A number of rare or unknown desmid species were revealed in samples collected from a range of aquatic habitats in Japan. In the present paper we describe one new species of the family Desmidiaceae, Staurastrum tsukubicum sp. nov. and report the presence in Japan of two species, Staurastrum levanderi Gronbl. and Cos?marium dilatatum Lutkem. in Jarnefelt et Gronblad, previously found only in Europe. One taxon, Euastrum englerii Schmidle var. madagascariense Bourr. et Manguin, is renamed as Euastrum biverrucosum nom. nov. et stat. nov. The morphology of these taxa was studied using light and scanning electron microscopy and their taxonomic affinities are discussed.
