Type designated in Bourrelly, P. (1957). Recherches sur les Chrysophycées. Morphologie, phylogénie, systématique. Revue Algologique: Mémoire Hors-Série 1: [1]-412.

Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Bendif, El M., Probert, I., Schroeder, D.C. & Vargas, C de (2013). On the description of Tisochrysis lutea gen. nov. sp. nov. and Isochrysis nuda sp. nov. in the Isochrysidales, and the transfer of Dicrateria to the Prymnesiales (Haptophyta). Journal of Applied Phycology 25: 1763-1776.

Comments: Dicrateria inornata Parke - no designation in Parke 1949, but Green & Pienaar 1977 considered that the other species, D. gilva Parke, was in need of re-isolation and re-investigation. Jordan et al. (2005) have therefore assumed that D. inornata is the type species. Throndsen (1997: 635) record this genus as being a member of the Family Gephyrocapsaceae.

Numbers of names and species: There are 4 species names in the database at present, of which 3 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.
