Cysts of the genus Protoperidinium species in sediments from coastal waters of Phu Yen, Khanh Hoa and Ninh Thuan provinces, South central Vietnam

Abstract

Eight different types of cysts belonging to the genus Protoperidinium were recorded in sediments sampled at seven stations in the coastal waters of South Central Viet Nam. All types of cysts are firstly described and discussed in detail. Among them, Protoperidinium latissimum, P. conicum, P. cf. shanghaiense, and Protoperidinium sp.3 that have the saphopylic archeopyle type correspondent to 2a paraplate; P. parthenopes and Protoperidinium sp.2 (Islandinium brevispinosum) are characterized by a saphopylic archeopyle comprising three apical paraplates.
