The cell is thecate,  solitary cell of small dimensions. In valve view it appears oval to heart-shaped or even triangular, and laterally compressed. The cell surface is covered in numerous spines (about 600-700 per valve) with a wide base arranged in uniform pattern. In addition there are small pores distributed randomly, and larger pores at the base of some peripheral spines. In the periflagellar region there is a flagellar pore from which emerge 2 flagella and adjacent to which protrudes a small spine. Near the auxiliary pore there is a small periflagellar collar. The cell contains two golden-brown chloroplasts and in the posterior region there is an ellipsoid nucleus.

Cosmopolitan, planktonic, typical of marine and brackish environments.
