Abstract

Redescriptionof Brooksiella praeputialis and Goezeella siluri (Eucestoda:Proteocephalidea), parasites of Cetopsis coecutiens (Siluriformes) from the Amazon, and proposition of Goezeella danbrooksi sp.n. -Brooksiella praeputialis (Rego, Santos & Silva, 1974) and Goezeella siluri Fuhrmann, 1916 from the Amazonian siluriform fish Cetopsis coecutiens (Siluriformes: Cetopsidae) are redescribed.Goezeella piramutab Woodland, 1933 is considered as a synonym of Goezeella siluri.Goezeella siluri sensu Brooks & Rasmussen, 1984 becomes Goezeella danbrooksi sp.n., differing from G. siluri by the vitelline follicles position (only dorsal, not lateral), size (much smaller in type material) and shape (slightly wider posteriorly); by the position of vaginal sphincter (which is terminal in G. siluri) and by the number of
