The cercaria of N. kentuckiensis was found in Anaplocamus dilatatus (Nitrocris d.) and Mudalia carinata. The metacercaria was found in all fishes examined from Opequon River, West Virginia, except Cottus bairdi which was also refractory to experimental infection. Two species of Centrarchidae, four of Cyprinidae, three of Salmonidae, Etheostoma flabellare, Platypoecilus maculatus, and Trichogaster trichopterus were experimentally infected. The development of the metacercari and cyst and effect on the fish are described. The histopathology initially consists of hemorrhage and muscle necrosis about the metacercaria, followed by reorganization and formation of a loose connective tissue cyst. The controversial adult names are discussed and an emendation of the genus Neogogatea is presented.
