Female (holotype)

LENGTH. Body 2.6 mm, fore wing 3.0 mm, hind wing 2.1 mm.

HEAD. In dorsal view, 1.8 times as wide as long, 1.4 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 equal to OD; OOL 4.3 times OD. Face 1.8 times as wide as high, with sparse setae; inner margins of eyes subparallel. Clypeus1.8 times as wide as high, slightly concave ventrally. Anterior tentorial pits short, far not reaching inner border of eye. Mandible 1.6 times as long as its maximum width. Upper tooth wide; middle tooth rather wide and short; lower tooth wide. Antennae 22-segmented, 1.5 times as long as body. Scape 1.5 times as long as pedicel. First flagellar segment 3.0 times as long as its apical width, 0.5 times as long as 2 nd segment. Second flagellar segment 7.2 times, 3 rd– 4 th segments 5.0 times, 5 th– 6 th segments 4.5 times, 7 th– 9 th segments 4.0 times, 10 th– 13 th segments 3.3 times, 14 th– 19 th segments 2.8–3.0 times, 20 th (apical) segment 4.0 times as long as its maximum width.

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, elongate. Prescutellar depression smooth, with only median carina, 0.8 times as long as its maximum width. Precoxal sulcus present, crenulate, reaching anterior and posterior margins of mesopleuron. Posterior mesopleural furrow crenulate. Propodeum weakly and sparsely sculptured, with several smooth places, with large, narrow and mainly smooth pentagonal areola; basolateral areas smooth, sparse rugose along carinae. Propodeal spiracle small, its diameter 0.3 times distance from spiracle to anterior margin of propodeum.

WINGS. Length of fore wing 3.3 times its maximum width. Marginal cell ending at apex of wing, 3.8 times as long as its maximum width. Vein r longer than pterostigma width. Vein 3-SR 5.6 times as long as vein r and 3.1 times as long as vein 2-SR. Vein SR1 1.7 times as long as vein 3-SR. Hind wing 5.0 times as long as its maximum width.

LEGS. Hind femur 5.2 times as long as its maximum width. Hind tibia weakly widened to apex, 11.0 times as long as its maximum subapical width and 0.9 times as long as hind tarsus. First segment of hind tarsus 1.8 times as long as 2 nd segment.

METASOMA. First tergite parallel-sided, 2.3 times as long as its apical width, weakly striate. Visible part of ovipositor sheath 1.4 times as long as 1 st tergite, 1.1 times as long as metasoma and 3.3 times as long as hind femur.

COLOUR. Body, antennae (except apically) and pterostigma dark brown. Mandible and legs light brown. Eleven apical segments paler than preceding 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 2.4–2.6 mm, fore wing 2.7–3.0 mm, hind wing 1.9–2.1 mm.Antennae 21–22-segmented. First flagellar segment 3.0–3.1 times as long as its maximum width. Hind femur 5.0–5.2 times as long as its maximum width.

Male

Unknown.

Comparative diagnosis

This new species is similar to A. subdentata ( Granger, 1949) and A. harrinsmithensis sp. nov., but differs from them in having the face 1.8 times as wide as high (1.2 times in A. subdentata and 1.4 times in A. harrinsmithensisi sp. nov.), 1 st flagellar segment 3.0 times as long as its maximum width (3.9 and 4.5 times in A. harrinsmithensis sp. nov. and A. subdentata , respectively), 2 nd segment 7.2 times (8.3 and 5.8 times in A. harrinsmithensis sp. nov. and A. subdentata , respectively), 3 rd segment 5.8 times (6.7 and 3.3 times in A. harrinsmithensis sp. nov. and A. subdentata , respectively), and 1 st metasomal tergite 2.3 times as long as its apical width (1.4 and 1.5 times in A. harrinsmithensis sp. nov. and A. subdentata , respectively); additionally mesoscutal pit elongate (oval in A. subdentata ) and hind femur 5.2 times as long as its maximum width (5.8 times in A. harrinsmithensis sp. nov.).
