Lestinogomphus calcaratus Dijkstra, 2015
Spurred Fairytail

Type locality: Negage, Canuango River, Angola

Diagnosis

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.
