Digenean Metacercaria (trematoda, Digenea, Lepocreadiidae) Parasitizing “coelenterates” (cnidaria, Scyphozoa and Ctenophora) from Southeastern Brazil

Metacercaria specimens of the genus Opechona (Trematoda: Digenea: Lepocreadiidae) are described parasitizing “coelenterates” (scyphomedusae and ctenophores) from Southeastern Brazil (São Paulo state). The worms are compared to other Opechona species occurring on the Brazilian coast, but no association has been made because only adult forms of these species have been described. Suppositions as t...

Hirudinella Ventricosa (trematoda) Parasitizing Makaira Nigricans and Acanthocybium Solandri from Neotropical Region, Brazil Hirudinella Ventricosa (trematoda) Parasitando Makaira Nigricans Y Acanthocybium Solandri De La Región Neotropical, Brasil

In January 2002, were caught 11 Makaira nigricans Lacepède, 1802 (Istiophoridae) and two Acanthocybium solandri (Cuvier, 1832) (Scombridae) off Cabo Frio municipality, Rio de Janeiro State, Brazil. We collected digenetic trematodes from the stomach of some of these fishes. We studied these trematodes with optical and scanning electron microscopy and identified them as Hirudinella ventricosa (Pa...
