Parasitological examination of Paramormyrops kingsleyae Günther, 1896 caught in the Djolon River in Cameroon revealed the presence of three new species of Myxosporidia of the genus Myxidium Bütschli 1882 and Henneguya Thelohan, 1892 of which complete description is given in the present study. These species are: Myxidium binguelai sp. nov., parasite of the kidney that produce fusiform spores with a turgid medial part and both ends pointed. They measured 12.1 (11.1-12.9) μm long x 5.3 (4.8-5.8) μm broad; the polar capsules are ovoid, equal in size and measure 3.6 (3.0-4.1) μm x 2.5 (2.0-2.8) μm. Myxidium djolonensis sp. nov., a parasite of the gall bladder and urinary bladder, produce fusiform and elongated spores, that measure 16.3 (15.5-18.0) μm long x 6.1 (5-7.1) μm broad; its polar capsules are equal and measure 4.9 (4-5.6) x 3.5 (3-4.2) μm. Henneguya paramormyropsi sp. nov. form cyst in gill, eye and kidney. The total spore length is 29.2 (25.5-32.5) μm. The ovoid spore body, with narrowed anterior end measure 11.9 (10.7-12.8) μm x 4.5 (3.9-5.9) μm. The two separate caudal appendages measure 17.3 (14-20.3) μm. The 2 equal-sized thin and smooth valves surrounded 2 equal-sized pyriform, elongate polar capsules (5 (4.2-5.6) ×1.5 (1.2-1.9) μm) that contained 3 to 4 coils of the filament.
