During a survey of parasites of the Patagonian freshwater crab Aegla neuquensis neuquensis, its ectosymbiotic Temnocephala chilensis was found parasitized with an echinostomatid metacercaria with 43 collar spines. Of the 414 T. chilensis collected, 106 were parasitized with metacercariae of Echinoparyphium sp. Ovigerous adults of E. megacirrus were obtained from domestic chicks experimentally infected with metacercariae obtained from temnocephalans being parasitized by digeneans.
