Ictinogomphus fraseri Kimmins, 1958

Male is similar to I. regisalberti by (a) being very dark, with labrum black with 2 large central pale spots, black band across clypeus, and apices of vertex black; (b) cerci with strongly up-curved apex and sharp ventral angle. However differs by (1) being confined to forested rivers from Sierra Leone to Gabon; (2) broken antehumeral stripe; (3) posterior hamule without an internal hollow bearing a dense hair tuft; (4) cerci all dark, not broaldy pale dorsally.

Habitat description
