Description:

Cyranomonas is a biflagellated colourless protist of unknown affinities. Cells are ovoid, 4.5 - 5 µm long, dorso-ventrally flattened, and somewhat flexible. The anterior part is depressed of concave. Two thickened flagella emerge from the right side of the cell and are not acronematic. The anterior flagellum is about the length of the cell and flickers stiffly forwards. The posterior flagellum inserts to the left of the anterior flagellum, is 1.5 the length of the cell, and trails behind the cell. The nucleus is located anteriorly. The cells contain small food materials. The cells glide slowly with the anterior flagellum. C. australis is currently the only species in the genus, which has so far only been reported from Australia.
