Research identifies five Dactylogyridae parasites in Brycon cephalus, suggesting host specificity.
During studies on parasites of fishes from Moa River, state of Acre, five species of Dactylogyridae were identified parasitizing Brycon cephalus (Günther, 1869): Anacanthorus elegans Kritsky, Thatcher & Kayton, 1979, Anacanthorus kruidenieri Kritsky, Thatcher & Kayton, 1979, Anacanthorus spiralocirrus Kritsky, Thatcher & Kayton, 1979, Annulotrematoides bryconi Cuglianna, Cordeiro & Luque, 2003, and Tereancistrum kerri Kritsky, Thatcher & Kayton, 1980. New morphological and biogeographic data are provided. Records of these parasites in congeneric hosts reinforce the host specificity of these species, restricted to species of Bryconidae.
