Original description: Chloroplast containing cells, 2-5 µm in diameter when dried, possibly up to twice as large when living, with two subequal flagella, 7-14 µm and 9-17 µm in length and a coiling haptonema, 3-4 times longer than the flagella. Body covered by a single, delicate scale type, slightly ovate in outline, 0.4-0.6µm x 0.5-0.8µm in size. The proximal scale face with a radial fibrillar pattern of 35-55 lines, divided into four quadrants. The distal face with an identical radial pattern, on which is superimposed an irregular circular pattern of c. 20 non-concentric lines.
