Africallagma pseudelongatum (Longfield, 1936)
Type locality: Birunga Mts, Kigezi district, Uganda
Male is similar to A. subtile by (a) Fw Pt diamond-shaped, opposite borders roughly parallel and of similar length, pale brown to black; (b) cerci distinctly longer than paraprocts with long apex abruptly separated from thumb-like ventral process (best seen in caudal view); (c) spine of paraprocts does not reach beyond bulge (at most slightly) or tip of cerci; cerci with dorsal border not or weakly excised; (d) base of paraprocts much swollen, resulting in prominent inferior bulge. However, differs by (1) ranging from W Kenya to Katanga; (2) larger size, Hw 18-19 mm; (3) Pt blackish, rather than pale brown with maturity; (4) legs with prominent black stripes, rather than entirely pale; (5) dorsum S2 blue with black subapical spot; (6) ventral process stands about at mid-point of cerci, rather than at base.

Standing and probably often temporary waters shaded by or in open areas in (gallery) forest. Often with emergent and usually aquatic vegetation and probably blackwater. From 900 to 2400 m above sea level, but possibly up to 3800.
