Flagellum lanceolate, with 44 flagellomeres, first flagellomere 3.4x, the second one 2.9x as long as wide, together about 0.7x as long as compound eye, widest flagellomeres 1.6x as wide as long. Temple short, strongly narrowed behind eye, seen from lateral 0.6x as wide as eye, with superficial puncture. Distance of lateral ocellus to compound eye about 1.0x its diameter. Frons smooth below, above with fine transverse median striation, sides punctured. Face with scattered puncture, intervals smooth, clypeus almost completely smooth. Malar space 0.5x as long as width of mandibular base. Hypostomal carina not elevated.  
Mesosoma with short whitish hairs. Sides of pronotum with superficial puncture dorsally and some strong striae ventrally. Notaulus impressed at the anterior margin of mesoscutum. 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.

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.
