[Thelohanellus njinei sp nov and T lagdoensis sp nov, Myxosporidia (Myxozoa: Myxosporea) parasites of Schilbeidae and Citharinidae fishes in Cameroon (central Africa)]

The study of Myxosporidia infecting Schilbe mystus (Linné, 1758) (Schilbeidae) and Citharinus citharus (Geoffroy Saint-Hilaire, 1809) (Citharinidae) from the Sanaga and Bénoué basins revealed the presence of two new species of the genus Thelohanellus kudo, 1993. These species are Thelohanellus njinei sp. nov. and Thelohanellus lagdoensis sp. nov., found in the gut of Schilbe mystus and Citharinus citharus respectively. New data are also given on the diagnosis of Thelohanellus citharini, a species previously described in Chad.
