Original description: Chloroplast containing cells, round, 6-10µm in diameter, with two equal flagella, 22-25 µm in length and a haptonema, longer than the flagella, in 20-25 coils in fixed specimens. Cell body enclosed within a two layered scale case. Inner layer scales round to slightly ovate, 0.8-1.2µm in diameter with a radial pattern divided into four quadrants on the proximal face, the distal face with a central random pattern surrounded by a radially patterned rim with a central, narrow, raised ridge. Outer layer scales with 6-8 µm long spines attached to cup shaped base scales by four arched struts. Strut surfaces covered with a delicate, random pattern. Spine base scales similar to underlayer plate scales but with a 0.2 µm high upturned rim with a circular pattern, to which the spine struts attach.
