Abstract
A new species of Dinoflagellata—Protoperidinium euxinum Krachmalny sp. nov. (Protoperidiniaceae, Peridiniales) was described from the plankton of Odessa Bay (Black Sea). The species is morphologically close to P. steinii, P. mediterraneum and P. joergensenii. It differs from the listed species in elongated pentagonal body shape, conical epitheca with straight or concave lateral sides, inverse trapeziform hypotheca, and asymmetrical, laterally compressed plate 2a. Dimensions: 73.3–99.0 µm in length and 38.8–51.6 µm in width. Pictures and photomicrographs of the novel species are presented, along with detailed description and discussion.
