Synodontis woleuensis, a new species of mochokid catfish, is described from the Woleu/Mbini/Uoro and Ntem basins of Gabon and Equatorial Guinea. This relatively small species (<70 mm SL) is among the few Synodontis species with well-developed serrations along the anterior margin of the dorsal spine. It can further be distinguished from all congeners by a distinctive pigmentation pattern consisting of a dark background with numerous, small and irregular light spots, a pair of light spots anterior and posterior to the adipose fin, and a narrow, depigmented, curved band along the anterior margin of the caudal fin.

New taxon: Synodontis woleuensis Friel and Sullivan
