Cells rounded, asymmetrical, 18.0−29.0 µm x 15.7−34.9 µm; epicone and hypocone equal. Epicone hemispherical, slightly tilted to the left side, hypocone cup-shaped. Cingulum medial, wide, deep, descending (offset 0.5-1.0), at the intersection of cingulum and sulcus epicone forms protrusion strongly drawn to hypocone. Sulcus wide, V-shaped, located only on hypocone, reaches antapex. Nucleus large, usually located in the center. Chloroplasts numerous, fulvous, located at the periphery of the cell.
