Crenigomphus cornutus Pinhey, 1956
Horned Talontail

Type locality: Victoria falls, Zambezi, Zambia

Diagnosis

Male is similar to C. kavangoensis by (a) S8-9 without foliations; (b) cerci curved toward each other in dorsal view, with wide space between them; (c) epiproct with dorsal teeth near apex, and wide notch between very short branches. However, differs by (1) ranging from Katanga to Namibia and South Africa; (2) cerci slightly longer than epiproct and about as long as S10, rather than cerci being distinctly longer than epiproct.
