Description:
Motile cells 1–2 ?m in diameter, spherical or heart shaped. Two unequal flagella, ventrally inserted. Long flagellum 4–7 µm directed forward, with laterally inserted tubular flagellar hairs. Short flagellum 0.9–2.2 µm naked with a marked acronema. Basal apparatus reduced to basal bodies. Dorsal chloroplast occupies about half the cell. Non-motile cells with silicified cell wall. Cell wall composed of three shield plates, three oblong girdle plates, a triradiate dorsal plate with rounded ends and a large ventral plate. For both motile and non-motile cells, one chloroplast with a girdle lamella, lamellae with two to three appressed thylakoids. Mitochondria with tubular cristae.
