Nomenclatural notes
Ceratoperidinium R.Margalef, Invest. Pesq. 33: 351. Jan 1969 was invalid as it lacked a Latin diagnosis. - (30 Sep 2014) - M.D. Guiry

Description: Unarmoured dinoflagellates possessing chloroplasts. Acrobase making a circular loop around the apex. Retractile appendices (both apical and antapical) present at least during some life-cycle stages. Cingulum descending, displaced 2-3 times its own width, not overhanging. [Emend. Reñé & de Salas (Escobar-Morales & Hernández-Becerril, 2015)].

Information contributed by: Reñe et al. (2013). The most recent alteration to this page was made on 11 Oct 2018 by M.D. Guiry.

Comments: "Ceratoperidinium differed from other members of the Ceratoperidiniaceae in the high dorso-ventral flattening and presence of two antapical retractile extensions." (Gómez 2018).

Numbers of names and species: There are 4 species names in the database at present, of which 1 has 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
