( Figs. 2 , 5 , 8 , 10 , 13)

Male. Head: Lower face uniformly brown. Torulus slightly dorsal to midline of eye. No carina present between toruli; area of the frons dorsal to toruli slightly convex. Eye 0.75 times head height. Epistomal declivity of clypeus divergent. Gena nitid, always uniformly brown. Malar space punctulate, setose, 0.4 times eye height. Middle third of clypeus expanded ventrally as even, semicircular process. Vertex defined by slight, irregular sculpture. Scape and pedicel brown but usually lighter than flagellum. Flagellomeres 1–7 yellow to brown; flagellomeres 8–11 dark brown. Mandible light brown-yellow medially, reddish on dorsal and ventral margins, with 4 reddish teeth on anterior face of mandible (5 teeth total).

Mesosoma: Propleuron rugulose. Mesopleuron rugose in dorso-anterior corner, regularly areolate along posterior edge (areolas nearly square); median concave area rugose, with rugae almost reaching dorso-anterior corner. Areas dorsal and ventral to the medial depression nitid. Mesoscutum and scutellum nitid, evenly brown and setose. Notaulus inconspicuously sinuous (often almost linear), posteriorly with dilation inconspicuous, convergent and joined at scutellar groove. Tegula brown to light brown, nearly spherical. Metapleuron nitid along anterior edge, irregularly areolate medially. Mesosternum nitid laterally, strongly rugulose (almost areolate in some specimens) medially. Metasternum strongly rugose. Lateral face of propodeum nitid anteriorly. Posterior face of propodeum, ventral to the petiole articulation, alveolate. Fore leg and mid leg mostly nitid except faintly imbricate or prelate ventrally, gradually fading from brown to light brown towards apices sculpture. Hind leg fading from brown to light brown apically.

Wings: Fore wing with 6 cells enclosed by tubular veins. 1st subdiscal cell open, 2A and 2cu-a absent. 3CU vein spectral. Hind wing with three adjacent hamuli.

Metasoma: Gaster elliptical, much less than half the size of the mesosoma in lateral view. Petiole 4 times longer than medial width, as wide as high, arched dorsally; rugose laterally; slightly flared posteriorly (expanding in width and height).

Female description: As for male except: eye strongly elliptical, smaller (0.5 times head height), flatter. Flagellomeres brown (apical flagellomere light brown to yellow), widened progressively towards apex. Frons nitid and shiny. Notaulus sinuous, not widening posteriorly. Gaster half as large as mesosoma in lateral view. Ovipositor sheaths bare except for tuft of setae/sensilla at apex. Ovipositor short (about as long as petiole), straight, and usually concealed within metasoma.
