General environment
This is a marine species.

Description
Cells pentagonal in outline, 19-29 microns long and 15-25 microns wide. Epicone conical and acute, with a large ventral pore approximately halfway between the anterior sulcal termination and the beginning of the apical groove. Apical groove relatively short, covering 1/3 of the ventral epicone and 1/4 of the dorsal side. Hypocone rectangular, obviously truncated by the sulcus. Cingulum displaced approximately1/4 of the cell length. Sulcus sinusoidal, with a tube-shaped structure, and extending into the epicone as a finger-like projection. Chloroplasts long and ribbon-like, arranged into bands on the cell periphery. Nucleus small and round, located at the antapex of the cell.

Type information
Type locality: Southern Ocean (44º40'S, 147º06'E), directly south of Tasmania, Australia (Salas et al. 2008: 249). Holotype: Fig. 6 (epitype) March 2006; Water temperature of 17ºC. (Salas et al. 2008: 248, 242). Notes: Holotype: Fig. 6, an illustration of cells from the clonal culture KDCSO15, deposited in the Univ. of Tasmania's Collection of Microalgae; also comprises the 28S rDNA sequence stored under GenBank accession number EF469231.
