The objective of the present study is to report for the first time the occurrence of Spermatozopsis similis H. R. Preisig et M. Melkonian in a marine environment, describing the morphology and its abundance in Ría del Jabalí; Bahía Anegada, Buenos Aires, Argentina. Samples were taken monthly between June and November 2006 and were observed under light and scanning electron microscope. Specimens of S. similis showed biflagellate, fusiform and slightly spiraled cells, with flagella of unequal length. S. similis was an important component of phytoplankton in Ría del Jabalí between June and August 2006, reaching its maximum abundance in August (6 770 cél.ml-1), during this period there were observed very high and fluctuating values of salinity. This paper is the first record of S. similis in a marine environment.
