Anterior and posterior transverse carinae of propodeum complete. Pleural carina and lateral longitudinal carina of propodeum complete. Area basalis distinct. Area superomedia indistinct laterally. Anterior part of propodeum densely punctate. Median and posterior parts of propodeum longitudinally, obliquely, and irregularly rugulose. Propodeum without projections.

Hind femur 4.2–4.6 times as long as maximum depth in lateral view. Hind TS I: II: III: IV: V = 2.0: 1.0: 0.6: 0.35–0.4: 0.4–0.5. Tarsal claws simple.

Metasoma. T I 1.3–1.4 times as long as maximum width, densely punctate. Median dorsal carina of T I present except for posterior part. Dorsolateral carina of T I complete. T II to T IV wider than long, densely punctate (Fig. 44C). T V to T VII covered with fine punctures. T VII and T VIII weakly elongated. Ovipositor sheath 0.75 times as long as hind tibia, its apical part distinctly expanded (Figs 44E, 66O). Ovipositor straight, compress laterally, with a nodus and ventral teeth (Fig. 66N).

Coloration (Figs 44A–E). Body (excluding wings) black to blackish brown. Mandible yellowish brown except for darkened apex and base. Fore and mid femora, tibiae. and tarsi more or less tinged with yellowish brown to reddish brown. Base of tibiae white. Tibial spurs whitish yellow. Membranous part of metasomal sternites yellowish brown. Ovipositor reddish brown. Wings hyaline. Veins and pterostigma brown to blackish brown.
