This species is distributed in the Central Zaire basin, where it is found in three different localities far from each other. See Boden et al. (1997)
Marcusenius intermedius is known from the type locality Kabambaie on the Kasa River, from Komi, Lodja and from Koteli, all in the Central Congo River basin.

From Boden et al. (1997)
Diagnosis. Mouth subinferior rather than terminal as in the other species. Dorsal-fin origin behind anal-fin origin. Dorsal-fin base ends before anal fin. Dorsal-fin margin rounded anteriorally and slightly concave, its height about the same length as its base. Dark transverse band between dorsal and anal fin, not always clearly visible, covered with three lateral-line scales. Lateral-line scales 38-43. Short dorsal and anal fin, with 21-22 and 28 rays respectively.
Description. Mouth subinferior. Teeth bicuspid, five in upper jaw, six in lower jaw. Sub-mental swelling small and hardly visible, probably damaged in the three available specimens, with posterior end terminating well under the middle of the eye. Snout pointed slightly. Anterior nostril a little closer to the eye than to the anterior tip of the snout. Posterior nostril at 0·2-0·25 distance between snout and anterior eye border. Eye diameter 45-49% of snout length. Preanal distance a little shorter than predorsal distance. Dorsal fin shorter than anal fin. Dorsal-fin height about the same as its base, but anal-fin height shorter than its base. Pectoral fin twice as long as pelvic fin and reaching the pelvic-fin base. Pelvic-fin base at about 0-4 of the distance between pectoral-fin base and anal-fin origin. Its length is a little shorter than half the distance between its basis and the anal-fin origin. Low number of dorsal- (21-22) and anal- (28) fin rays. Lateral-line scales 38-43. Transversal dark band between origin of dorsal and anal fins covered with three lateral-line scales. Seventeen to 18 transversal scales between dorsal and anal fins. Caudal peduncle height is about half its length. Caudal peduncle, head, and transversal dark band are darker than the rest of the body. Low number of vertebrae (42-43).
Comment. The systematic status of this species is questionable. Moreover, only three specimens are presently available for study. More material is necessary to obtain a correct idea on the status of this species. Meanwhile we continue to consider it as a valid taxon.
