Crenigomphus denticulatus Selys, 1892
Type locality: Kobbo, Shoa, Ethiopia
Male is closest to C. hartmanni by (a) S8-9 with foliations which are often bordered with black; (b) dorsum S10 flat; (c) branches of epiproct taper to very slender apices, appearing like nib of fountain pen. However, differs by (1) being restricted to Ethiopia; (2) smaller size, Hw about 24 mm; (3) S10 about 2x as long as S9; (4) cerci straight, in lateral view most clearly curved at apex, in dorsal view parallel with narrow space between them (rather than gradually curved); (5) epiproct strongly rather than weakly up-curved, usually projecting beyond cerci in lateral view.

Not known, but probably rivers or streams in open landscapes. Probably especially faster sections with bare banks, rocks and a gravelly and/or sandy bottom. From 1000 to 2900 m above sea level.
