Uma nova espécie de cestóide proteocefalídeo, Monticellia belavistensis, sp.n., parasita de Pterodoras granulosus (Valenciennes) (Pisces, Doradidae), do reservatório de Itaipu e rio Paraná, Paraná, Brasil

A New species of proteocephalidean cestode, Monticellia belavistensis, sp.n., parasite of Pterodoras granulosus (Valenciennes) (Pisces, Doradidae) from Itaipu reservoir and Paraná river, Paraná, Brazil

Resumo

In the present paper the authors describe and illustrate a new species of proteocephalidean cestode, Monticellia belavistensis, sp.n., parasite of a freshwater siluriform fish (thorny catfish). Pterodoras granulosus (Valenciennes, 1833), from the Itaipu Reservoir and Paraná River, in the region of Porto Rico. This is the first reference of a proteocephalid in this host. The values of prevalence and mean intensity of infection are given and the life cycle is discussed.
