A new Macrogyrodactylus (Monogenea, Gyrodactylidae) parasite of Heterobranchus longifilis Valenciennes, 1840 (Teleostei, Siluriforme) from Ivory Coast

A new species of Gyrodactylidae (Monogenea), Macrogyrodactylus heterobranchii n.sp. is described for the first time on a siluriform catfish of the genus Heterobranchus : H. longifilis Valenciennes, 1840 (Teleostei) in Ivory Coast (West Africa). This species can be distinguished from the other species of the genus (M. clarii and M. congolensis ) by the size of sclerotized parts of the haptor and the number of spines of the genital bulb (8-10).
