Abstract

Two rare species of diatom algae, Chamaepinnularia circumborealis and Neidiopsis wulffii, are recorded in water courses and waterbodies in the Yamal Peninsula (Western Siberia, 69°16′2.8″–70°33′53.6″ N, 68°04′10.3″–68°9′57.46″ E). New data on their ecology and distribution are provided. A SEM study of these species has shown their broader variability in diagnostic characters (valve length and width, number of striae in 10 μm, shape of valve, raphe and central area, structure of striae) in comparison with published data. Descriptions of Chamaepinnularia circumborealis and Neidiopsis wulffii are refined. Their differentiation from morphologically similar species is discussed.
