Original description: The cell (Fig. 1) is spherical to ovate, 6-10 µm diameter or long. Two equal or subequal flagella, 18-24 µm long and ahaptonema 8-14 µm long is anteriorly inserted. Chromatophores usually two, parietal and lobed; pyrenoid not observed; stigma present. A large contractile vacuole is near the base of the flagella. At posterior end of the cell is a food vacuole. The cell body is covered with delicate organic scales of only one type: oval scales (Fig. 2; 0.26-0.32 µm long; 0.15-0.20 µm wide) with no sculpturing or fine concentric lines or radiating ridges; upturned rim present.
