 | An editor has marked this as a promising draft because the subject is notable per WP:NSPECIES, and requests that, should it go unedited for six months, G13 deletion be postponed, either by making a dummy edit to the page, or by improving it and submitting it for review.

Marcusenius devosi is a species of freshwater elephantfish in the family Mormyridae. It is endemic to eastern Africa, where it is known from the Tana River system in Kenya. Like other members of its family, it is a weakly electric fish that uses electric organ discharges for navigation and communication.[1]
Taxonomy
[edit]Marcusenius devosi was described in 2007 by Bernd Kramer, Paul Skelton, Herman van der Bank, and Michael Wink during a taxonomic revision of the Marcusenius macrolepidotus species complex. The study recognized several allopatrically distributed species that had previously been treated as a single widespread taxon.[2]
The species is currently placed in the genus Marcusenius, which comprises medium- to large-bodied mormyrids distributed throughout sub-Saharan Africa.
Etymology
[edit]The specific name devosi honors the Belgian ichthyologist Luc De Vos (1957–2003), former curator of fishes at the National Museums of Kenya, in recognition of his contributions to African ichthyology and his role in identifying the distinctiveness of this species.[1]
Description
[edit]Marcusenius devosi has an elongated, laterally compressed body typical of the genus. It possesses a protruding lower jaw with a fleshy chin appendage and a long dorsal fin positioned posteriorly on the body. As in other mormyrids, an electric organ located in the caudal peduncle produces weak electric signals used for electrolocation and communication.[2]
Diagnostic characters distinguishing M. devosi from related species include morphometric proportions, scale counts, fin-ray counts, and characteristics of its electric organ discharge, as described in the original species description.[2]
Distribution and habitat
[edit]The species is known from the Tana River basin in Kenya. It inhabits tropical freshwater river systems and is demersal, occurring near the bottom of rivers. Its full distribution outside the Tana system remains poorly documented.[2]
Ecology and behavior
[edit]Like other members of the family Mormyridae, Marcusenius devosi is presumed to be nocturnal and to rely heavily on electrolocation when foraging in turbid water.[2]
