| Abstract | A new species of Cladorchiidae (Trematoda, Digenea) was found in the intestinal tract of freshwater fish "pacu peva", Metynnis maculatus (Kner, 1858) from the Upper Parana River floodplain, southern Brazil. The new species was classified in the genus Dadayius Fukui, 1929 by having non-lobate testis and a ventro-terminal acetabulum with postero median notch on rim, characters of the genus wich has only two previously known species. Some characters that differ the new species from D. marenzelleri (Daday, 1907) and D. pacuensis Thatcher, 1996 are: ceca not reaching acetabulum, vitellaria of limited extension, not reaching the level of posterior testis and the presence of two different egg sizes in two different maturity stages. |
