Abstract
We report sporocysts and cercariae from 2 species of limpets (Siphonaria lessoni (n 5 500) and Kerguelenella lateralis (n 5 100)) and a metacercaria from S. lessoni, as well as an isopod (Exosphaeroma sp. (n 5 100)), all collected from the intertidal zone of the Argentinean Sea near Comodoro Rivadavia, Rada Tilly, and Punta Maqueda, Argentina. We assigned the limpet digeneans to Microphallidae, Schistosomatidae, and Hemiuroidea and provide a description of the metacercaria. We experimentally infected isopods with the microphallid cercaria for correlating this cercaria with metacercariae found in naturally infected isopods. Information regarding seasonal variation in prevalence is also provided.
