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]

Identification Amphidinium steinii, Amphidinium trulla, and Amphidinium cupulatisquama are similar species. This species was previously identified under the names A. operculatum var. gibbosum (Maranda and Shimizu 1996), A. klebsii (Blanco and Chapman 1987, Taylor 1971 a, b), and A. “belauense” (McNally et al. 1994).  [details]
