Description
Cells dorso-ventrally flattened, c. 36.25 microns (33.88-38.62 microns, n = 15) long, c. 33.83 microns (31.3-36.36 microns, n = 15) wide and c. 5 microns (n = 1) deep. The hypocone is w-shaped and the epicone is sharply conical, giving the cell a markedly angular outline. Each lobe of the hypocone can be indented at times. The apical groove is straight, extending down 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 oval and on the left side of th hypocone. An extension to the sulcus is present on the epicone. The cingulum is displaced by one cingulum width. Chloroplasts are numerous, yellow-green and variable in shape. Preserved chloroplasts become circular.
