Daughter sporocysts and cystophorous cercariae were found in the gastropod Cylichna alba (Heterobranchia: Cephalaspidea) from the White Sea. By evidence from the rDNA sequences (partial 28S and 5.8S+ITS2) they match sexual adults identified as Hemiurus levinseni (Digenea: Hemiuroidea: Hemiuridae). We propose an outline of H. levinseni life cycle, describe morphology of its sporocysts and cercariae, and compare the latter with cercariae of other hemiuroideans. The position of the genus Hemiurus w
