title: [About the fauna of the cestode family Hymenolepididae from ducks of Chukotka: on the validity of the genus Echinatrium].
abstract: Four species of the genus Echinatrium Spassky et Jurpalova, 1965 are redescribed. The material was collected from ducks of the Chaunskaya lowland (Chukotka). Morphological study of genital apparatus in cestode species found was carried out. According to the priority rule, it is suggested that the genus Monosaccanthes Czaplinski, 1967 is a junior synonym of the genus Echinatrium.
