Redescription.

Female. Length of body about 2.4 mm (Fig. 3 A View Figure 3 ). Length of forewing 1.7–1.9 mm (Fig. 3 K View Figure 3 ).

Head. Head weakly wider than metasoma (head and mesoscutum width ratio = 1.1) with sparse long setae. Eyes oval, sparsely setose. Face with densely long setae, width / height ratio 1.2–1.4 (Fig. 3 D View Figure 3 ). Tentorial index 0.4–0.5 (Fig. 3 D View Figure 3 ). Clypeus oval with 12 long setae. Malar space 0.2 times longitudinal eye diameter (Fig. 3 D View Figure 3 ). Antenna 11 - segmented (Fig. 3 B View Figure 3 ). F 1 equal to F 2 (Fig. 3 C View Figure 3 ). F 1 and F 2 3.4–4.4 (average 3.9) and 3.4–4.2 times (average 3.8) as long as their width at the middle, respectively. F 1 with two longitudinal placodes and F 2 with three longitudinal placodes. Maxillary palp with four palpomeres, labial palp with two palpomeres.

Mesosoma. Mesoscutum with notaulices on anterolateral margin, effaced dorsally; Dorsal surface smooth, with four rows of long setae (5–8 setae per row) arranged along the dorsolateral parts of the mesoscutum, with two rows on each side (Fig. 3 E View Figure 3 ). Scutellum nearly triangular, bearing 4 long setae on each side of dorsolateral. Propodeum areolated, areola length / width ratio is 1.5–1.8 (average 1.7) (Fig. 3 F View Figure 3 ). Pterostigma 3.0 times as long as width. Pterostigma longer than vein R 1 (= metacarpus) 1.7–2.0 (average 1.8) times. Vein r and RS extended.

Metasoma. Petiole long and slender, 3.2–3.4 (average 3.3) times as long as wide at level of spiracles and 3.1–3.3 (average 3.2) times as long as wide at level of secondary tubercles. Distance between spiracular and secondary tubercles is 2.6–2.9 (average 2.8) times as long as width at level of spiracular tubercles. Distance between secondary tubercles and apex of petiole is 1.2–1.3 (average 1.2) times width at level of secondary tubercles. (Fig. 3 I, J View Figure 3 ). Dorsolateral part of anterior spiracles is concave on each side (Fig. 3 I View Figure 3 ). Ovipositor sheath slender and long, curved downwards. Ratio of ovipositor sheath width / length is 2.2 at the base (Fig. 3 G View Figure 3 ). Prong is long, quite curved upwards, having one claw like bristle with 2 short setae and 9 setae at dorsal side (Fig. 3 G, H View Figure 3 ).

Colour. Antenna partly brown; scape, pedicel, F 1, 2 (at least partly yellowish brown at F 2) and F 7–9 yellowish brown, F 3–6 brown. Head black, face brown, clypeus with mouthparts yellowish brown. Mesosoma yellowish brown and metasoma brown; Mesonotum black; Petiole yellowish brown; Sternite 2–4 and part of sternite 5 is brown; part of sternite 5 and others, and ovipositor sheath with prong are yellowish brown. Legs light brown with dark apices.
