Mesoscutum with coarse puncture and granulation, matte. Mesopleurum punctured, anteriorly and below the speculum with some longitudinal striae. Metapleurum with scattered puncture, especially on ventral margin. Coxal carina distinct. Scutellum slighly convex, wider than long, with strong lateral carina and scattered puncture. Area basalis smooth with median tubercle, Area superomedia with complete carination, dome-shaped, almost 2x as long as wide, smooth, costula in its middle. Area petiolaris with lateral carina, rugose. Coxa III punctured, without scopa. Femur III with superficial puncture, about 4.0x as long as high.

Postpetiole moderately widened. Lateral field of postpetiole punctured, median field smooth, dorsal carina not developed. Gastrocoelus deeply impressed, with some longitudinal striae. Thyridium slightly oblique, about as wide as the thyridial interval. Second tergite 0.95x as long as wide. Tergites 2-4 with coarse rugulo-puncture, matte, tergite 2 with irregular median striation. Ovipositor sheath seen from dorsal about as long as the seventh tergite.

Cream-yellow are stripe on flagellomeres 8-16, mandible except teeth, palps, labrum, clypeus, face, gena, orbit completely, scapus beneath, anterior and upper margins of pronotum, subtegular ridge, lower half of mesopleurum and complete mesosternum, two longitudinal stripes on mesoscutum, prescutellar ridge, sides of scutellum, postscutellum, carinal triangle, metapleurum centrally, area dentipara, apical bands on tergites 1-4 (on tergites 3-4 with narrow interruption medially), very small lateral spot on tergite 5 (on the left side only), small apical mark on tergite 6 and tergite 7 mainly, coxae and trochanters I-II, and dorsal spot on coxa III. Legs including coxa III reddish. Femur III red, infuscate in the apical 0.2, tibia III yellowish medially and infuscate basally and apically. Tarsus III cream-yellow. Pterostigma yellowish, margins darkened.
