Flagellum strongly lanceolate, with 41 flagellomeres; 1 st flagellomere (without anellus) 1.9× longer than wide, 2 nd flagellomere 2.0× longer than wide, combined length c.0.51× eye length; flagellomeres beyond middle slightly attenuated and widened, widest flagellomeres c.2.0× wider than long. Temple slightly and roundly narrowed behind eye. Distance of lateral ocellus from eye c.1.3× its diameter. Face and frons punctate and finely granulate; clypeus punctate and shining.

Hind femur with scattered punctures in ventral 1/3, 3.2× longer than wide. Fore and mid tarsomeres moderately enlarged; 3 rd mid tarsomere 1.5× longer than wide. Areolet pentagonal, frontal distance between veins 2rs-m and 3rs-m 3× their width; vein 2m-cu in its middle. Vein 1cu-a postfurcal by 2× its width.

Lateral field of postpetiolus punctate, 0.7‒0.8 as wide as median field, the latter with strong aciculation and some apical punctures.

Stripes on flagellomeres 7‒12, palps, facial and frontal orbits, large triangular vertical spot, small spot on gena, collare and upper margin of pronotum, subtegular ridge, apical half of scutellum, postscutellum, upper division of metapleuron, spots on 2 nd lateral area of propodeum, dorsolateral spots on 1 st to 4 th tergites, spots on all coxae, apical margins of all trochanters, fore and mid femora apically, fore and mid tibiae frontally, subbasal rings of all tibiae and external spots on 2 nd to 4 th hind tarsomeres yellow. Wings slightly infuscate, pterostigma dark brown.

♂: Body length 17‒20 mm. Flagellum with 39‒44 flagellomeres, 1 st flagellomere 1.9‒2.0× longer than wide.

OED 1.0‒1.1× and OOD 1.1× ocellar diameter. Frons coarsely rugose-punctate. Face and clypeus densely punctate, clypeus with some ± distinct longitudinal rugae. Gena with rather dense punctures, c.0.8× as wide as eye. MI 0.2‒0.4.

Notaulus distinctly impressed in frontal 1/4 of mesoscutum. Mesoscutum densely punctate and granulate, but shining. Mesopleuron and metapleuron with dense punctures, juxtacoxal carina present. Scutellum moderately elevated, slightly longer than wide, without or with lateral carina in basal 1/3, with dense punctures. Propodeum rounded. Area superomedia slightly elevated, heart- or sickle-shaped, 1.5‒2.0× wider than long, sometimes conflu- ent with area basalis; anterior transversal carina in caudal third. Area externa punctate and granulate. Fore metatarsus with strong apical tooth. Hind femur 4.0× longer than wide. Areolet pentagonal, frontal distance between veins 2rs-m and 3rs-m 2‒3× their width; vein 2m-cu in its middle. Vein 1cu-a postfurcal by 1‒3× its width.

Lateral field of postpetiolus 0.6‒0.7× as wide as median field, punctate, median field aciculate. Gastrocoelus strongly impressed. Thyridium transverse, 1.0‒1.25× as wide as the interval, the interval narrower than the median field of postpetiolus. 2 nd tergite 1.05‒1.1× longer than wide. 2 nd to 4 th tergites densely punctate, aciculate medially; 5 th tergite with superficial punctures.
