The precise location of sensillae of the cercaria of E. trivolvis is described. This study allows one to distinguish E. trivolvis from E. revolutum, E. echinatum, E. caproni, E. jurini and E. parvocirrus on the basis of the arrangement of the argentophilic structures of their cercariae. She arrangement of the tegumentary receptors of the circle AI dorsal (AID) complex allows for clear differentiation of the cercariae of E. trivolvis from the cercariae of all trematode species studied by silver nitrate staining in the genera Echinoparyphium, Hypoderaeum, Moliniella, and Paryphostomum in the family Echinostomatidae.
