Notogomphus leroyi (Schouteden, 1934)
- scientific: N. butoloensis Fraser, 1952
- vernacular: Leroy's L.
Type locality: Uele, Bambesa, DRC
Male is similar to N. bosumbuli by (a) labrum black with large paired basal pale spots; (b) occiput black, at most with central pale spot; (c) thorax with broad, (nearly) complete inter- and metapleural stripes; (d) postdorsal and antehumeral stripes well-defined, separate from each other and pale area of middorsal carina; (e) anterior border of posterior hamule rather straight; (f) cerci somewhat convergent, with ventral tooth directed straight downwards, not visible in dorsal view; (g) branches of epiproct diverge strongly. However, differs by (1) ranging from W Kenya and W Tanzania to E DRC; (2) smaller size, Hw 31-34 mm; (3) Abd club-shaped rather than parallel-sided, S7-9 distinctly expanded, S8 about as long as high or wide; (4) S8-9 quite uniformly dark rufous, rather than yellow; (5) cerci distinctly widened subapically, rather than of even weight.

Mostly streams, but also rivers, shaded by forest. Often with a gravelly and/or sandy bottom and probably coarse detritus. From 500 to 1800 m above sea level.
