Head in dorsal view 1.8× as wide as long, vertex with fine transverse reticulation on posterior margin; anterior and posterior ocelli almost in same line, the posterior ocelli near occipital carina (Figs 3, 4); POL 2.4× OOL; temple 0.4× as long as eye length; occipital carina fine, reaching vertex. Head in anterior view about 1.1× as high as wide; upper face with shallowly engraved reticulation (Fig. 2); lower face with finely raised reticulation; scrobe distinct. Ventral margin of clypeus truncate; anterior tentorial pits indistinct, vertical suture between each pit and margin of mouth distinct; eye height 3.1× eye width and about 2.5× malar space; inner margin of eyes parallel; mandible tridentate. Antenna (Fig. 2) distinctly clavate, inserted at center of face; scape 0.8× as long as eye height, at most reaching anterior ocellus; combined length of pedicel and flagellum slightly greater than head width (at most 1.1×); anellus ring-like; funicle with fu1 shortest, transverse, about 0.5× as long as fu2, subsequent segments subquadrate to slightly transverse, and each funicular segment bearing one row of longitudinal sensilla; clava 1.9× as long as its greatest width and slightly longer than fu5–fu7 combined.

Mesosoma convex in lateral view (Fig. 1), as broad as or slightly narrower than head width. Pronotum with raised reticulation, pronotal collar 3.5× as wide as long, distinctly narrower than mesoscutum, with anterior edge of collar not carinate but sharply edged and distinctly emarginate medially (Figs 3, 4). Mesoscutum with raised reticulation; notauli complete and distinct (Fig. 4). Scutellum smooth, longer than wide; frenal line distinct in posterior 1/3 of scutellum. Propodeum rugose, median carina complete and distinct, and with several irregular longitudinal carinulae on either side; costula distinct and convex on lateral part of propodeum; spiracles almost touching hind margin of metanotum. Mesopleuron with mesepisternum reticulate; upper and lower mesepimeron smooth; transepimeral sulcus reduced to a single pit. Metapleuron smooth. Fore wing 2.5× as long as wide (Figs 5, 16); costal cell bare on upper surface and with three setae on ventral surface; basal cell and basal fold bare; subcubital setal line distinctly setose from speculum to apical margin of wing; marginal vein 11× as long as postmarginal vein; postmarginal vein very short, as long as stigmal vein. Hind coxa reticulate; hind femur slender, without ventral teeth (Fig. 1); hind tibia with two short spurs; basitarsus 0.3× as long as hind tibia.

Metasoma slightly shorter than mesosoma. Petiole reticulate and rugose on anterior half, petiole as long as hind coxa. Gaster arched (Fig. 1) in lateral view; dorsally smooth, 1.5× as long as wide; Gt1 with hind margin incised medially; Gt2 with hind margin M-shaped; Gt3 longest, about 0.7× as long as gaster; ovipositor sheaths 0.6× as long as gaster.
