RESUMO

The rare species Carteria abiscoensis Skuja previously known only from Swedish Lapland was found in the water bodies of Ukraine. Study of morphological diversity of three populations of this species (two from the Carpathian Biosphere Reserve and one from the Goloseevo pond in Kiev) revealed at times continual and sometimes discrete variability of some morphological characters (shape, dimensions and location of stigma and pyrenoid, depth and width of the anterior excision of chloroptast, thickness of the cell wall, dimensions of cells). This variability shows up both on the intra- and interpopulational levels. Taxonomic interpretation of variability revealed is proposed: two new for science infraspecies taxa, C. abiscoensis var. kyivensis Massjuk et Lilits. var. nov. and C. abiscoensis var. abiscoensis f. carpatica Massjuk et Lilits. f nov. are described. The descriptions, Latin diagnoses and original drawings are given.
