Neotropical Monogenoidea. 56. New species of Anacanthorus (Dactylogyridae) from the gills of matrinchã, Brycon orthotaenia (Characiformes: Characidae), in the Rio São Francisco, Brazil.
The gills of the matrinchã, Brycon orthotaenia Günther, from the Rio São Francisco in Brazil are described from the gills and Anacanthorus brevicirrus resembles A. franciscanus, A. kruidenieri and A. elegans but is differentiated from these species by its short straight male copulatory organ.

Myxobolus franciscoi sp. nov. (Myxozoa: Myxosporea: Myxobolidae), a parasite of Prochilodus argenteus (Actinopterygii: Prochilodontidae) from the Upper São Francisco River, Brazil, with a revision of
Thorough comparisons with the remaining species of Myxobolus Butschli, 1882 described from South American fish, as well as with almost all species of Herbarium described so far, are provided. Expand
Neotropical Monogenoidea. 55. Dactylogyrids parasitising the pintado-amarelo Pimelodus maculatus Lacépède (Actinopterygii: Pimelodidae) from the Rio São Francisco, Brazil
Eight species of Dactylogyridae were collected from the gills of the pintado-amarelo Pimelodus maculatus Lacépède in the Rio São Francisco in Brazil: Ameloblastella paranaensis (França, Isaac,Expand
Ecological and reproductive aspects of Neoechinorhynchus pimelodi Brasil-Sato & Pavanelli (Eoacanthocephala, Neoechinorhynchidae) of Pimelodus maculatus Lacépède (Siluroidei, Pimelodidae) of the São
Recruitment and constant losses of N. pimelodi seem to be controlled by transmission mechanisms independently of density, and mechanisms may consist of infected prey availability and changes of preferred alimentary items in the diets of juvenile and mature P. maculatus. Expand
Neoechinorhynchus pimelodi sp.n. (Eoacanthocephala, Neoechinorhynchidae) parasitizing Pimelodus maculatus Lacépède, "mandi-amarelo" (Siluroidei, Pimelodidae) from the basin of the São Francisco
Neoechinorhynchus pimelodi sp.n. is described as the first record of Acanthocephala in Pimelodus maculatus Lacepede. 1803, collected in the Sao Francisco river, Tres Marias, Minas Gerais. The newExpand
Digenea of Hoplias intermedius and Hoplias malabaricus (Actinopterygii, Erythrinidae) from upper São Francisco River, Brazil.
The presence of metacercariae and adult digeneans indicate that they act as intermediate and definitive hosts, respectively, in their biological cycles, as a result of piscivorous feeding habits of these adult erythrinids from the upper São Francisco River. Expand
Ecological parameters of the endohelminths in relation to size and sex of Prochilodus argenteus (Actinopterygii: Prochilodontidae) from the Upper São Francisco River, Minas Gerais, Brazil
This research aimed to investigate the ecological indexes of the helminths of the digestive system and coelom of Prochilodus argenteus Spix & Agassiz, 1829. A total of 150 specimens (53 males and 97Expand
New species and reports of dactylogyrids (Monogenoidea) from Salminus franciscanus (Actinopterygii: Bryconidae) from the upper São Francisco River, Brazil.
Six species of dactylogyrid monogenoideans were collected at the upper São Francisco River, State of Minas Gerais, Brazil, from the gills of Salminus franciscanus, a new host record and a new locality record for Anacanthorus daulometrus, Annulotrematoides glossophallus, Jainus iocensis and Tereancistrum arcuatus.

Nematodes of Astyanax fasciatus (Actinopterygii: Characidae) and their parasitic indices in the São Francisco river, Brazil.
This fish acts as an intermediate host of some species of larval nematodes especially, Anisakidae and Acanthocheilidae (Brevimulticaecum sp., new host record and new locality) and acts as a definitive host for P. saofranciscencis and S. rodolphiheringi in the upper São Francisco river. Expand
A new species of Anacanthoroides and redescription of Apedunculata discoidea (Monogenoidea) parasitizing Prochilodus argenteus (Actinopterygii) from the São Francisco River, Brazil.
Anacanthoroides sanctifrancisci n. sp. from the gills of 'curimatã-pacú', Prochilodus argenteus from the São Francisco River, Brazil, is described and illustrated. Anacanthoroides, monotypic, isExpand
