D e s c r i p t i o n of: Body length 9.0 mm. Flagellum with 32 flagellomeres, first flagellomere 3.3x as long as wide. Wide-oval tyloids on flagellomeres 9-18. Temple short, strongly narrowed behind eye. Distance of lateral ocellus to compound eye about 1.1x its diameter. Frons smooth, above with superficial puncture. Face and clypeus with puncture, intervals smooth. Malar space about 0.5x as long as width of mandibular base. Genal carina meets the hypostomal one close to mandibular base. Hypostomal carina not elevated.

Mesosoma with short whitish hairs. Notaulus weakly impressed. Mesoscutum with dense puncture and fine granulation, but more or less shining. Mesopleurum with coarser puncture speculum smooth. Metapleurum with scattered puncture. Coxal carina distinct. Scutellum moderately convex, wider than long, with complete lateral carina and scattered puncture. Areae basalis and superomedia confluent and smooth. Area petiolaris with lateral carina, punctured. Femur III about 4.0x as long as high.

Areolet pentagonal, frontal distance of intercubiti 2x its diameter, nervulus postfurcal.

Postpetiole moderately widened. Median field with fine striation. Gastrocoelus large, triangular. Thyridium oblique, 0.3x as wide as the thyridial interval. Second tergite 0.9x

as long as wide. Tergites 2-3 with fine rugulo-puncture, matte, tergite 2 with median striation in the basal half.

Coloration: Black. Cream-yellow are stripe on flagellomeres 6-17, mandible, palps, clypeus except a small dark triangular median spot at apex, face, gena, orbits except a narrow interruption on malar space, scapus beneath, anterior and upper margins of pronotum, subtegular ridge, longitudinal stripe on lower mesopleurum, sides of scutellum, postscutellum, apical half of area dentipara, dorsolateral spots on postpetiolus and tergites 2-3, narrow apical bands on tergites 2-6 and tergite 7 almost completely, parameres, coxae I-II, all trochanters, anterodorsal spot on coxa III. Coxa III otherwise black. Legs yellowish-red.Femur III reddish-brown, diffusely infuscate in the apical half, tibia III infuscate in the apical 0.4, tarsi II-III blackish. Pterostigma dark brownish.

unknown.

R e m a r k: This taxon is characterized by the wide-oval tyloids, large ivory stripe on flagellum and the coloration of the metasoma.
