Abstract
Eleven oligochaete taxa were found in the Edinka Stream, Primorskij Region, dominated by Cernosvitoviella pensau Timm, 1994 ; Propappus arhynchotus Sokolskaja, 1972 ; Rhyacodrilus komarovi Timm, 1990 ; and R. coccineus (Vejdovsky, 1875). The oligochaete fauna was similar in two well-separated reference streams, the Edinka and the Frolovka, but poor in comparison with a third stream, the Komarovka. Slight zoogeographical relations to the Kamcatka Peninsula are evident in the Edinka and Frolovka, both of which flow down the eastern slope of the Sihote-Alin Mountains.
