Morphological measurements of Gyrodactylus magadiensis n. sp. from the Magadi tilapia, Alcolapia grahami collected from Lake Magadi, Kenya. Data are presented alongside data for the only other previously described Gyrodactylus species from Kenya. Data compiled from previous study directly transposed as noted by author.
