Diagnosis: Locomotive form fan-shaped, often with pronounced tail or discoid. Anterior margin smooth and rounded; posterior margin often triangular. Frontal hyaloplasm occupies about 2/3 of the total cell area or even more. Greatest dimension of the locomotive form 10€”30 µm (average 16€”21 µm). Single vesicular nucleus 3.4€”5.0 µm in diameter with rounded central nucleolus. Floating form with long tapering pseudopodia far exceeding the diameter of the central mass. Cell surface is covered with glycostyles about 110 nm in length; simple, filaments present among them.

 

Ecology: Freshwater.
