Body size: 2.5 mm. Color: head with vertex and frons brown, face and temple honey yellow; scape yellow without lateral brown stripe, flagellum yellow basally to brown apically; mesosoma brown; metasoma brown to dark brown; wing veins including stigma brown; legs yellow. Head: vertex transversely costate; frons transversely costate; face rugose; temple in dorsal view narrow, width less than 1/2 eye width; malar space greater than 1/4 eye height; ocell-ocular distance about twice diameter of lateral ocellus; 16 flagellomeres. Mesosoma: mesoscutal lobes granulate; notauli scrobiculate, meeting at scutellum in triangular rugose area; scutellum granulate; prescutellar furrow with 5 cross carinae; mesopleuron granulate; precoxal sulcus weakly scrobiculate, shorter than meso pleuron; venter granulate; propodeum with basal median areas margined, granulate, basal median carina absent, areola weakly margined, areolar area areolate-rugose, lateral areas entirely rugose, apical-lateral corners of propodeum produced into blunt tubercle. Wings: fore wing vein r as long as vein 3RSa, vein 1cu-a beyond vein 1M; hind wing vein SC+R absent, vein M+CU shorter than vein 1M. Metasoma: first tergum longitudinally costate, apical width equal to length; second tergum longitudinally costate; anterior transverse groove present, straight; posterior transverse groove absent; third tergum costate basally, smooth apically; terga 4-7 smooth; ovipositor equal to length of metasomal tergum 1.

Paratypes.

Known only from the holotype.

Comments.

The tubercles on apical-lateral corners of the propodeum, the rugose face and the absence of hind wing vein SC+R are distinctive for this species.

Etymology.

Named for G. Enderlein who described numerous South American braconids in the early 1900s.
