Maximum length of temple 0.72 × transverse eye diameter; minimum length of temple 0.6 × transverse eye diameter. Face 1.08 × height of eye; in dorsolateral profile convex, medially bulging ( Fig. 6 ). Clypeus separated by impression; at apex projecting anteriorly; apical margin of clypeus obtuse. Clypeal foveae large and elongate. Malar space 0.6X basal mandible width. Lower mandible tooth longer than upper. Occipital carina medially complete.

Mesosoma matt. Notaulus absent. Mesopleuron matt, deeply and finely punctate ( Fig. 4 ). Tarsi with apical article not enlarged. Claws not pectinate. Fore wing with areolet petiolate. Radius intercepting pterostigma before its middle. Second recurrent vein with single bula. Hind wing with nervellus intercepted below middle. Nervulus postfurcal. Propodeum with carinae partly complete. only area petiolaris raised, rounded ( Fig. 5 ).

Metasoma shining, setose, coarsely punctate. First metasomal tergite 0.68X as long as apically wide; with shallow median longitudinal impression; bordered by lateral longitudinal carinae; dorsal longitudinal carinae absent. Second metasomal tergite transverse. Ovipositor short, as long as metasomal height.
