Seven species of hyaline Tintinnina were obtained from plankton samples collected near the coastal reefs of Ponta do Seixas (Lat. 7º09'16"S, Long. 34º4735"W), Northeastern Brazil, from April 1981 to May 1982 and from April 1983 to May 1984: Amphorellopsis acuta (Schmidt, 1901), Dadayiella ganymedes (Entz Sr., 1884), Epiplocyloides reticulata (Ostenfeld & Schmidt, 1901), Eutintinnus tubulosus (Ostenfeld, 1899), Favella ehrenbergi (Claparède & Lachmann, 1858), Metacylis mereschkowskyi Kofoid & Campbell, 1929 and M. perspicax (Hada, 1938). The most frequent and abundant species were M. mereschkowskyi and F. ehrenbergi. Except/).ganymedes, E. reticulata and F. ehrenbergi all species are new records from Brazil. Metacylis perspicax is also the seventh world register. For all species we provide description, drawings, measurements, seasonal occurrence, world distribution and some systematic comments.
