Abstract: Peridinium is an important genus of freshwater armoured dinoflagellates with two more intercalary plates (sensu Bourrelly). A few species of Peridinium were known from China heretofore. The plate pattern is one of the important criteria for the taxonomy of Peridinium, and it was difficult to visualize their plate patterns under normal light microscope. For editing of Flora Algarum Sinicarum Aquae Dulcis, 11 species of Peridinium col-lected from various freshwater habitats of China are described. Among them, 6 species are first reported from China. They are P. gatunense Nygaard, P. gutwinskii Woloszynska, P. lomnickii Woloszynska, P. palatinum Lauterborn, P. striolatum Playfair, and P. zonatum Playfair. Epifluorescence microscopy and scanning electron microscopy, and also light microscopy were employed for their structure and patterns of thecal plates.
