New material of the poorly known plectambonitoid brachiopod Ujukella fastigata (Rubel) is described from the Lower Ordovician (upper Volkhov) of Ingria, Russia. The closely related plectambonitoid brachiopods, U.? geometrica (Kutorga), from the Lower Ordovician of Ingria, Russia, U. sp. from the Lower Ordovician of Öland, Sweden, and U. alexandrae Andreev (= U. minima Andreev) from the Middle Ordovician of southern Siberia, Russia are redescribed in order to draw comparison with U. fastigata. These taxa are referred to the Family Leptesti-idae, based on a new cladistic analysis.
