General environment
This is a marine species.

Description
Cells dorso-ventrally flattened, c. 25.7 microns (24.05- 27.35 microns, n = 15) long, c. 24.29 microns (21.79-26.79 microns, n = 15) wide, c 10 microns (n = 1) deep. The hypocone is asymmetrical, with a larger and more rounded right lobe.The apical groove is straight and elevated into an apical crest, extending to the cingulum-sulcus junction on the ventral side of the cell and only a short distance on the dorsal side of the cell. The nucleus is central in the hypocone, but extends somewhat into the epicone. The sulcus extends onto the epicone and flares out to the antapex. The cingulum displaced twice its own width. Chloroplasts are numerous, yellow-green and variable in shape.
