Original description: Cells saddle shaped measuring 4-6 µm with two chloroplasts. Two flagella, usually equal 8-18 pm. Haptonema 22-80 µm long, coiling. Periplast covered with dimorphic scales, in two layers; outer layer scales slightly elongate, 450-570 x 350-470 nm, with spine supported by four decurrent struts, spine approximately equalling the scale radius; inner layer scales slightly elongate, 400-550 x 320-460 nm, without protrusions.
