Brownish-green parietal chloroplast with a bulging pyrenoid forming an anterolateral protuberance on the cell body. Motile cells flattened oval, metabolic with three appendages. Distal attenuation of the bipartite posterior flagellum, haptonema short but not vestigial. Stalked ovoid knob-scales may be present. Anterolateral bulging pyrenoid, partially covering and bordering a pit where the flagella emerge, delimited from the chloroplast stroma by osmiophilic globules forming a stigma near the insertion of the appendages.</paragraph>
