Eye in lateral view 1.1 times as high as wide and 3.0 times as wide as temple medially. POL 0.9 times OD; OOL 3.3 times OD. Face 1.2 times as wide as high, with sparse setae; inner margins of eyes subparallel. Clypeus 3.3 times as wide as high. Anterior tentorial pits short, far not reaching inner border of eye. Mandible almost parallel-sided, 1.7 times as long as its maximum width. Upper tooth wide; middle tooth rather narrow and long; lower tooth wide. Antennae 19-segmented, 1.5 times as long as body. Scape 1.2 times as long as pedicel. First flagellar segment 2.9 times as long as its apical width, 0.5 times as long as 2 nd segment. Second flagellar segment 6.1 times, 3 rd segment 5.2 times, 4 th– 6 th segments 4.8 times, 7 th– 10 th segments 4.4 times, 11 th– 16 th segments 4.0 times and 17 th (apical segment) 4.4 times as long as their maximum width.

MESOSOMA. In lateral view 1.2 times as long as high. Mesoscutum (in dorsal view) 0.9 times as long as its maximum width, smooth, sparsely setose. Notauli mainly absent on horizontal surface of mesoscutum. Mesoscutal pit present, round. Prescutellar depression smooth, with only median carina, 1.5 times as long as its maximum width. Precoxal sulcus present, weakly crenulate, not reaching anterior and posterior margins of mesopleuron. Posterior mesopleural furrow smooth. Propodeum weakly and sparsely sculptured, with several smooth patches, with large, wide and mainly smooth pentagonal areola; basolateral areas smooth. Propodeal spiracle small, its diameter 0.3 times distance from spiracle to anterior margin of propodeum.

WINGS. Length of fore wing 2.8 times its maximum width. Marginal cell ending at apex of wing, 3.7 times as long as its maximum width. Vein r longer than pterostigma width. Vein 3-SR 4.8 times as long as vein r and 2.4 times as long as vein 2-SR. Vein SR1 2.3 times as long as vein 3-SR. Hind wing 6.5 times as long as its maximum width.

LEGS. Hind femur 4.0 times as long as its maximum width. Hind tibia weakly widened to apex, 10.0 times as long as its maximum subapical width, about as long as hind tarsus. First segment of hind tarsus 1.9 times as long as 2 nd segment.

COLOUR. Body, antennal flagellar segments (except apically), mandible, and pterostigma brown. Legs light brown. Last six apical segments of antennae paler than other segments. Head and mesoscutum in dorsal view similarly coloured. First metasomal tergite paler than 2 nd and 3 rd tergites. Wings almost hyaline.

VARIATION. Body 1.5–1.8 mm, fore wing 1.7–2.0 mm, hind wing 1.0– 1.3 mm.Antennae 19–20-segmented. First flagellar segment 2.8–3.0 times and 2 nd segment 6.0–6.2 times as long as their maximum width. Hind femur 3.9–4.0 times as long as its maximum width.
