Resumo: A new species of Cladorchiidae (Trematoda, Digenea) was found in the intestinal tract of freshwater fish “pacu peva”, Metynnis maculates (Kner, 1858) from the Upper Paraná 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.

A nova espécie foi classificada no gênero Dadayius Fukui, 1929 por apresentar testículos não lobados e acetábulo ventro-terminal com um “entalhe” postero-mediano na margem interior, características do gênero que possui apenas duas espécies conhecidas. Algumas características que diferem a espécie nova de D. marenzelleri (Daday, 1907) e D. pacuensis Thatcher, 1996 são cecos não alcançando o acetábulo, vitelária de extensão limitada e não atingindo o nível do testículo posterior e a presença de dois tamanhos diferentes de ovos em dois estágios de maturação diferentes.Universidade Estadual De Maringá2008-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/204410.4025/actascibiolsci.v25i2.2044Acta Scientiarum.
