Trithemis apicalis (Fraser, 1954)
- scientific: Anectothemis apicalis; Porpacithemis trithemoides Fraser, 1958
Type locality: Busu-Moto, DRC
Male is similar to T. leakeyi by (a) labrum often largely black; (b) Fw discoidal field partly of 2 cell-rows; 3 cell-rows between anal loop and tornus; (c) no cell-doublings in radial planate (count those cells touching Rspl, but not IR3) [0-1]; (d) arculus often at Ax2 or distal to it, especially in Hw; (e) Hw base clear, yellow or brown, colour is usually brown if it extends beyond Cux; (f) venation largely dark, brown to black, like veins of Pt; (g) hamule with posterior border humped, hook thereby shortened; (h) Abd largely black, often with some pale markings, appears blue pruinose or black with maturity; (i) cerci of normal proportions, ventral angle lies 1/3 of cercus length from apex. However, differs by (1) larger size, Hw 25-30 mm; (2) dorsum of frons glossy black rather than pale with black basal band; (3) Abd slender, S4 over 4x as long as wide; (4) at most S1-3 deep blue pruinose, like thorax.

Standing and often temporary waters, mostly in open areas in forest. Often boggy or with blackwater, a sandy bottom, and probably emergent vegetation and coarse detritus. From 300 to 1300 m above sea level.
