Description: Free-swimming, biflagellate monads with dorsiventral symmetry, the anterior obliquely truncate, posterior tapering and rounded, the protoplast weakly torsioned; with two lateral, yellow-brown chloroplasts, often lobed; usually with two contractile vacuoles, one of these always anterior; with many small refractive granules present in the posterior; the starch granular; the flagella subequal, homodynamic, inserted in vestibulum. Division occurs in the motile state through a longitudinal plane that sustains cell symmetry; palmelloid colonies and cysts have not been observed. An enigmatic genus that Butcher (1967) reduced to synonomy with Chroomonas. It is retained as a separate genus here, however, as it clearly does not fit into the more recent definitions of Chroomonas (Santore 1984, Hill 1991) and may, in fact, represent a valid genus of freshwater cryptomonads.

Verification of Data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
