Pseudagrion (A) aguessei Pinhey, 1964
Type locality: Kamabai, Sierra Leone
Male is similar to P. kibalense by (a) face greenish to blue-violet, turning dark with age or preservation; (b) postocular spots bluish, occiput black; (c) postclypeus all black; (d) thorax sides bluish, almost lacking interpleural stripe, or pruinose with maturity; (e) entire dorsum of S7 black, rarely with small apical marking (in which case antehumeral stripe often half as wide as mesepisternum); (f) cerci with lower branch not bent inwards but in line with upper branch lower branch bearing flange that ends with 1-2 teeth near base; (g) cerci with single tooth at basal end of flange. However, differs by (1) occurring at savanna streams from South Sudan to W Africa; (2) antehumeral stripe narrower than half-width mesepisternum; (3) interpleural and metapleural stripes more similar, but obscured by white pruinosity with maturity; (4) flange of cerci with blunt, rather than acute tooth at basal end.

Not known well, but probably rivers or streams shaded by gallery forest. Probably often with emergent vegetation. Inferred to occur from 200 to 600 m above sea level.
