ABSTRACT

Centric diatoms of the cooling pond of the Khmelnitskiy NPS were studied by the method of scanning electron microscopy. A total of 19 species of Bacillariophyta represented by 20 infraspecific taxa was revealed. On the whole, four genera (Conticribra, Cyclostephanos Round, Discostella, and Thalassiosira Cleve) and 13 infraspecific taxa of diatoms were found in the cooling pond for the first time. Aulacoseira tenella (Nygaard) Simonsen and Cyclotella marina (Tanimura, Nagumo et Kato) Ake-Castillo, Okolodk. et Ector. proved to be new for the flora of Ukraine. Illustrations, brief morphological description, and distribution in Ukraine are given for each species.

KEY WORDS: Bacillariophyta, Centrophyceae, electron microscopy, the cooling pond of the Khmelnitskiy NPS.
