Original description: Cell sphaeroidal to ovate. (6)-8-12(-16) µm diam or long. Two equal or subequal flagella. (15-)18-24(-27) µm long; haptonema (6-)10-14(-16) µm long. Chromatophores usually 2. lobed and parietal. Single pyrenoid 1.5-2 µm diam, Iocated in the mid-region of the cell; stigma absent. Large contractile vacuole near bases of the haptonema and flagella at anterior pole. Food vacuole near posterior pole sometimes containing refractive material up to 3 µm diam. Nucleus located in the mid-region of the cell with conspicuous nucleolus 0.5-1 µm diam. Cell body covered with delicate organic scales of two types: an inner layer of oval plate stales (0.8-1.2 µm long; 0.5-0.6) µm wide) with a sculptured pattern of fine concentric lines and radiating ridges on the disial surface and a pattern of parallel ridges on the proximal surface; outer scales consisting of a base-plate similar in size to the underlying plate scales, but supporting centrally a short. delicate, blunt-ended spine with a club-shaped terminus. Spines attached to the base-plate by two to several branching arms arising from division of the spine about mid-way between the base-plate and the distal end of the spine. Total height of the spine above the base-plate, including supporting structures. 0.4-0.6 µm.
