Eye in lateral view 1.2 times as high as wide and 1.7 times as wide as temple medially. POL 1.3 times OD; OOL 3.3 times OD. Face 1.5 times as wide as high; inner margins of eyes subparallel. Clypeus 2.5 times as wide as high, slightly concave ventrally. Anterior tentorial pits short, far not reaching inner border of eye. Mandible 1.7 times as long as its maximum width. Upper tooth wide; middle tooth rather narrow and long; lower tooth wide. Antennae 20-segmented, 1.2 times as long as body. Scape 1.2 times as long as pedicel.

MESOSOMA. In lateral view 1.3 times as long as high. Mesoscutum (in dorsal view) 0.9 times as long as its maximum width, smooth. Notauli mainly absent on horizontal surface of mesoscutum. Mesoscutal pit present, oval. Prescutellar depression smooth, with only median carina, 1.2 times as long as its maximum width. Precoxal sulcus present, crenulate, not reaching anterior and posterior margins of mesopleuron. Posterior mesopleural furrow smooth. Propodeum weakly and sparsely sculptured, with several smooth patches, with large, narrow and mainly smooth pentagonal areola; basolateral areas smooth, sparse rugose along carinae. Propodeal spiracle small, its diameter 0.5 times distance from spiracle to anterior margin of propodeum.

WINGS. Length of fore wing 2.6 times its maximum width. Marginal cell ending at apex of wing, 3.7 times as long as its maximum width. Vein r as long as pterostigma width. Vein 3-SR 4.2 times as long as vein r and 1.8 times as long as vein 2-SR. Vein SR1 2.3 times as long as vein 3-SR. Hind wing 6.2 times as long as its maximum width.

LEGS. Hind femur 4.8 times as long as its maximum width. Hind tibia weakly widened to apex, 10.0 times as long as its maximum subapical width and 1.3 times as long as hind tarsus. First segment of hind tarsus 2.0 times as long as 2 nd segment.

METASOMA. First tergite weakly widened towards apex, 1.2 times as long as its apical width, weakly striate. Visible part of ovipositor sheath 2.0 times as long as 1 st tergite, 0.8 times as long as metasoma, as long as hind femur.

COLOUR. Mesosoma, metasoma, antennae and pterostigma brown to dark brown. Head, mandible and legs light brown. Head and mesoscutum in dorsal view similarly coloured. First metasomal tergite paler than 2 nd and 3 rd tergites. Wings almost hyaline.

VARIATION. Body 1.9–2.1 mm, fore wing 1.9–2.1 mm, hind wing 1.2–1.3 mm.Antennae 19–20-segmented. First flagellar segment 2.6–2.8 times and 2 nd segment 3.3–3.5 times as long as their maximum width. Hind femur 4.8–5.0 times as long as its maximum width.

Male

Length. Body 1.6–1.8 mm, fore wing 1.7–1.9 mm, hind wing 1.4 mm. Antennae 20-segmented.
