Cells contain numerous yellow-brown chloroplasts. Dorso-ventrally flattened cells with open horns. The epitheca is rounded with sharp transition to the long, straight, slender anterior horn. The hypotheca is extending into two antapical horns at its posterior edges. They emerge in a posterior direction, but after curving, are directed anteriorly, nearly parallel with the anterior horn. The thecal plates are ornamented. Plates in the central area on the ventral side are very delicate. The nucleus is situated in the epicone.
