Description Cells are asymmetrical ellipsoid, with a slightly pointed antapex, dorsoventrally flattened. Minute epicone, deflected to the left. Posterior part of the right side of the hypocone is often concave, appearing sigmoid, with a‘‘hump-backed’’ shape. Cingulum deeply incised, with ends displaced. Sulcus originates posteriorly to the cingulum and runs to the antapex. Large 4 μm diameter pusule located beside the origin of the sulcus. Sulcus has a pronounced right bend after about one third of its length, curving slightly to the left. Round nucleus is positioned posteriorly.  [details]
