Taxonomic status: currently recognized as a distinct genus.
Description: Ovoid or cylindrical, unflattened, rigid, strongly keeled cells, with one emergent flagellum, held anteriorly and highly mobile during rapid swimming; colorless, osmotrophic, with abundant paramylon grains of various shapes; cells mostly small (ca. 25 _m long) though the type may reach 45 _m. Regarded by Pringsheim (1963) as colorless derivatives of Lepocinclis but Christen (1962b) finds this unlikely. Rare; freshwater, acidic habitats, especially ponds and ditches with decaying vegetation; recorded from Latvia, France, Switzerland and the Ukraine.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
