Abstract

The aim of this study was to describe the morphology of species of the benthic dinoflagellate genus Sinophysis from the tropical South Atlantic. Species were collected from four sampling sites and were identified based on light and epifluorescence microscopy. Sinophysis microcephala was found at three sites. Cells were elongated and oval in lateral view. Sinophysis canaliculata was recorded at two sites. Cells were round in lateral view and a short cut was present at the H2 plate. To the best of our knowledge, this is the first record of the genus Sinophysis from the South Atlantic Ocean.

Keywords: benthic dinoflagellates; morphospecies; Sinophysis canaliculata; Sinophysis microcephala; taxonomy
