Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Actinopterygii Osteoglossiformes Mormyridae

Scientific Name: Marcusenius devosi Kramer, Skelton, van der Bank & Wink, 2007
Taxonomic Notes: Formerly considered to be M. macrolepidotus, but described as a new species in 2007. Other populations in East Africa remain to be critically assessed, including specimens from the Rovuma system, considered by Kramer et al. (2007) to be intermediate between M. devosi and M. macrolepidotus but closer to the former.

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2010
Date Assessed: 2010-02-10

Uncertainty over the identity of East African populations other than the Tana River means that the extent of occurrence is unknown, while the Tana River itself is extensively used for irrigation and power generation.

Geographic Range [top]

Range Description:This species is known from the Tana River system in Kenya (Seegers et al. 2003). Other populations in East Africa remain to be confirmed as populations of this species.

Population [top]

Population:Not known within Tana river. It may be widespread and common in other East African rivers (if they are confirmed as M. devosi).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It probably is found in similar habitats to Marcusenius macrolepidotus, i.e. marginal riverine vegetation.

Use and Trade [top]

Use and Trade: This species is harvested for human consumption.

Threats [top]

Major Threat(s): The Tana River is affected by hydroelectric generation and irrigation schemes. The potential impact of these on the species is unknown.

Conservation Actions [top]

Conservation Actions: None known. More research is needed into this species taxonomy, population numbers and range, biology and ecology, habitat status and threats, as well as monitoring and potential conservation measures.
