Nannocharax signifer, new species, is described from the Ouémé River basin in Benin. It is distinguished from all other Nannocharax species in West Africa by its red-orange colouration on the anterior half of the dorsal fin. Besides live colouration, the new species is diagnosed by a combination of colour pattern and scale counts.
