A new procatopodid, assigned to the genus Poropanchax, is described from a wetland habitat located adjacent to the Inga Falls in Lower Congo. Poropanchax pepo, new species, is distinguished from all congeners by a combination of characters including a higher D/A ratio, rounded anal and dorsal fins, a humeral blotch in males, and the absence of a sharp ventral process on the basipterygium. The finding of a Poropanchax species in Lower Congo was unexpected, since the closest known congeneric population is located in northwestern Gabon, some 700 kilometers to the north. As recognized herein the genus Poropanchax is a clade comprised of five species geographically restricted to humid coastal regions of west and west-central Africa.
