Aciagrion brosseti Legrand, 1982
Type locality: Makokou, Gabon
Male is similar to A. steeleae by (a) smaller size, Hw 14-18 mm; (b) dorsum of head between eyes (almost) continuously black; (c) thorax with complete black middorsal and often humeral stripes; (d) cerci only about half as long as S10 but distinctly longer than paraprocts, with broad or rounded apex; (e) paraprocts with basal tooth directed straight upwards. However, differs by (1) ranging from C DRC to Gabon; (2) Pt blackish, rather than pale brown; (3) wings often yellowish, rather than clear; (4) S7 with blue subapical ring, rather than being dorsally evenly black; (5) S10 black rather than blue, and often with blue dorsal spot; (6) ventral process of cerci short, rather than slender.
