This is a marine species.
Cells pentagonal in outline, 19-29 microns long and 15-25 microns wide. Epicone conical and acute, with a large ventral pore approximately halfway between the anterior sulcal termination and the beginning of the apical groove. Apical groove relatively short, covering 1/3 of the ventral epicone and 1/4 of the dorsal side. Hypocone rectangular, obviously truncated by the sulcus. Cingulum displaced approximately1/4 of the cell length. Sulcus sinusoidal, with a tube-shaped structure, and extending into the epicone as a finger-like projection. Chloroplasts long and ribbon-like, arranged into bands on the cell periphery. Nucleus small and round, located at the antapex of the cell.
