  • vernacular: Southern Gorgeous Skimmer

Type locality: Bolama, Guinea

Diagnosis

Male is similar to A. palustris by (a) fairly small size, Hw 22-27 mm; (b) labium uniformly pale yellow to brown, at most darkened on central lobe; (c) thorax marked with black stripes on humeral and metapleural sutures and Abd with broad black dorsal band and narrow lateral ones (all pruinose with maturity); (d) Fw triangle of 2 cells, subtriangle of 3-4, but both sometimes just of 1; (e) distal Ax in Fw often complete; (f) costa dark, like subcosta and anterior vein of Pt; (g) subcostal cross-veins pale, contrasting with dark subcosta and median vein; (h) tibiae black with pale yellow or brown streaks; (i) hind femur with 15-25 denticles in outer anterior row; (j) Abd broad, S3 at most 1.5x as long as wide (dorsal view); (k) venter of Abd yellow to pale brown. However, differs by (1) wings clear rather than amber, and at most small yellow patch at base and slightly darkened tips; (2) mostly 2 rows between anal loop and tornus, 4 between Rspl and posterior wing border.
