“…The first reference to this kind of hyperparasite infestation was by Riggenbach (1896) in a scolex of Corallobothrium lobosum in Luciopimelodus pati. Recently, Rego & Gibson (1989) reported several cases of hyperparasitism of proteocephalideans occuring in pimelodid fishes, by as yet undetermined species of proteocephalideans.…”

Mariauxiella pimelodi n. g., n. sp. (Cestoda, Monticelliidae, Othinoscolecinae) is described from the South American siluriform fishes Pimelodus ornatus and Pimelodus sp. caught in Brazil and Paraguay. When compared with other genera of South American monticelliids, the new genus exhibits the following morpho-anatomical characters: the particular development of the distal circular musculature of the suckers acting as a sphincter; the medullar ovary projecting numerous lobules into the dorsal cortex; and the uterus situated in the ventral cortex but with numerous outgrowths penetrating the medulla and reaching the dorsal cortex in pregravid proglottids. The new species is the fourth monticelliid cestode recorded from Pimelodus. ResumoMariauxiella pimelodi n. g., n. sp. (Cestoda, Monticelliidae, Othinoscolecinae) 6 descrita do peixe siluriforme Pimelodus ornatus e Pimelodus sp, colectados no rio Cuiabzi em Mato Grosso e no rio Parami, Paran~, Brasil e no rio Pirapo, em Caazapa, Paraguay. Este genero se diferencia dos outros g~neros descritos de Monticelideos pelos seguintes caracteres, mais importantes: a musculatura especial das ventosas, lembrando esfincter, mas de morfologia diferente; o ovario medular, mas projetando foliculos no cortex dorsal; o utero, localizado no cortex ventral, mas seus diverticulos projetam pequenas h6rnias, que atravessam a medula e atingem o cortex dorsal. Esta 6 aquarta especie descrita de hospedeiro do genero Pimelodus.

“…None ofthese reports showed whether these larvae were obligate transmission stages, or, if infected fishes were facultative paratenic hosts. REGO & GIBSON (1989) found hyperparasitism of adult by larval proteocephalids. Jauella glandicephalus, Megalhylacus brooksi, Peltidocotyle rugosa and Travassiel/a avitellina from the intestines of Paulicea luelkeni, Choanoscolex abscissus from Pseudoplatystoma corruscans, an unidentified proteocephalid from Pseudoplatystomafascialus, Proteocephalus sp.…”

Keys to genera of cestodes in South American freshwater teleost fishes are provided, with diagnoses of genera and short descriptions of species. Two new genera are proposed, Chambriella gen.n. for Goezeella agostinhoi Pavanelli & Santos, 1992 and G paranaensis Pavanelli & Rego, 1989, and Brooksiella gen.n. for Amphoteromorphus praeputialis Rego, Santos & Silva, 1974. Nomimoscolex magna Rego, Santos & Silva, 1974, previously species inquirenda, is transferred to the genus Proteocephalus Weinland, 1858. Goezeella nupeliensis Pavanelli & Rego, 1989 is considered a species inquirenda. Species and host lists are included

The parasite fauna of catfish, Pimelodus pohli, from the São Francisco River Basin is presented. A total of 45 catfish from the upper São Francisco River (45°15'44"W 18°13'25"S), were examined from July 2009 to September 2011. Forty-three catfish (95.5%) were infected by at least one parasite species, with 885 parasite specimens being found, distributed across 17 species: Monogenea (Demidospermus uncusvalidus, Pavanelliella pavanellii, and Scleroductus sp.); Eucestoda (plerocercoids of Proteocephalidea); Digenea (metacercariae of Austrodiplostomum compactum, adults of Auriculostoma platense and Kalipharynx sp., and juvenile of Prosthenhystera obesa); Nematoda (larvae of Contracaecum sp., Hysterothylacium sp., Procamallanus pimelodus, Procamallanus sp., and unidentified of Cucullanidae, and adults of Cucullanus caballeroi, Philometra sp., and Procamallanus freitasi); and Acanthocephala (adults of Neoechinorhynchus pimelodi). Procamallanus freitasi and Scleroductus sp. were the taxa with the highest prevalence. Demidospermus uncusvalidus, P. freitasi, and Scleroductus sp. were the dominant species. The host's sex did not influence parasitic indexes; however, the total length of the catfish did appear to have some influence. The parasites, with except for P. obesa, were registered for the first time in P. pohli, as well as the occurrence of Kalipharynx sp. and C. caballeroi among pimelodid hosts from São Francisco River and South America.
