Taxonomic status: currently regarded as a synonym of Gymnodinium.

Most recent taxonomic treatment adopted: Moestrup, Ø. & Calado, A.J. (2018). Süßwasserflora von Mitteleuropa. Freshwater Flora of Central Europe, Volume 6: Dinophyceae. pp. [i]-xii, [1]-560, 421 figs. Berlin: Springer Spektrum.

Taxonomic notes
Order Suessiales (Siano et al. 2009: 52). - (6 Mar 2009) - Wendy Guiry

Description: Small free-living more or less cylindrical unicells. By contrast to other gymnodinoid dinoflagellates, a well-developed cingulum is lacking, but flagella are present. Cells with many chloroplasts. This taxon needs reinvestigation as it may be a transitory stage in the life cycle of other dinoflagellates. The type species has been transferred to Gymnodinium Stein, a move supported by a later detailed study which may not have dealt with the species of Lohmann.

Information kindly contributed by M. Elbrächter but may now be outdated.

Numbers of names and species: There are 5 species names in the database at present, of which 5 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
