Description

Female (holotype)

LENGTH. Body 2.0 mm, fore wing 2.0 mm, hind wing 1.5 mm.

HEAD. In dorsal view, 1.6 times as wide as long, 1.4 times as wide as mesoscutum, smooth, with temple rounded behind eyes, with distinct longitudinal furrow in middle of vertex. Eye in lateral view as high as wide and 1.3 times as wide as temple medially. POL 1.4 times OD; OOL 3.3 times OD. Face 1.9 times as wide as high, with sparse setae; inner margins of eyes subparallel. Clypeus 1.9 times as wide as high. Anterior tentorial pits short, far not reaching inner border of eye. Mandible 2.0 times longer than its maximum width. Upper tooth wide; middle tooth rather wide and short, directed upwards; lower tooth wide. Antennae 24-segmented, 1.3 times longer than body. Scape 1.2 times as long as pedicel. First flagellar segment 3.1 times as long as its apical width, 0.6 times as long as 2 nd segment. Second flagellar segment 4.0 times, 3 rd– 4 th segments 3.1–3.3 times, 5 th segment 2.7 times, 6 th– 9 th segments 3.3 times, 10 th– 13 th segments 2.3 times, 14 th– 23 rd segments 1.9 times, 24 th (apical segment) 2.3 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, sparsely setose along notauli. Notauli mainly absent on horizontal surface of mesoscutum. Mesoscutal pit present, elongate. Prescutellar depression smooth, with median and lateral carinae, 2.0 times as long as its maximum width. Precoxal sulcus present, smooth, not reaching anterior and posterior margins of mesopleuron. Posterior mesopleural furrow entirely smooth. Propodeum sculptured, with several smooth patches, with large, wide and mainly smooth pentagonal areola; basolateral areas smooth, sparsely rugose along carinae. 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, 3.5 times as long as its maximum width. Vein r shorter than pterostigma width. Vein 3-SR 8.8 times as long as vein r, 1.8 times as long as vein 2-SR. Vein SR1 2.0 times as long as vein 3-SR. Hind wing 6.0 times as long as its maximum width.

LEGS. Hind femur 4.4 times as long as its maximum width. Hind tibia weakly widened to apex, 7.7 times as long as its maximum subapical width, about as long as hind tarsus. First segment of hind tarsus 2.2 times as long as 2 nd segment.

METASOMA. First tergite widened towards apex, about as long as its apical width, weakly striate. Visible part of ovipositor 2.7 times as long as 1 st tergite, 0.7 times as long as metasoma, 1.5 times as long as hind femur.

COLOUR. Body, antenna, metasoma and pterostigma brown. Legs, head lateral view, mandible, scapus and pedicel light brown. Head and mesoscutum in dorsal view similarly coloured, as are 1 st– 3 rd metasomal tergites. Wings almost hyaline.

VARIATION. Body 1.9–2.0 mm, fore wing 2.0– 2.1 mm.

Male

Unknown.

Comparative diagnosis

This new species is similar to A. natalensis sp. nov., but differs from it in having the precoxal sulcus remaining separated from anterior and posterior margins of mesopleuron (reaching in A. natalensis sp. nov.), 1 st metasomal tergite as long as its apical width (1.4 times in A. natalensis sp. nov.), vein m-cu antefurcal (interstitial in A. natalensis sp. nov.), and visible part of ovipositor sheath 0.7 times as long as metasoma in lateral view (equal to in A. natalensis sp. nov.).

Distribution

South Africa.
