Female (holotype)

LENGTH. Body 1.9 mm, fore wing 2.1 mm, hind wing 1.4 mm.

HEAD. In dorsal view, 1.6 times as wide as long, 1.3 times as wide as mesoscutum, smooth, with temple rounded behind eyes. Eye in lateral view 1.2 times as high as wide and 2.7 times as wide as temple medially. POL 0.8 times OD; OOL 3.1 times OD. Face 1.1 times as wide as high; inner margins of eyes subparallel. Clypeus 3.0 times as wide as high. Anterior tentorial pits short, far from 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 22-segmented, 1.3 times as long as body. Scape 1.2 times as long as pedicel. First flagellar segment 3.8 times as long as its apical width, 0.7 times as long as 2 nd segment. Second flagellar segment 6.0 times, 3 rd segment 5.0 times, 4 th segment 4.5 times, 5 th– 7 th segment 4.2 times, 8 th– 10 th segments 3.7 times, 11 th– 21 st segment 4.0 times and 22 nd (apical segment) 4.5 times as long as its maximum width.

MESOSOMA. In lateral view 1.3 times as long as high. Mesoscutum (in dorsal view) 0.8 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, 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 areas, with large, wide and mainly smooth pentagonal areola; basolateral areas smooth. Propodeal spiracle small, its diameter 0.2 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, 3.5 times as long as its maximum width. Vein r longer than pterostigma width. Vein 3-SR 6.1 times as long as vein r, 2.5 times as long as vein 2-SR. Vein SR1 2.4 times as long as vein 3-SR. Hind wing 5.7 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, 7.4 times as long as its maximum subapical width, 1.1 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, 1.3 times as long as its apical width, smooth. Visible part of ovipositor sheath 4.2 times as long as first tergite, 1.2 times as long as metasoma, 2.0 times as long as hind femur.

COLOUR. Body, flagellar segments of antennae (except apically) and pterostigma brown to dark brown. Mandible, scapus, pedicel and legs yellow. Coxae, trochanter and last six apical segments of antennae white. 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 2.0– 2.3 mm, hind wing 1.4–1.6 mm. First flagellar segment 3.8–4.0 times and 2 nd segment 5.8–6.0 times as long as their maximum width. Hind femur 5.2–5.4 times as long as its maximum width.

Male

Length. Body 1.6–1.8 mm, fore wing 1.9–2.0 mm, hind wing 1.1–1.3 mm. First flagellar segment 5.5– 5.6 times as long as its maximum width; 2 nd segment 7.5–8.0 times and 3 rd segment 6.5–6.8 times as long as their maximum width. Hind femur 5.0 times as long as its maximum width. Otherwise similar to female.

Comparative diagnosis

This new species is similar to A. vanharteni sp. nov., but differs from it in having hind femur 5.2 times as long as its maximum width (4.0 times in A. vanharteni sp. nov.), 1 st flagellar segment 3.8 times as long as its maximum width in female (2.9 times in A. vanharteni sp. nov.), mesoscutal pit oval (round in A. vanharteni ), prescutellar depression as long as its maximum width (1.5 times in A. vanharteni sp. nov.), and visible part of ovipositor sheath 4.2 times as long as 1 st metasomal tergite in lateral view (3.2 times in A. vanharteni sp. nov.).

Distribution

Uganda.
