Original description: Haptophyte, marine, photosynthetic, and symbiotic with polycystine radiolarians and foraminiferans. In host, cells spherical and nonmotile. In culture, the haptophyte produces motile cells. Free-living motile cells saddle-shaped, approximately 3–5 μm long and 3–4 μm wide, with appendages inserted apically in a slight depression. Two equal to subequal flagella, 6–12 μm long. One coiling haptonema, 6–16 μm long, slightly longer than the two flagella. Flagella and haptonema originated from the concave, ventral side of the cell, in the apical to median region. Cells covered by two types of scales arranged in two layers. Inner layer was composed of oval to round scales, 0.19–0.26 μm in diameter, and the outer layer composed of oval to round scales, 0.25–0.45 μm in diameter, with upright rims (37–55 nm high). Both scale faces had a faint cross in centre and radiating ridges extended from the faint cross to the periphery. Two golden-brown parietal chloroplasts contained three thylakoid lamellae and immersed pyrenoids. Nucleus on dorsal side of cell in median to posterior region. Golgi body positioned in front of nucleus.
