This paper summarizes the results of original research and analysis of published data on species composition of planktonic and benthic diatoms from the coastal waters of Sevastopol and Sevastopol Bay. During monthly environmental monitoring, conducted in 2009−2014 by the Department of Biophysical Ecology, IBSS NAS of Ukraine, in Sevastopol coastal waters, 48 Bacillariophyta species were identified. They belonged to 31 genera, 23 families, 18 orders, and 3 classes. Among them, approximately 10 species dominated in number varying from season to season. However, the diatoms' maximum abundance in 2008−2014 was significantly lower than in previous periods. The analysis of published data covered the period from 1903 to 2014. In the bibliography, a total of 379 diatom species and sub-species (infraspecific taxa) were mentioned. We compiled their list and revised it according to modern taxonomy. As result, for the period of 111 years of observations, the most comprehensive inventory of diatoms from the coastal waters of Sevastopol and Sevastopol Bay was produced. This inventory contains indications of reliability of species with historical and recent findings, which is valuable information for improving routine monitoring and species identification. The species list includes 334 species (379 infraspecific taxa) from 107 genera, 62 families, 32 orders, and 3 classes Bacillariophyta. Eighty-five taxa are in need of further research and confirmation of previous records is necessary. Benthic diatoms are of low diversity and in phytoplankton the species richness is significant among tihopelagic forms (51%).
