Description: Tiny (1-7 µm), pyriform, colorless cell, with one trailing flagellum; not euglenoid in appearance, having an anterior nucleus, no reservoir and a double row of bodies in a groove (suggesting Cryptophyceae). Calway and Lackey (1962) place it close to Clautriavia; Bourrelly (1970) suggests it might be a bodonid; Patterson and Zölffel (1991) suggest Cercomonas, a colorless biflagellate with heterodynamic flagella. Polluted freshwaters; very rare, UK and USA.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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