Description. ♀. Body length 10.8 mm.
Head. Flagellum with 34 flagellomeres, very long and slender; 1 st flagellomere 5.6 × longer than wide; all flagellomeres much longer than wide. Temple rather long, moderately and roundly narrowed behind eye (fig. 15B). OED 1.4 × and OOD 0.7 × ocellar diameter. Temple finely punctate. Frons with microsculpture and sparse fine punctures. Face densely but superficially punctate, ± shining. Clypeus large, superficially punctate, almost flat; apical margin blunt, slightly bilobed (fig. 15A). Mandible sickle-shaped, ventral tooth absent. Malar space 0.8 × as long as width of mandibular base. Gena densely punctate. Genal carina reaching mandibular base.
Mesosoma. Covered with short setae. Notaulus impressed in frontal 0.3 of mesoscutum. Mesoscutum densely but superficially punctate, ± shining. Mesopleuron finely punctate, ventrally part striate in its frontal half; speculum large, smooth and shining. Metapleuron with smoothened surface; juxtacoxal carina present. Scutellum strongly pyramidal, about as long as wide, coarsely rugose, lateral carina in its basal 0.6. Propodeum completely carinated, with strong apophysis (fig. 15C); spiracle slit-shaped. Area superomedia small, hexagonal, about as wide as long; anterior transverse carina reaching at 4/10 of its length. Hind coxa with fine dense punctures, without scopa. Hind femur 4.6 × longer than wide. Claws simple. Areolet almost quadrangular, frontal distance between veins 2rs-m and 3rs-m 1.0 × their width. Vein 1cu-a interstitial.
