Female (holotype)

Length. Body 1.7 mm, fore wing 1.8 mm, hind wing 1.2 mm.

HEAD. In dorsal view, 1.6 times as wide as long, 1.5 times as wide as mesoscutum, smooth, with temple rounded behind eyes. Eye in lateral view 1.2 times as high as wide and 1.8 times as wide as temple medially. POL 1.2 times OD; OOL 4.4 times OD. Face 1.2 times as wide as high; inner margins of eyes subparallel. Clypeus 2.5 times as wide as high. Anterior tentorial pits short, far not reaching inner border of eye. Mandible almost parallel-sided, 1.6 times as long as its maximum width. Upper tooth wide; middle tooth rather narrow and short; lower tooth wide. Antennae 21-segmented, 1.5 times as long as body. Scape 1.2 times as long as pedicel. First flagellar segment 3.0 times as long as its apical width, 0.6 times as long as 2 nd segment. Second flagellar segment 5.4 times, 3 rd– 6 th segments 4.0 times, 7 th– 11 th segments 3.6 times, 12 th– 13 th segments 3.3 times, 14 th– 20 th segments 2.8–3.0 times and 21 st segment (apical segment) 2.5 times as long as its 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. Notauli mainly absent on horizontal surface of mesoscutum. Mesoscutal pit present, round. Prescutellar depression smooth, with only median carina, 1.3 times as long as its maximum width. Precoxal sulcus present, smooth, 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, 3.6 times as long as its maximum width. Vein r as long as pterostigma width. Vein 3-SR 6.7 times as long as vein r, 2.8 times as long as vein 2-SR. Vein SR1 2.2 times as long as vein 3-SR. Hind wing 6.0 times as long as its maximum width.

LEGS. Hind femur 5.2 times as long as its maximum width. Hind tibia weakly widened posteriorly, 9.5 times as long as its maximum subapical width, 1.1 times as long as hind tarsus. First segment of hind tarsus 1.7 times as long as 2 nd segment.

METASOMA. First tergite weakly widened posteriorly, as long as its apical width, weakly striate. Visible part of ovipositor 2.7 times as long as 1 st tergite, 0.8 times as long as metasoma, 1.4 times as long as hind femur.

COLOUR. Body, mandible, flagellar segments of antennae and pterostigma brown. Legs yellow. The last six apical segments of antennae whitish. Head and mesoscutum in dorsal view similarly coloured. Firstthird metasomal tergites similarly coloured. Wings almost hyaline.

VARIATION. Body 1.6–1.8 mm, fore wing 1.8–2.0 mm, hind wing 1.1–1.3 mm.Antennae 18–22-segmented. The last four–seven apical segments paler than preceding segments. First flagellar segment 3.0–3.1 times as long as its maximum width. Second flagellar segment 5.5 times as long as its maximum width. Hind femur 5.0–5.2 times as long as its maximum width.

Male

Length. Body 1.3–1.4 mm, fore wing 1.3–1.4 mm, hind wing 1.1 mm. Antennae 20–21-segmented. First flagellar segment 3.5–3.7 times as long as its maximum width. Second flagellar segment 5.6–6.0 times as long as its maximum width. Third flagellar segment 6.0 times as long as its maximum width. Hind femur 4.8–5.0 times as long as its maximum width. Otherwise similar to female.

Comparative diagnosis

This new species is similar to A. taylori sp. nov., but differs from it in having the clypeus 2.5 times as wide as high (2.0 times in A. taylori sp. nov.), 2 nd flagellar segment 5.4 times as long as its maximum width (4.9 times in A. taylori sp. nov.), 3 rd segment 4.8 times (3.7 times in A. taylori sp. nov.), 1 st metasomal tergite as long as its apical width (1.3 times in A. taylori sp. nov.), visible part of ovipositor 2.7 times as long as 1 st tergite (same length in A. taylori sp. nov.), 0.8 times as long as metasoma (0.4 times in A. taylori ), and 1.4 times as long as hind femur (0.7 times in A. taylori sp. nov.).

Distribution
