Description: Small-to-medium-sized (18-55 µm) thecate dinoflagellate of spherical shape with a median and circular cingulum. Sulcus restricted to the hypocone, has at the left side a conspicuous list and is characterized by a prominent flagellar pore. A small apical horn may be present. Plate formula: Po, X, 3', 1a, 6", 4c, 6s, 5"', 2"". First apical plate 5-sided. Thecal plates smooth, sometimes with broad intercalary bands. Cytoplasm clear, nucleus spherical, no chloroplasts, nutrition by pallium-feeding on diatoms and other phytoplankton. Cysts round, smooth, brown in color. Marine plankton, in coastal waters. Emend.

Numbers of names and species: There are 4 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
