Three new species of Goezia from fishes in North America are described and supplemental data for G. minuta and several unidentified adults and larvae are presented. Males, especially their caudal papillae, are necessary to identify most species. For the new species, G. pelagia sp. n. from Rachycentron canadum and Chaetodipterus faber in the northern Gulf of Mexico possesses 12- 19 preanal, two para-anal, and four postanal pairs of papillae; G. kliksi sp. n. from Pogonias cromis in Lake Borgne, Louisiana, has 10-16 preanal, two para-anal, and five postanal pairs of papillae, and G. sinamora sp. n. from Tilapia aurea, Micropterus salmoides, and Morone saxatilis in freshwater habitats in Florida possesses 13-16 preanal, two para-anal, and three postanal pairs of papillae. Records on several unidentified females without corresponding males and other assorted specimens are included to reveal a more complete understanding of hosts and localities for species of Goezia. Characteristics provided in a table distinguish the 18 nominal species parasitizing both fishes and aquatic reptiles throughout the world. We also provide observations on pathology, attachment, and life histories of selected species. Whereas most species of Goezia cause conspicuous lesions in fishes, few infected fishes are actually diseased. Also, those diseased fishes are often components of recently established host-parasite relationships.
