2.4 mm
. Body (
Fig. 1
) dark green except gaster and ovipositor sheaths black-brown. Mandible brownish yellow; eye pale pink, ocelli transparent. Antenna dark brown except scape brownish yellow. Wings hyaline, fore wing with dark brown below parastigma, V-shaped band below stigmal vein, and an additional band apically (
Figs 5
,
16
). Legs with coxae concolorous with mesosoma; fore and mid femora and tibiae yellowish brown; hind femur, tibia and all claws dark brown. Ovipositor sheaths black-brown, ovipositor brownish yellow.
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.
MALE. Unknown.
