Data are presented on the life- cycles and the postembryonal development of four species of Branchiopodataenia Bondarenko & Kontrimavichus, 2004, B. anaticapicirra Bondarenko & Kontrimavichus, 2004, B. arctowskii ( Jarecka & Ostas, 1984), B. haldemani ( Schiller, 1951) and B. pacifica ( Spassky & Jurpalova, 1968), which are specific parasites of gulls. The investigation was carried out in Chukotka ( Chaun Bay) between 1971 and 1981 under natural and experimental conditions. Branchiopod crustaceans were exclusive natural and experimental intermediate hosts of all of the species studied; this fact provided additional evidence for the erection of Branchiopodataenia. The metacestodes exhibit a pattern of postembryonal development and a typical larval form, termed a ' cercocyst', which is a modification of a cysticercoid. This modification of the metacestode does not occur in species of Wardium Mayhew, 1925, the genus with which species of Branchiopodataenia had previously bee!.
