomal terga 1 and 2 combined.

Paratypes.

Known only from the holotype.

Comments.

The distinct tubercles at the apical lateral corners of the propodeum and the precoxal sulcus which is as long as the mesopleuron are distinctive for this species.

Etymology.

The specific name is in reference to the distinct tubercles on the propodeum.
