ABSTRACT: A new solitary entoproct species, Loxosomella angusta sp.n. is described. It is a medium-sized species (total length up to 0.575 µm) with a narrow calyx that bears 8 tentacles. A basal part of a stalk is thinner than the rest of a stalk and looks empty. The new species was found in the Kandalaksha Bay in the White Sea on the gymnolaemate bryozoan Electra sp. Bryozoans are one of the usual types of host animals for solitary entoprocts. A list of loxosomatids associated with bryozoans is given.
