Africallagma pseudelongatum (Longfield, 1936)
Spotted Bluet

Type locality: Birunga Mts, Kigezi district, Uganda

Diagnosis

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.
