Type locality: Elisabethville [= Lubumbashi], DRC

Diagnosis

Male is similar to A. basilewskyi and A. bella by (a) small size, Hw 19-25 mm; (b) labium at least with contrasting black markings on most of central lobe and inner border of lateral lobes; (c) thorax with contrasting dark and pale markings, including 1-2 pale stripes on mesepisternum and complete black metapleural stripe; (d) Fw triangle and subtriangle both of 1 cell, but both sometimes of 2; (e) Abd slender, S3 at least 2x as long as wide. However, differs by (1) frons pale, narrowly black at base, rather than its dorsum being black; (2) black interpleural stripe ends just dorsal of metastigma; (3) mesepisternum with 2 pale stripes, rather than 1; (4) costa and subcostal Ax pale rather than dark, contrasting with dark subcosta and median vein; (5) hook of hamule small rather than large and broad, with anterior profile of hamule weakly concave.
