Description of Unknown Female. Body length 7.8–8.0 mm. Black; antenna beneath and tarsi yellowish or ivory-white; mandible apically, antenna above, tibiae, tegula, wing veins, gastral segments I–IV or just tergum IV basally, and pygidial area apically reddish brown or fulvous. Setae on clypeus silvery, dense; pubescence on frons, vertex, thorax and legs sparse, silvery, on propodeum dense, silvery.

Clypeus with dense, fine punctures; free margin with four prominences medially, round or sinuate; area near free margin with transverse, round tubercle medially, tubercle shiny, impunctate; basal half of clypeal disk conspicuously elevated. Mandible bidentate apically. Interantennal tubercle round, inconspicuous. Antenna claviform, segments III–XII toward gradually thicker and shorter toward apex; segment III about 3 ×, segment IV about 2 ×, segment XI about 1 × as long as wide apically, respectively. Upper frons with fine, contiguous punctures; ocellar area and vertex medially with fine punctures that are one diameter apart; ocellar area slightly elevated. HW: HLD: HLF = 85: 31: 68; POD: OOD: OCD = 12: 13: 15.

Anterior portion of mesoscutum with fine, dense punctures; middle and posterior portions of mesoscutum with sparse, medium to large punctures that are 1.5–2 × diameters apart. Scutellum finely, sparsely punctate. Metanotum with dense, slender, irregular rugae. Mesopleuron shiny, sparsely, finely punctate, lower portion with slender, sparse, long, longitudinally oblique ridges posteriorly; upper mesopleuron with contiguous, fine punctures, and slender, longitudinal rugae. Propodeal enclosure delimited by triangular, conspicuous carina, with shallow depression, and slender, longitudinal rugae; posterior surface of propodeum with dense, slender, longitudinal rugae laterally, remainder with slender, irregular, reticulate rugae; lateral surface of propodeum with dense, slender, longitudinally oblique ridges. Both first and second recurrent veins of forewing ending in second submarginal cell. Legs normal, hind tibia with one or two rows of slender yellowish spines on outer surface, spines slightly longer than adjacent pubescence.

Petiole shiny, somewhat elongate; dorsal surface of petiole moderately convex; basal width of petiole in dorsal view equal to its apical width; lateral and ventral surfaces of petiole flat, without carina or keel. PL: PW: LTI: WTI: HFL: HTL = 40: 8: 43: 42: 48: 55. Hind trochanter not reaching end of petiole, femur far exceeding end of petiole. Gastral segments shiny, impunctate; pygidial area elongate, triangular, with dense, fine punctures and setae, apex obtuse.
