Description: Medium-sized (22-52 _m) biflagellated subglobular, dorsiventral slightly flattened cell, with a median cingulum which is slightly displaced. Sulcus with apical groove, narrow at the epicone, broad at the hypocone, reaching the antapex. Protoplast covered by more or less quadratic, hand basket-shaped scales, produced in the Golgi apparatus of submicroscopical size ca. 250 nm long and ca. 270 nm high. At the junction of the cingulum and the sulcus a protoplasmic projection of unique ultrastructure is situated. The cell contains an endosymbiont of the prasinophyte lineage based on its chloroplast ultrastructure and pigmentation. In contrast to normal dinoflagellates, this organism contains no peridinin and chlorophyll c, but chlorophyll b and violaxanthin, zeaxanthin, _-carotene, etc. The endosymbiont is separated from the host by 2 membranes, but it does not contain a nucleus or mitochondria. Reproduction not reported. Marine plankton, in coastal waters off Japan.

Numbers of names and species: There are 2 species names in the database at present, of which 2 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..

Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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