Trithemis kalula Kirby, 1900
Type locality: Freetown, Sierra Leone
Male is similar to T. bredoi by (a) ranging from N DRC to W Africa; (b) labrum often largely pale; (c) vertex and dorsum of frons dark purplish metallic; (d) venation largely pale, yellow to red, often contrasting with black veins of Pt; (e) Hw base yellow, orange or amber, colour usually surpasses Cux but excludes triangle; (f) Abd broader, S4 at most 2x as long as wide; (g) Abd largely pale, with some black markings, appears orange, red, or pruinose violet with maturity; (h) anterior lamina pointed, often with plume of long hairs; (i) hamule with long, sickle-shaped hook; (j) at least S8 with broad black marking and S9 largely black. However, differs by (1) Pt brown to black, rather than yellow to pale brown, thus contrast with anterior black vein usually weak; (2) usually 11½-13½ Ax in Fw; (3) anterior lamina and hamule largely blackish rather than pale; (4) S4-8 at least partly with black laterally; (5) dorsum S8 (largely) pale rather than broadly black.
