[Dactylogyrids from the Siberian loach Nemachilus barbatulus toni in Primor'e region].

Two species of dactylogyrids, Dactylogyrus barbatuli Ermolenko, 1992 and D. tonii Ermolenko, 1992, occurring in the Siberian stone-loah in Primorye are redescribed. These species are distinguished from others monogenean of the genus Dactylogyrus, that are found in fishes of the genus Nemachilus, by the size of anchor structures and complexes of copulatory organs.
