RESUMO:

With the aim of studying the diversity and the host-parasite association of Anacanthorus
spp. parasitizing fish of the family Serrasalmidae, between October 2015 to July 2016
parasitological surveys of 11 species of serrasalmids, from 4 different localities, the
Miranda River (State of Mato Grosso do Sul), the Mogi Guaçu River (State of São
Paulo), the Upper Paraná River (State of Paraná) and the Xingu River (State of Pará).
Hosts were analyzed immediately after capture to verify the presence of parasites.
Parasites were analyzed morphologically through light microscopy, and some species
were sequenced genetically. The phylogenetic position of the species of Anacanthorus
parasites of serrasalmids fish was investigated based on partial sequences of the 28S
gene of 9 species of Anacanthorus, a new sequence of the species Mymarothecium
viatorum, and 39 monogenean sequences retrieved from GenBank. The analyses
support the monophyly of the anacanthorine, represented by Anacanthorus in this study,
and the phylogenetic relationships between Anacanthorus spp. corresponded to the
phylogenetic relationships among the three major lineages of Serrasalmidae (“pacus”,
“Myleus-like pacus” and “true piranhas”). Two new species of Anacanthorus were
found and described, the first from the gills of Serrasalmus maculatus, and the second
from the gills of Myloplus schomburgkii, both differing from its congeners mainly by
the morphology of the copulatory complex. Additionally, new hosts and geographical
records were provided, together with new partial sequences of the mitochondrial
cytochrome c oxidase subunit 1 gene (COI) of species of Anacanthorus.
