Description.

Female. Habitus as in Fig. 4C. Body not compact, not flattened. Body length 1.25 mm.

Coloration. Body, antennae, gaster dorsally and ventrally dark, without metallic shine, monotonously shallow reticulate; pronotum, mesoscutum, and scutellum clothed in more long setae.

Head. Hypognathous, wider than its length, slightly wider than thorax, with rounded occipital margin (Fig. 5B); eyes bare, with inner orbits rather slightly divergent (Fig. 4D); OOL equal to posterior ocellar diameter; OCL about twice as long as posterior ocellar diameter; eye reaching occipital margin; interantennal projection small but visible in lateral view (Fig. 4A); toruli located at level of lower margin of eyes (Fig. 4A); malar sulcus complete; height of eye about twice larger than malar space; mandibles narrow, probably two-toothed (Figs 4A, C; 5A).

Antenna. 11-segmented (1:1:6:3); radicle short, twice as long as broad; scape long, about 5 × as long as broad (Fig. 4A); pedicel conical, as long as F1 and F2 combined, longer than any segment of funicle; funicle not flattened, width of flagellomeres slightly increases toward apex; all segments of funicle and clava with mps (Fig. 4A); clava with small oblique truncation on rounded apical segment (Fig. 4A), slightly wider than F6; flagellum and clava clothed in short setae.

Mesosoma. Pronotum short, almost vertical, in dorsal view without transverse dorsal surface (Fig. 5B); mesoscutum about as broad as long; axillae transverse-triangular with anteromedial angles contiguous; prepectus large, bare, polygonally reticulate (Fig. 5B); acropleuron convex, bare, with shallow longitudinal reticulate sculpture, long; subtegular region of acropleuron large, convex, delineated by distinct sulcus; metapleuron and propodeum without visible setation (Fig. 4C).

Wings. Fully developed. Fore wing with costal cell narrow; submarginal vein without extension; hyaline break present; setation of linea calva in holotype poorly visible (Fig. 5C); marginal vein 0.5 × as long as stigmal one; proportions of forewing venation as in Fig. 5C; stigmal vein with long narrow uncus, consisting row of uncal sensillae; postmarginal vein with row of long setae; setae of marginal fringe present (Fig. 5C).

Legs. Normal in size, alike polygonal reticulate; protibia with long, curved, bifurcate calcar; strigil well-developed but distinct basitarsal comb absent (Figs 4C, 5A: st); tarsi 5-segmented; mesotibial spur slightly shorter than mesobasitarsus; metatibia with two spurs.

Gaster. As long as mesosoma, polygonal reticulate equal dorsally and ventrally; protruding part of ovipositor stylet approximately as long as metatarsus (in ovipositing position); suture between 1st and 2nd valvulae clearly visible at base and at apex of stylet (Fig. 5D).

Male. Unknown.
