Despite the marked similarity in the ultrastructural pattern of the aspidogastrean and two digeneans studied, there is some degree of variation in the secretory activity of their uterine epithelium. The high level of vesicular exocytotic activity in the epithelial cytoplasm of A. lucii may be associated with differences in egg emission and the subsequent life cycle involving a non-ciliated, non-swimming and non-free-living miracidium, as opposed to the free-swimming miracidium of P. angulatum. The similar nature of the uterine epithelium in all three species studied represents an ultrastructural marker possibly supporting a close phylogenetic relationship between the Aspidogastrea and the Digenea.
