Marcusenius cuangoanus is only known from a restricted area in the Kwango basin and is threatened by artisanal, but very intensively diamond mining. It is unsure whether the known distribution is its true distribution or whether it is the result of low sampling intensity. It is expected to be more widespread in the Kwango River basin though. Therefore, the species is listed as Vulnerable, assuming that the number of locations is fewer than 10 and that the AOO is less than 2,000 km.

Threats:
Major Threats
Artisanal, but very intensively diamond mining is a very important threat in small rivers in the Kasai region. The sand from digging in the river and the river beds causes sedimentation.
