The literature and new field data on the taxonomic composition of benthic invertebrates (macrozoobenthos and zooperiphyton) from the River Biya and its tributaries are provided. The study area is located in the northeast of Altai, at altitudes of 160-1700 m asl (N 51°30'-52°70', E 85°03'-87°27'). The paper presents 198 species (Cnidaria, Plathelminthes, Annelida, Mollusca and Arthropoda), including 87 previously not recorded for the study area.
