( Figs 2 , 11 , 28–32 , 62)

Description. Female. Moderately small species with body length 3.0– 3.3 mm and fore wing length 2.5–3.0 mm. Head in dorsal view roundly tapered behind eyes, with gena 0.8–0.9× as long as eye width (Fig. 30). Head entirely densely granulate, dull and impunctate except for smooth clypeus which is finely but distinctly punctate in upper half and sometimes slightly scabrous near upper margin. Clypeus lenticular, weakly convex, separated from face by sharp groove. Flagellum robust, filiform, with 15–17 flagellomeres (16 in holotype); subapical flagellomeres slightly transverse to weakly elongated (Fig. 29). Mandible with upper tooth somewhat longer than the lower. Malar space about 0.9× as long as basal mandibular width (Fig. 31).

Mesosoma entirely densely granulate, impunctate, dull. Notaulus with distinct longitudinal wrinkle on anterolateral side of mesoscutum. Foveate groove thin and short, slightly oblique to almost horizontal, extending somewhat before centre of mesopleuron. Propodeal spiracle small, separated from pleural carina by 1.0–2.0× diameter of spiracle. Propodeum mediodorsally with weak longitudinal (or partly irregular) wrinkles; basal part 0.5–0.7 as long as apical area; transverse carina well developed; apical area widely rounded anteriorly; apical longitudinal carinae complete. Fore wing ( Fig. 2 ) with vein 2m-cu weakly antefurcal or interstitial, unpigmented anteriorly, with posterior end distinct.

First tergite in lateral view with upper margin weakly arcuate or almost straight in basal 2/3 and convex in apical 1/3 ( Fig. 28 ); tergite almost entirely longitudinally striate, postpetiole dorsally in centre granulate and narrowly smooth on posterior margin. Glymma deep, situated in centre or slightly behind centre of tergite, with furrow between glymma and ventral part of postpetiole distinct to almost completely obliterated. Second tergite slightly elongated, about 1.1× as long as anteriorly broad. Thyridial depression shallow, about 1.5× as long as broad. Ovipositor robust, weakly and evenly upcurved, with weak dorsal subapical depression ( Fig. 32 ); sheath 1.1–1.4× as long as hind tibia.

Head and mesosoma dark reddish brown to black with reddish orange to red-brown markings ( Figs 11 , 28 ); palpi, mandible (teeth dark red), clypeus (except extreme upper margin) and tegula brownish yellow. Scape and pedicel of antenna yellow-brown; flagellum dark brown to black. Pterostigma brown. Legs predominantly brownish yellow; hind coxa dark brown; sometimes fore and mid coxae, hind femur and apical part of hind tibia also darkened with brown; all tarsi more of less infuscate. First metasomal tergite dark brown to brownish black, with apical end sometimes reddish brown. Metasoma posterior to first tergite yellowish brown to dark brown.

Male. Unknown.
