title: Are Protoperidinium knipowitschii from the Sea of Azov and the Western Mediterranean P. paulseni (Dinoflagellata: Peridiniales) Synonymous?
abstract: Thecal morphology and morphometry of the planktonic dinoflagellate Protoperidinium paulseni (Pavill.) Balech were studied in samples taken in the northwestern Black Sea (Odessa Bay). Using epifluorescence microscopy and SEM, data on the apical pore complex, apical intercalary, sulcal and cingular plates were obtained for the first time; the presence of the hypothecal pore in the 1”’ plate is also reported for the first time. The epitheca morphology was clarified (para 1’ and hexa 2a plates). Cel
