Diagnosis. This species is easily distinguished from other Oriental species of the genus by elongate flagellomeres (Fig. 8), presence of second recurrent vein in forewing, distinctly punctate mesopleuron, and propodeal spiracle separated from pleural carina by 3.1× diameter of spiracle.

Description. Male. Body length 5.3 mm. Forewing length 2.8 mm.

Mandible with upper tooth distinctly longer than lower tooth (Fig. 4). Clypeus 2.6× as broad as long, with fine and sparse punctures (Fig. 4). Malar space 0.4 × basal width of mandible (Fig. 4). Flagellum of antenna with 16 flagellomeres, very slender, second flagellomere 4.3×as long as broad, and subapical flagellomere 2.0× as long as broad (Fig. 8). Face, frons and vertex granulate, dull or weakly shining (Figs 3, 4). Compound eyes very large, rather convergent above antennae (Figs 1– 4). Occipital carina mediodorsally absent.

Mesosoma very finely granulate (partly almost smooth) and indistinctly punctate, dull to weakly shining. Foveate groove of mesopleuron well developed, extending across anterior 0.7 of mesopleuron (Fig. 5). Propodeum with basal area narrow, distinctly widened anteriorly, 0.4× as long as apical area (Fig. 7). Propodeal spiracle separated from pleural carina by about 3.1× diameter of spiracle (Fig. 7). Apical area more or less flat.

Forewing with second recurrent vein. Without brachial cell. Hind wing with nervellus slanted about 35° from horizontal.

Legs moderately slender; hind femur 5.4× as long as broad.

First tergite 11.1× as long as posterior broad, its upper margin in lateral view (Fig. 6) straight in basal 0.8 and weakly rounded posteriorly. Second tergite about 2.8× as long as anterior broad.

Body mostly black (Figs 1–9). Head black. Clypeus yellowish-brown. Mandible yellowish-brown, with teeth blackish-brown. Maxillary and labial palpi yellowish-brown. Antenna yellowish-brown, with flagellomeres 7–14 brown to blackish-brown (Figs 8, 9). Mesosoma and first metasomal segment black. Tegula blackish-brown. Pterostigma brown. Legs yellowish-brown (Fig. 9). Metasoma behind first metasomal segment brown to blackish-brown, and yellowish-brown posteriorly (Fig. 6).

Female. Unknown.
