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. The arrangement of the tegumentary receptors of the circle Al 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.
Résumé
La localisation précise des papilles tégumentaires de cercaires d'E. trivolvis est décrite. Les études permettent de distinguer E. trivolvis de E. revolutum, E. echinatum, E. caproni, E. jurini et E. parvocirrus selon la disposition des papilles sensorielles de leurs cercaires. La disposition des récepteurs tégumentaires du complex AID permet une claire différenciation des cercaires d'E. trivolvis de celles de toutes les espèces de trématodes du genre Echinoparyphium, Hypoderaeum, Moliniella, et Paryphostomum de la famille des Echinostomatidae, étudiées par coloration au nitrate d'argent.
