First Record of Borghiella dodgei (Dinoflagellata) in Eastern Europe

The morphology of rare cryophilic species of dinoflagellates Borghiella dodgei Moestrup, Hansen & Daugbjerg from Eastern Europe (Kiev, Ukraine) has been studied. Until now, only two locations of this species—freshwater reservoirs in Italy and Portugal—were known. The original description of B. dodgei from the new locality, drawings, and photos are given in this work. The morphological variability, ecology, and distribution of B. dodgei are discussed.
