Description. ♂. Body length 9.5 mm.
Head. Flagellum with 37 flagellomeres, bristle-shaped; 1 st flagellomere 2.4 × longer than wide. Tyloids on flagellomeres 10–17, long-oval, maximally 0.8 × as long as their flagellomeres. Temple long, almost parallel behind eye, slightly narrowed apically (fig. 8B). OED 1.1 × and OOD 1.2 × ocellar diameter. Temple coarsely punctate. Frons rugose-punctate dorsally, with median longitudinal ridge ventrally. Face and clypeus densely punctate. Clypeus slightly convex; apical margin blunt and almost straight (fig. 8A). Mandible with two teeth, ventral tooth slightly smaller than dorsal one, not turned inwards. Malar space 0.7 × as long as width of mandibular base. Genal carina reaching hypostomal carina away from mandibular base.
Mesosoma. Collar of pronotum with small longitudinal median ridge. Notaulus impressed in frontal 1/6 of mesoscutum. Mesoscutum densely punctate, partly rugose-punctate. Mesopleuron densely punctate, partly rugose ventrally; speculum smooth.Metapleuron with finer dense punctures; juxtacoxal carina present.Scutellum moderately and roundly elevated, slightly wider than long, with lateral carina in basal 0.3–0.4. Propodeum completely carinated, with small apophysis (fig. 8C). Area basalis with median tubercle. Area superomedia hexagonal, slightly wider than long; costula reaching its middle. Hind femur densely punctate, 3.9 × longer than wide. Claws simple. Areolet pentagonal, frontal distance between veins 2rs-m and 3rs-m 2.0 × their width. Vein 1cu-a postfurcal by 2.0 × its width.
Metasoma. Postpetiole moderately widened, coarsely rugose-punctate, with blunt latero-median carina basally; median field elevated and distinctly separated (fig. 8D). Gastrocoelus impressed, with longitudinal ridges.Thyridium small, 0.3 × as wide as the interval between thyridia. 2 nd tergite 1.2 × longer than wide. 2 nd to 4 th tergites coarsely rugose-punctate; following tergites with superficial punctures.
Colour. Black. Flagellum black, basal flagellomeres ± reddish-brown. Ivory are palps, basal spot of mandible, clypeus, face except small brownish median spot, wide frontal orbit, scape and pedicel ventrally, collar and upper margin of pronotum, tegula, subtegular ridge, scutellum, apical spot of 6 th tergite, large median spot of 7 th tergite, and fore and mid trochanters. Coxae black, sometimes fore and mid coxae with apical yellowish spots; legs otherwise reddish-yellow; hind tibia slightly and diffusely infuscate apically, hind tarsus black. Wings almost hyaline; pterostigma black.
Distribution. Only known from Sulawesi.
