Most recent taxonomic treatment adopted: Gómez, F., Richlen, M.L. & Anderson, D.M. (2017). Molecular characterization and morphology of Cochlodinium strangulatum, the type species of Cochlodinium, and Margalefidinium gen. nov. for C. polykrikoides and allied species (Gymnodiniales, Dinophyceae). Harmful Algae 63: 32–44, 5 figs.
Description: Unarmored free-living heterotrophic dinoflagellate. Cells are solitary, not forming chained colonies. The deeply constricted cingulum has a descending left-spiral course, turning 1.5–2 times around cell. The sulcus invades the episome as a wide loop, ending near the apex on the dextro-dorsal surface. The apical groove is circular, encircling the apex and connecting with the anterior sulcus. The surface is covered by longitudinal equidistant fine striae. The nucleus is enclosed in a distinct perinuclear capsule.

Numbers of names and species: There are 47 species names in the database at present, of which 29 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.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
