Etymology: Marcusenius: Becasue of J. Marcusen, author of "Zur Phauna des Schwarzen Meeres", 1867; ichthyologist; verheyenorum: This species is dedicated to the late Professor Emeritus of the University of Antwerp, Walter Verheyen, and his son Eric Verheyen of the University of Antwerp and the Royal Belgian Institute of Natural Sciences; both are zoologists who in particular have been contributing to our knowledge of the vertebrate fauna of the Congo basin; the species is dedicated to both in deep recognition of their commitment to the training of Congolese researchers in general and those of the University of Kisangani (UNIKIS) and the Centre de Surveillance de la Biodiversité (CSB) in particular (Ref. 124516).
Eponymy: Dr Johann Andreas Marcusen (1817–1894) was a Latvian of German descent who was a physician, ichthyologist and zoologist. [...] Professor Dr Walter Norbert Verheyen (1932–2005), father of Dr Erik K Verheyen (above), was a Belgian zoologist who was (1966) a professor at the Biology Department of the University of Antwerp, having previously (1962) been a lecturer at the [...] (Ref. 128868), visit book page.

Espinhos dorsais (total) : 0; Raios dorsais (total) : 20 - 21; Espinhos anais: 0; Raios anais : 26; Vértebras: 40 - 41. Diagnosis: Marcusenius verheyenorum belongs to the group of species of Marcusenius with eight large circumpeduncular scales (Ref. 124516). In this group, it differs from M. dundoensis, M. fuscus, M. lambouri, M. sanagaensis, M. schilthuisiae and M. wamuinii by its low number of lateral line scales, 38-43 vs. 51-56, 54-61, 45-48, 44-46, 43-54 and 46-53, respectively; it differs from M. ghesquierei and M. kutuensis by its low number of dorsal-fin rays, 21-22 vs. 32-34 and 27-31, respectively; it differs from M. intermedius, M. kaninginii, M. lambouri and M. moorii by its low total number of vertebrae, 40-41 vs. 42-43, 43-44, 44-45 and 42-44, respectively, and a deep caudal-peduncle height, 44.9-54.6% of its length vs. 37.8-43.8%, 35.0-43.0%, 29.8-39.3% and 29.4-41.3% respectively (Ref. 124516).
