Trithemis bifida Pinhey, 1970
Type locality: Mwinilunga, Zambia
Male is similar to T. donaldsoni and T. dejouxi by (a) dorsum of frons metallic blue or purple, occasionally pale, bronze or black; (b) Fw discoidal field of 3-4 rows; 3-4 rows between anal loop and tornus; all wings with 2-8 celldoublings in radial planate [0-8]; (c) arculus between Ax1-2, at most at Ax2 in Hw; (d) Hw base at most with small brown patch, excluding triangle; (e) hamule with long sickle-shaped hook; genital lobe directed away from hamule. However, differs by (1) being widespread, at sheltered streams; (2) 13½-16½ Ax in Fw [12½-16½]; (3) anterior lamina parallel-sided, apex broad with wide notch, peaks dark and rounded (caudo-ventral view); (4) hamule very slender, like sabre.

Streams in open areas in forest, but sometimes also shaded by gallery forest. Often with a sandy bottom, and probably especially calmer sections (like pools) with emergent vegetation, overhanging branches, submerged roots and/or coarse detritus. From 100 to 1600 m above sea level.
