摘要：

Planktonic samples obtained from the first 30 meters of water column of the Golfo San Jorge/Argentina in November and December, 1984 contain (per liter) up to 3700 free calcareous cysts and parental cells liberating cysts of the marine dinoflagellate theca.Scrippsiella patagonica sp. nov. The ovoid cysts are covered by a calcareous wall constructed by one layer of large, irregularly sized calcite crystals. These Recent cysts show morphological affinities with common Mesozoic fossil cysts of theObliquipithonella loeblichii (Bolli, 1974) group sensu Keupp (1981). Using separate classifications for both motile thecate stages and cysts, the cysts ofScrippsiella patagonica are introduced asObliquipithonella irregularis sp. nov. © 1990 Elsevier Science Publishers B.V.
