Head and pronotum yellowish-orange; remainder of mesosoma black; metasoma orange; wings blackish with a pale subapical patch; face sparsely punctate and moderately protruding dorsally; clypeus smooth, with median subapical tubercle moderate, ventral margin truncate; frons laterally smooth, medially transversely striate, with two submedian carinae diverging toward lateral ocelli; antenna with 36 flagellomeres; mesopleuron with epicnemial carina reaching level of mesopleural pit; subtegular ridge convex; fore wing with 2m–cu slightly apical to rs–m; tergite 1 stout in female (male unknown); tergites 1–3 smooth, following tergites moderately punctate with basal transverse striations; apical margins of all tergites straight. CT 2.0; ML 0.6; POL 1.3; OOL 1.6; Fl 1 3.6; Fl 15 2.1; FL 33 0.9; T1 1.3; OT 4.4.
A species with unique color pattern, with most of mesosoma black, metasoma orange and wings blackish with a subapical light patch; otherwise characterized by the sparsely punctate face, the truncate ventral margin of the clypeus and the stout tergite 1 of the female.

COLOR. Head and pronotum yellowish-orange with mandible and ocellar area black; remainder of mesosoma blackish testaceous; metasoma orange; fore leg and mid leg from tibia yellowish orange, remainder of legs blackish testaceous; antenna and ovipositor sheath brown; wings strongly infuscate but with large subapical and small mid-dorsal pale yellowish patches on fore wing.
HEAD. Face sparsely punctate, almost smooth laterally, and moderately protruding dorsally; clypeus smooth, with a moderate subapical median tubercle, ventral margin truncate; mandible stout; frons laterally smooth, medially transversely striate; inner margin of toruli expanded backwards into two weak sinuate submedian carinae, carinae then diverging and reaching lateral ocelli; frons also with an additional lateral curved carina from posterior margin of torulus to next to lateral ocellus; vertex and temples almost smooth, inter-ocellar area somewhat rugose; occipital carina mid-dorsally evanescent; hypostomal carina strongly raised above mandibular base; antenna with 36 flagellomeres.
MESOSOMA. Mesosoma finely, sparsely and shallowly punctate, but mesonotum transversely striate and pronotum, speculum area and propodeum medially smooth; epomia very weak; dorsal faint apex of epicnemial carina reaching level of mesopleural pit; apex of subtegular ridge convex, not flanged laterally; submetapleural carina moderate and even all along.
WINGS. Fore wing with 2m–cu slightly apical to rs–m, cu–a slightly apical to Rs+M, Rs moderately bowed forwards; hind wing with distal abscissa of Cu joining Cu&cu–a at its anterior third, remote from junction with M.
METASOMA. Tergite 1 moderately stout; tergites 1–3 smooth, following tergites moderately punctate with weak transverse basal striations; apical margins of all tergites straight.
