RESUMO

In this study conducted a revision of the species composition of centric diatoms in the plankton of Lake Teletskoye, a deep oligotrophic reservoir in Altai Mountains (Russia). A total of 27 taxa of Centrophyceae from the genera Aulacoseira Thwaites, Conticribra K.Stachura-Suchoples & D.M.Williams, Cyclotella (F.T.Kützing) A. de Brébisson, Discostella Houk & Klee, Ellerbeckia Guide, Handmannia M.Peragallo in Handmann, Melosira C.A. Agardh, Orthoseira G.H.K. Thwaites, Pantocsekiella E.Acs, Rhizosolenia T. Brightwell, Stephanocostis Genkal et Kuzmin, Stephanodiscus Ehrenb., Thalassiosira P.T. Cleve are detected. The systematic position of the majority of earlier identified diatoms is specified. Twelve taxa, new to the flora of the lake, from 7 genera are recorded, including the species Pantocsekiella teletskoyensis Genkal et Mitrofanova sp. nov., which is new to science. The distribution of diatom species in the lake is determined, with three species - P. teletskoyensis, Aulacoseira subarctica (O.Müller) Haworth and Stephano-discus alpinus Hustedt emend. Genkal et Lepskaya - found at almost all sampling stations.
