Etymology: Marcusenius: Becasue of J. Marcusen, author of "Zur Phauna des Schwarzen Meeres", 1867; ichthyologist; wamuinii: This species is dedicated to Professor Soleil Wamuini Lunkayilakio of the Institut Supérieur Pédagogique de Mbanza-Ngungu, to acknowledge his great contribution to the sampling effort in the area, which resulted in the discovery of the new species, and to recognize him as one of the first Congolese ichthyologists (Ref. 121662).
Eponymy: Dr Johann Andreas Marcusen (1817–1894) was a Latvian of German descent who was a physician, ichthyologist and zoologist. [...] Professor Soleil Wamuini Lunkayilakio is an ichthyologist who is a research scientist at the Institut Supérieur Pédagogique de Mbanza-Ngungu, DRC, and associated with the University of Liège.

Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 22 - 25; Épines anales: 0; Rayons mous anaux: 27 - 31. 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).
Body shape (shape guide): fusiform / normal.
Body shape (shape guide): fusiform / normal.
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).
