Description: Unicellular, quadriflagellate, uninucleate alga without cellulosic cell walls. Cells 2-4 um wide and 7-10(-12) um long, fusiform and bent into an arc, such that one side of cell is concave, the other convex; cells sometimes longitudinally twisted. Cell anterior narrowly rounded and bearing four whiplash flagella longer than cell. Two contractile vacuoles near base of flagella. Cell posterior narrowly elongate and acuminate. Chloroplasts single, parietal along convex side of cells, with anterior stigma and without pyrenoid. Asexual reproduction by longitudinal binary fission. Globose cysts, 5.5-7 µm wide present. Biflagellate cells recorded and presumed to be gametes, however, syngamy not observed.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
