Diagnosis.

Body largely dull; vertex transversely striate (Fig. 218); frons with 3 yellowish streaks (Fig. 220); yellowish patch on temple weakly defined (Fig. 219); pygidial impression indistinct (Fig. 216); pronotum anteriorly with some fine rugulae, laterally coriaceous or finely reticulate (Figs 212, 213); scutellum matt and medially coriaceous (Fig. 214); pterostigma moderately elongate; vein 2-CU1 of fore wing absent (Fig. 211); both large teeth on hind femur mostly yellowish (Fig. 215); ovipositor sheath 0.9 as long as body length; subapical ivory band of ovipositor sheath 2.5 times as long as its blackish apex (Fig. 217).

Description.

Holotype, female, length of body 13.4 mm, of fore wing 6.7 mm, and of ovipositor sheath 11.6 mm.

Head. Flagellum with 29 flagellomeres; frons coarsely transversely striate (Fig. 220); coronal area rugose and coronal teeth acute; vertex slightly convex and finely transversely striate, striations posteriorly reaching occipital carina (Fig. 218); temples smooth and matt, narrowed and rounded behind eyes (Fig. 219).

Mesosoma. Neck (Fig. 212) elongate and rather robust, at about same level as middle pronotum, anteriorly distinctly emarginate, dorsally with weak transverse carinae, medio-longitudinally slightly impressed; middle pronotum transversely striate; posterior pronotum distinctly elevated and rugose dorsally, convex laterally (Fig. 213); mesoscutum anterior half densely striate and posteriorly coarsely foveolate; axillae coarsely rugose; scutellum largely smooth and matt, sparsely with a few punctures (Fig. 214); mesopleuron anterior 0.3 rugose and covered with setosity, remainder largely aciculate; convex part of metapleuron rather robust, largely strongly reticulate-foveolate; both anterior and ventral foveae large; propodeum largely spaced foveolate, foveolae medium-sized, circular and well defined, with microsculptured interspaces (Fig. 214).

Wings. Fore wing (Fig. 211): wing membrane hyaline; vein 2-CU1 weakly developed and 0.1 times as long as vein cu-a; pterostigma moderately elongate and somewhat rounded apically, 2.9 times as long as vein r and 13.7 times as its maximum width; vein r ends 0.2 times length of pterostigma behind level of apex of pterostigma; vein SR1 nearly parallel to costal margin, vein SR1 and vein r obtusely angled.

Legs. Hind coxa largely transversely striate, anterior 0.3 rugose; hind femur densely transversely strigate, ventrally with two large acute ivory teeth, basally with 2 obtuse tubercles (Fig. 215); hind tibia coriaceous, 1.2 times as long as hind femur, basal narrow part of hind tibia 1.1 times as long as widened part; inner side of widened part basally depressed, medially convex and granulate, apically densely setose (Fig. 216); length of basitarsus 5.0 times as its width and ventrally densely bristly setose.

Metasoma. First tergite finely transversely striate, 14.2 times as long as its maximum width, 2.2 times second tergite and 0.9 times remainder of metasoma; pygidial area indistinctly differentiated, apically truncate, laterally slightly impressed, medially weakly convex and granulate; subapical ivory band of ovipositor sheath 2.5 times as long as apical blackish part (Fig. 217); ovipositor sheath 0.9 times as long as body length.

Colour. Brownish to blackish; frons with 3 longitudinal yellowish streaks, one centrally and the other two along the inner orbits; temple ventrally brownish along eye; wing membrane hyaline, wing veins light brownish; pterostigma ivory; pronotum, hind femur and hind tibia, and metasoma largely dark brown; fore and middle legs largely brownish and with some whitish parts; large ventral teeth of hind femur ivory; subapical ivory band of ovipositor sheath 2.5 times as long as apical blackish part.

Male. Unknown.
