Description: Unarmoured dinoflagellates with chloroplasts containing internal, lenticular pyrenoids and fucoxanthin or fucoxanthin derivatives as main accessory pigments. Amphiesma with arrays of pluglike structures in a hexagonal configuration. Apical groove straight; ventral pore present. Emended by Bergholtz et al. (2006: 192). Emended by Luo et al.(2018: 411).The most recent alteration to this page was made on 26 Aug 2019 by M.D. Guiry.
Comments: According to Bergholtz et al. (2006: 189), it is not possible to distinguish between the two taxa K. veneficum and K. micrum morphologically, and considering the very small difference in partial LSU, they conclude that the two species are conspecific. This finding leads to a name change for the type species of Karlodinium to K. veneficum, and reduces the name K. micrum to a synonym.
Numbers of names and species: There are 15 species names in the database at present, of which 14 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
