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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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