Trithemis dejouxi Pinhey, 1978
- scientific: T. donaldsoni (Calvert, 1899) ssp. dejouxi
Type locality: Ouham River, Bohira, Bouar, Central African Republic
Male is similar to T. donaldsoni by (a) 10½-12½ Ax in Fw, only rarely 13½; (b) Hw base at most with small brown patch, excluding triangle; (c) 3-4 rows between anal loop and tornus; (d) anterior lamina with tapering sides, apex pointed with narrow notch, peaks pale and often knob-like; (e) hamule like sickle; (f) genital lobe directed away from hamule. However, differs by (1) ranging from S Arabia to W Africa; (2) at least Hw usually with yellow wash (rather than wings all clear), base with small but distinct brown patch in cubital space; (3) venter of Abd all black rather than with pale spots.

Rivers in open landscapes. Especially faster sections (rapids, falls), usually with rocks. Inferred to occur from 0 to 1700 m above sea level.
