The paper is a continuation of a series of publications devoted to diatoms of the city of Kiev. It presents data on species diversity of araphid genera from families Fragilariaceae, Diatomaceae, and Tabellariaceae studied by TEM and light microscopy. In literature, 24 species (27 infraspecific taxa) of fragillarian diatoms from 10 genera are cited for small water bodies of Kiev. Our study revealed 38 species (39 infraspecific taxa) from 13 genera of araphid diatoms including three taxa, which were not identified on the species level. Opephora guenter-grasii (Witkowski et Lange-Bert.) Sabbe et Vyverman, P. polonica (Witak et Lange-Bert.) Morales et Edlund, and Punctistriata glubokoensis D.M. Williams et al. are first records for Ukraine. Two species are new records for the Forest zone of Ukraine, and one variety is new for the Forest-Steppe zone of Ukraine. One species, Pseudostaurosira ovalis sp. n., was described as new for science. Meridion ovatum typification on original material was done for this rare and dubious species. In the floristic spectrum no genera are distinctly dominant: the number of species decreases gradually by one. Genus Fragilaria Lyngb. ranks first (6 species or 16.7%) followed by Ulnaria and Pseudostaurosira (5 species or 13.5% each). The most common species in small water bodies of Kiev were cosmopolitan representatives of genera Ulnaria and Fragilaria. According to the generalized literary and original data, 43 species from 14 genera of araphid Bacillariophyta were found in small reservoirs of Kiev. Their descriptions, localities, and distribution are given.
