Juvenile didymozoids of the types, Torticaecum and Neotorticaecum (Didymozoidae: Digenea), from new marine fish hosts (Pisces: Teleostei) in the neotropical region of Brazil.
From December 2006 to March 2008, 60 specimens of Paralichthys isosceles and 25 specimens of P. patagonicus were investigated for helminths. One hundred and sixty-nine digeneans were recovered and parasites were identified as juvenile didymozoids of two types. Torticaecum and Neotorticaecum were found in 48 of the 60 P. isosceles (80%) and 10 of the 25 P. patagonicus (40%). Torticaecum and Neotorticaecum are reported for the first time in fish in South America (Brazil), found in the Atlantic Ocean. Morphometrics and illustrations are presented.
