Diagnosis.

Doryctopambolus sarochensis sp. n. distinguishes from the remaining species of the genus by having the vertex striate-rugose (striate in Doryctopambolus pilcomayensis comb. n. and smooth in the remaining two species), two pairs of propodeal apico-lateral projections, the basal ones small and blunt and the second pair long and distinctly truncate, and third metasomal tergite costate baso-laterally (entirely smooth in the other species).

Description.

Female. Body length 3.0 mm; fore wing 2.0 mm; ovipositor 1.7 mm. Colour: head brown, malar space honey yellow, antenna honey yellow, turning brown at apex, mandible honey yellow, palpi yellow; mesosoma and metasoma dark brown to black; wings slightly infuscate; veins and stigma brown; fore leg honey yellow; middle leg honey yellow, with femur light brown; hind coxa and femur brown, trochanter, trochantellus, tibia and tarsi honey yellow; ovipositor and sheaths honey yellow, apex strongly sclerotised and dark. Head: 23 antennomeres; eyes setose; face striate medially, striate-rugose laterally, with median area slightly swollen; clypeus costate-rugose; malar space 0.6 times eye height; frons and vertex striate-rugose; temple in dorsal view 0.8 times eye width. Mesosoma: two times longer its maximum height; pronotum rugose laterally; pronotal groove wide and scrobiculate; propleuron costate-rugose; mesoscutal lobes mostly smooth and shinning, rugose along notauli and at lateral edges; notauli narrow and scrobiculate, meeting before scutellum in a longitudinally costate-rugose area; scutellum smooth, with some setae; scutellar sulcus with three parallel carinae; height of scutellar sulcus 0.8 times height of scutellar disc; subalar sulcus wide, deep and scrobiculate, joining mesopleural sulcus in an inverted “V” shape; mesopleuron porcate dorsally, porcate-rugose laterally, smooth ventrally; venter of mesopleuron smooth; propodeum with two pairs of apico-lateral projections, the most basal one small and blunt, the apical one long and distinctly truncate, longer than first flagellomere. Legs: hind coxa strongly costate-rugose dorsally, poorly sculptured ventrally. Wings: fore wing length 3.8 times its maximum width, r:3RS:3RSb = 3:6:22; 2RS:3RSa:r-m = 8:6:5; m-cu arising antefurcal with vein 2RS; 1cu-a interstitial with 1M. Metasoma: length of first metasomal tergite 1.5 times its apical width, apical width about 2.0 times basal width, costate rugose with two dorsal carinae converging at apex; second metasomal tergite strongly costate; third metasomal tergite mostly smooth, costate baso-laterally, remaining metasomal tergites smooth and polished; basal sternal plate (acrosternite) about 0.33 times length of tergum; ovipositor as long as metasoma.

Variation.Females. Body length 2.7-3.0 mm; antenna with 22-23 antennomeres. Males. Unknown.

Genetic distances.

Interspecific variation of the barcoding locus among the examined species of Doryctompambolus , Doryctopambolus clebschi (two specimens), Doryctopambolus dominicanus (one specimen), Doryctopambolus sarochensis (two specimens) and the two undescribed species from Venezuela (one specimen each), was congruent with the interspecific variation observed in other braconid genera, ranging from 4.2 to 14%. The lowest interspecific genetic distance occurred between specimens of the two Dominican species, Doryctopambolus clebschi and Doryctopambolus dominicanus .
