Propodeum with sharply defined anterior horizontal and posterior vertical faces, its median length 0.7X maximum width. Tarsal comb short, apical spine of tarsomere 1 scarcely touching the apex of tarsomere 2; apical spine of tarsomeres 2 and 3 projecting over the apex of tarsomeres 3 and 4 correspondently, tarsomere 1 with three spines, tarsomere 2 with two, tarsomere 3 with one, tarsomeres 4 and 5 without spines. Longer spur of mid tibia 0.8X tarsomere 1, longer spur of hind tibia 0.64X tarsomere 1. Claws symmetrical with additional inner tooth. Fore wing slightly infuscate, venation as in Fig. 12. Pterostigma small, slightly longer than first abscissa of R. Second abscissa of R 2.17X third abscissa of R.

Frons, supraclypeal area, gena, vertex, propleuron, and coxa with scattered erect long black setae. Mandible with two long curved strong black setae and seven shorter ones. Posterior half of pronotum, mesoscutum, mesoscutellum with sparse black setae. Mesepisternum anterior to coxa with black setae. Metanotum and propodeum lacking setae. Posterior border of S2–S5 with sparse erect black setae, S6 with scattered setae. T5–T6 with sparse black setae. Face with pale pubescence, frons, pronotum, and mesonotum with brownish pubescence, propleuron, mesopleuron, metanotum, coxa with iridescent pale pubescence; metasoma with very weak pubescence.
