PROPAPPIDAE AND AQUATIC ENCHYTRAEIDAE (OLIGOCHAETA) FROM THE FARTHESTSOUTHEAST OF RUSSIA

Two mountain streams north and northeast of Vladivostok were studied i n 1983-1984. In the Komarovka Stream, a great variety of Mesenchytraeu s occurred in the spring zone, among them M. crenobius sp. n. with gia nt setae in the ventral bundles of VI-VIII and M. vshivkovae sp. n. wi th numerous spermathecal diverticula. In the stream zone of the Frolov ka Stream Cernosvitoviella pensau sp. n., characterized by a complicat ed penial bulb and a very long spermathecal ampulla, was the dominant oligochaete. Propappus arhynchotus Sokolskaya was the second most abun dant oligochaete in this stream. It proved to be a true member of this genus and not synonymous with any other species. These are the first records of aquatic enchytraeids for the Primorski Region of Russia.
