Marcusenius kaninginii, a new Marcusenius species with eight large circumpeduncular scales, is described from the Lowa River, a right bank tributary of the Lualaba (Upper Congo basin). It is distinguished from all other Mar- cusenius species with eight circumpeduncular scales by the following unique combination of characters: 43-47 lateral line scales; 18-23 dorsal-fin rays; 27-30 anal-fin rays; 42-44 vertebrae; a relatively shallow body at the anterior base of the anal fin (depth 25.0-28.6 % SL); a deep caudal peduncle (39-57 % of caudal peduncle length); and a short pectoral fin (15.5-19.1 % SL). Additionally, it has a typical dark-brown body coloration with a black transversal bar between the anterior parts of the dorsal and anal fins, and a black horizontal band along the lat- eral line from just behind the opercle up to the transversal bar.


Marcusenius kaninginii, une nouvelle espèce de Marcusenius à huit écailles autour du pédoncule caudal, est décrite de la rivière Lowa, un affluent de la rive droite du Lualaba (bassin du Congo Supérieur). Il se distingue des autres Marcusenius à huit écailles autour du pédoncule caudal par la combinaison unique des caractères suivants: 43-47 écailles sur la ligne latérale; 18-23 rayons à la dorsale; 27-30 rayons à l’anale; 42-44 vertèbres; corps relativement moins élevé à la base antérieure de la nageoire anale (hauteur 25,0-28,6 % LS); un pédoncule caudal haut, (39- 57 % de la longueur du pédoncule caudal); et une nageoire pectorale courte (15,5-19,1 % LS). De plus, il présente une coloration corporelle typique noire-brunâtre avec une bande transversale noire entre les parties antérieures des nageoires dorsale et anale ainsi qu’une bande noire horizontale le long de la ligne latérale allant de l’opercule jusqu’à la bande transversale.

Nine out of 37 recognized species in the genus Marcusenius have eight large circumpeduncular scales rather than 12 or 16, which is more typical of the genus. They are: M. dundoensis, M. fuscus, M. ghesquierei, M. intermedius, M. kutuensis, M. lambouri, M. moorii, M. paucisquamatus and M. schilthuisiae. All nine are restricted to West-Central and Central Africa. A detailed morphometric analysis could not distinguish differences between M. moorii, M. paucisquamatus and M. lambouri. Therefore they are considered as synonyms with M. morrii as the senior synonym. The systematic status of M. intermedius is uncertain owing to the existence of only three specimens. Within this species complex a new species, Marcusenius sanagaensis, is described from the Sanaga River basin in Cameroon. It differs from all the others in the number of scales on the lateral line and in the extent of the broad dark band between the anterior base of the dorsal fin and the anterior base of the anal fin. All valid Marcusenius species with eight circumpeduncular scales are redescribed and a key to these species is given.
