Original description: With the characters of the Order. [Motile or palmelloid unicellular organisms; if non-motile, producing motile swarmers. Motile cells with two unequal, often anisokont, heterodynamic flagella and a haptonema; the shorter flagellum sometimes reduced to a vestigial structure.] Cells compressed or not compressed; flagella and haptonema inserted ventrally or laterally, the anterior flagellum bearing a garniture of fine hairs alone or fine hairs with small dense bodies; the posterior flagellum often bearing fine hairs but never with dense bodies; the haptonema demonstrating in the free part progressive distal reduction in the number of microtubules from approximately 8 at the base. Stigma present or absent. A pit or canal present penetrating the cell in front of the anterior flagellum, sometimes associated with the stigma, if present. Storage metabolite in the form of refractive bodies, known to be paramylon in some species.
