Diagnosis: Marcusenius wamuinii can be distinguished from all small-scaled Marcusenius species by having 8 circumpeduncular scales vs. 12-16 (Ref. 121662). Within the group of large-scaled Marcusenius species, it can be distinguished from M. kutuensis and M. ghesquierei by a lower number of dorsal-fin rays, 22-25 vs. 27--31 and 32-34, and by a dorsal-fin length that is smaller than the anal-fin length, 64.5-92.2% of anal-fin length vs. larger than the anal-fin length; it differs from M. ghesquierei, M. intermedius, M. kutuensis and M. moorii by a higher number of lateral line scales, 46-53 vs. 36-45, and from M. fuscus by a lower number of lateral line scales, 46-53 vs. 54-61; it differs from M. dundoensis by a dorsal fin height which is smaller than the dorsal fin length, 70.8-96.0% of dorsal-fin length vs. both fins about the same length, and by a lower number of lateral line scales, 46-53 vs. 51-61, and a lower number of scales between dorsal and anal fin, 19-22 vs. 21-25; it can be distinguished from M. schilthuisiae by a lower number of anal-fin rays, 27-31 vs. 32-35; it differs from M. kaninginii and M. sanagaensis by its lower caudal peduncle depth, 4.4-5.9% of standard length vs. respectively 6.8-7.7% and 6.1-6.3%, which is also an additional difference to distinguish it from M. intermedius and M. moorii; it differs from M. kaninginii by a higher number of scales between dorsal and anal fin, 19-22 vs. 16-19, and between dorsal fin and lateral line, 9-11 vs. 6-9; and from M. sanagaensis by its lower number of dorsal-fin rays, 22-25 vs. 24-28, a lower number of scales between dorsal and anal fin, 19-22 vs. 22-28, between dorsal fin and lateral line, 9-11 vs. 11-14, and between pelvic fin and lateral line, 9-12 vs. 12-14 (Ref. 121662).

ຊີວະສາດ     ຄຳແປສັບ (ຕ.ຢ. epibenthic)

Found in the freshwaters near Banana up to Kindonda village, and in some smaller coastal rivers of the Democratic Republic of the Congo (Ref. 121662).
