Body pale yellow. Eye pale grey to greyish black; vertex creamy white tinged with pale yellow anteriad. Pronotum creamy white tinged with yellow at posterior half; fore wing semitransparent, smoky white, often tinged with yellow at clavus and costal margin, with yellow stripe on corium; hind wing transparent.

Head as wide as pronotum; vertex roundly produced, 1.6 times as wide as median length, 0.8 times as long as mesonotum; coronal suture short, 0.2–0.3 times as long as median length. Pronotum twice as wide as long, slightly longer than mesonotum. Male abdominal sternal apodemes broad and short, exceeding slightly posterior margin of 3rd sternite.

Body length (mean): ♂, 2.3–2.4 mm (2.4 mm); ♀, 2.5–2.6 mm (2.6 mm).

Male genitalia. Pygofer with lobe rounded caudally, bearing numerous setae scattered; dorsal process of pygofer short, slightly curved ventrad, sinuate in ventrad of apical half, obtuse apically. Subgenital plate with lateral margin angulate, bearing 4–5 basal macrosetae in oblique row and rigid marginal setae forming continuous row. Style widened and truncate apically, with preapical lobe distinct and apophysis short, 0.1–0.2 times as long as style. Connective roundly hexagonal, with posterior margin concave. Aedeagus compressed, strongly curved dorsad near base and gently re-curved, with elongate dorsal apodeme and pair of apical processes slender, extending laterally, slightly curved ventrad; shaft in caudal view broad, narrowed basal 1/3, concave in apical 2/3; gonopore subapex on caudal surface. Anal tube with basal process slender.

Remarks. This species is similar to A. medioborealis (Ghauri, 1980) described from Papua New Guinea in the shape of the male genitalia, but is distinguished by the following characters: aedeagal shaft in caudal view widened at basal 1/3 (not tapering from base to apex), with apical process slightly sinuate.
