Malar space about 1.1 times as long as basal mandibular width. Inner margin of eye parallel. Vertex sparsely punctate more than face. Frons smooth. Temple polished and convex, with fine punctures. Antenna filiform with 47 (47–55) flagellomeres.

Thorax with dense and long pubescence. Pronotum broad with transversly fused punctures from middle to ventroposterior corner, apical margin hook-shape, epomia absent. Mesopleuron with epineminal carina to basolateral part, fairly uniformly punctate but median part polished without puncture, postpectral carinae absent, sternaulus absent. Metapleuron moderately convex, with moderately dense puncture. Submetapleural carina complete, anterior half developed ( Fig. 4 ). Mesoscutum convex, densely irregularly punctate, notaulus absent. Scutellum, in profile, strongly convex, densely punctate. Propodeum in dorsal view closely punctate, transversely striated, tending to rugose apically, spiracle of propodeum small and oval-shaped ( Fig. 5 ). Legs slender. Fore tibial spur sinuate. Fore and mid tarsal claws pectinate. Hind tarsal claw simple with accessory tooth ( Fig. 2 ). Each trochantellus without a sharp apical tooth on the outer side. Fore wing 8.3 mm (8.3–9.5 mm), areolet with moderately long petiole, nervulus intercepted at middle. Hind wing with 8 hamuli, nervellus intercepted slightly below middle.

1st tergite slender, 5.5 (5.5–5.8) times as long as posteriorly broad anteriorly without lateral longitudinal carina. 2nd tergite coriaceous, 2.3 times as long as posteriorly broad. Ovipositor sheath slender, with dense, short hair, as long as abdomen.

Frontal collar and hind corner of pronotum yellow. Tegula and subtegular ridge yellow. Small spot on lower hind corner of mesopleuron yellow. Metapleuron with an inverted U-shaped yellow mark. Mesoscutum with a pair of basolateral yellow spots. Scutellum yellow. Fore and mid legs whitish yellow except for blackish brown 5th tarsomere and tarsal claw. Hind coxa yellow except for black dorsal posterior part. Trochanter and trochantellus yellowish brown. Femur yellowish brown except for black base and apex. Tibia yellow except for black base and blackish brown apical and tibial spur. Tarsus yellow. Tarsal claw black. Apex of fore wing with weak spot. Abdomen black. Basal halves of 1st and 2nd tergites yellow. Base and apex of 3rd tergite yellow, apex of 4th–7th yellow. Membranous area of sternites brown. Ovipositor reddish brown. Ovipositor sheath blackish brown.
