[ref. ID; 2014]
Medium-sized ciliate (125-140 um long) that is irregularly oblong in outline shape with a slightly narrower 'waist' region just below the equator; dorso-ventrally flattened. The anterior region is slightly wider than the posterior. The oral aperture is a conspicuous channel beginning apically and extends down a third of the length of the individual. Buccal ciliation is comprised of an undulating membrane on the right of the buccal cavity and 3 membranelles on its left. Somatic ciliation is uniform, made up of rather short cilia and may sometimes be restricted to the anterior two-thirds of the cell. The contractile vacuole is equatorially situated on the cell's right. The ribbon-like macronucleus winds around the apical region. Large trichocysts are distributed beneath most of the surface area of the pellicle. Locomotion of these organism is slow, it is a planktonic feeder and has been observed at considerable depths. Single species genus.
