Head. Antenna with at least 20 flagellomeres (apical part missing); first flagellomere ca. 4.3× longer than wide. Face ( Fig. 8E ) granulose. Clypeus ( Fig. 8E ) convex, granulose, apical margin arched. Malar space granulose, ca. 0.5× basal width of mandible. Upper tooth of mandible slightly longer than lower tooth, without lamella. Frons ( Fig. 8E ) granulose and without median carina. Vertex ( Fig. 8F ) granulose. Interocellar region ( Fig. 8F ) granulose. Interocellar distance 1.1× ocello-ocular distance and 1.0× distance between median and lateral ocelli; distance between lateral ocelli and eyes ca. 1.1 × as long as diameter of ocellus. Temple mat, ca. 0.35× as long as eyes in lateral view. Occipital carina evenly arched, reaching hypostomal carina above mandible base.

Mesosoma. Pronotum granulose dorsally and transversely striate laterally. Mesoscutum ( Fig. 8G ) granulose, notauli weakly present anteriorly. Scutellum and metanotum granulose. Mesopleuron ( Fig. 8B ) granulose, weakly transversely striate below tegula, speculum smooth and shiny. Metapleuron ( Fig. 8B ) granulose. Propodeum ( Fig. 8C ) granulose; area basalis trapezoid; area superomedia confluent with area petiolaris; all carina weakly developed; propodeal spiracle oval, connected to pleural carina by a distinct carina.

Vein 1cu-a opposite of M& RS. External angles of second discal cell acute (60°). Hind wing with CU&cu-a inclivous, intercepted at lower 0.15.

Legs. Hind femur 5.4× longer than wide. Inner spur of hind tibia ca. 0.5× as long as first tarsomere of hind tarsus. Tarsal claws weakly pectinate basally.

Metasoma. First segment ( Fig. 8H ) with glymma, ca. 3.0× longer than width of postpetiole; petiole ca. 1.25× longer than postpetiole. Second tergite ca. 1.15× longer than first tergite, 2.2× longer than its apical width; thyridium oval, its distance from basal margin of tergite ca. 5.5× its length. Third tergite 1.6× its apical width. Sixth and seventh tergites with a deep emargination dorso-medially. Ovipositor ( Fig. 8D ) very long and thin, slightly longer than length of metasoma, with a subapical notch on upper valve.

Colour. Black. Scape and pedicel blackish brown, mandible except teeth and tegula yellow; fore and mid coxae apically, trochanters and trochantelli pale whitish, coxa basally yellowish brown, remainder of fore leg yellowish brown with apical tarsomere darker; hind coxa, trochanter and femur extreme basally, blackish, trochantellus, femur and tibia medially yellowish brown, tibia basally and apically infuscated, tarsomere blackish brown; metasoma wholly black.
