Justification

The taxonomy of the southern Marcusenius is not fully resolved. Results from electric organ discharges and genetics to date give mixed results. This seems to indicate there is more than one species present in the southern systems, a possibility supported by morphological and ecological evidence. The range/s of the southern species needs to be determined before a meaningful assessment can be made.

Threats:

Major Threats

Upper catchments in Swaziland in particular are threatened by sedimentation caused by poor farming techniques and forestry operations. To the north in South Africa industrial pollution and forestry result in a mixture of chemical and sediment pollution.

Biology:

Occurs in fast-flowing, major, perennial rivers, bordered by dense subtropical or tropical vegetation and with high water conductivity. Usually found during the day below undercut river banks, especially in dense network of tree roots. Has been observed high up in river systems with rapid water flow and rocky substrate in Swaziland (Ref. 75962).
