Abstract

In Africa, about a hundred species of Myxosporea are known to infest fishes in various countries. Species of nine genera have been described in freshwater fishes: Myxidium, Sphaerospora, Myxobilatus, Myxobolus, Thelohanellus, Unicauda, Henneguya, Chloromyxum and Kudoa. In the present note, we propose a key to the species infecting freshwater fishes. A systematic revision of some species is given. A list of different species, their hosts and their geographical distribution are also presented.
