Original description: Protoplast globose to anisodiametric, c. 8-13 µm when dry but probably up to 50% larger alive, with two equal flagella, each up to 30 µm long and a haptonema somewhat though not much shorter. Periplast scales large, flat, and of two kinds, evenly distributed and respectively with and without centrally attached, rigid, slender spines each up to 3 µm long × 0.05-0.1 µm thick, bluntly pointed. Both scale-types with narrow patternless rims but the base plates of spines a little smaller and more circular than the spineless plates. The latter commonly 1.3 × 1.6 µm. Surface patterning similar in both scale-types, the proximal faces dominated by radial ridges arranged in quadrants and the distal faces by a few, well separated, spiral threads coiled in an anticlockwise direction if seen from above and interpreted centripetally. This direction continuing up every spine to give a twist of about 21⁄2 turns along its length. Both scale faces exhibiting traces of other components located between the surfaces of the scale.
