N2 - During the parasitological investigations of african freshwater fishes in National park Nikolo Koba, Senegal, West Africa, altogether 5 species of viviparous monogeneans belonging to genus Macrogydactylus being found on the gills, fins and body surface of two species of host fish Clarias anguillaris and Polypterus senegalus (Clariidae and Polypteridae). The haptoral sclerites of specimens of the genus Macrogyrodactylus (fixed in mixture of glycerine and ammonium-picrate) were compared to the all described macrogyrodactylus species. On Clarias anguillaris, Macrogyrodactylus congolensis and Macrogyrodactylus karibae were found. In the case of Polypterus senegalus, the presence of three macrogyrodactylus species was recorded. One species have been recognized as Macrogyrodactylus polypteri and another two have been identified as Macrogyrodactylus sp.1 and Macrogyrodactylus sp.2. As a result of detail mopho-metrical analysis of structures of taxonomical importace, Macrogyrodactylus sp. 1 and Macrogyrodactylus sp. 2 can be recognized like a smallest ones in relation to all macrogyrodactylid species described till now. Macrogyrodactylus sp. 1 can be discriminated from Macrogyrodactylus sp. 2 almost exclusively by the shape of its hamuli and its ventral bar. At Macrogyrodactylus sp.1 the shape of marginal hooks on anterolateral lobes differs significantly from the shape of marginal hooks placed along posterior margin of the haptor. This finding provide good basis for decsription of two new species of genus Macrogyrodactylus. Moreover, occurence of five macrogyrodactylids species parasitic two species of fish living in National park Nikolo Koba represent also first record of this monogenean parasites in Senegal.
