Abstract

Distome cercariae were found to emerge from naturally infected Melania tuberculata and Vivip < /span>ara unicolor snails in Assiut city. Cercariae develop in sporocysts. Mixed infection with cercaria of Haplorchis pumilio was noticed in Melania tuberculata sna il. The cercaria and sporocysts were fully described and compared form previously reported ones. By anology of adult and metacercarial stages of trematodes recorded in Assiut city, it was suggested that the present cercaria might be the larval stage of Eumegacetes (Eumegacetes) spinosus Fahmy, Khalifa and Abdel-Rahman, 1981.
