There is a form of the "Marcusenius macroleptidotus group" that occurs in the Congo basin that was not treated in Kramer et al.'s recent revision of the group in southern Africa. As the southern forms are now divided into separate species, this Congo form is now "orphaned" pending its own systematic study.

Caught with dipnets in the Kafue floodplain, Zambia. Prefers well-vegetated, muddy bottomed marginal habitats of rivers and floodplains. A shoaling species which moves inshore after dark. Migrates within rivers. Recorded to move up tributaries in shoals during flood season (Ref. 13337). Feeds on invertebrates, especially midge and mayfly larvae and pupae taken from the bottom and off plant stems. Breeds during the rainy season in shallow vegetated localities; females carry up to 6,000 eggs (Ref. 7248). Possesses electroreceptors over the entire head and on the ventral and dorsal regions of the body, but absent from the side and the caudal peduncle where the electric organ is located (Ref. 10011).

This species is restricted to the Middle and Lower Zambezi system and the Buzi River to the south. It possibly also occurs in Lake Malawi, but the identity of these specimens needs to be re-examined.
