Lestinogomphus calcaratus Dijkstra, 2015
Type locality: Negage, Canuango River, Angola
Male recalls L. angustus by (a) the pair of large teeth near the base of the epiproct dorsum. However, (1) is much darker overall, with a black band on the fronto-clypeal suture and a thick black rim to the labrum, the pale area on the collar not extending posteriorly of the middorsal tooth, the humeral and interpleural black stripes thick and enclosing a narrow green stripe, the metapleural black stripe also thick, and the tibiae black without pale streaks; (2) the distal border of the posterior hamule is shallowly notched, rather than almost straight; (3) S10 is shorter, its dorsal length is 1.4-1.7x its apical height, rather than 1.7-2.2x; (4) the curved portions of the cerci bear a small external lobe subapically; and (5) the subbasal teeth of the epiproct have a narrower base, thus appearing sharper and leaning into S10.

Mostly streams but also rivers in open areas in forest or shaded by gallery forest, possibly also in more open and forested areas. Probably often with a gravelly and/or sandy bottom, and/or overhanging bushes. From 300 to 1300 m above sea level.
