Type designated in Loeblich, A.R., Jr & Loeblich, A.R., III (1966). Index to the genera, subgenera, and sections of the Pyrrhophyta. Studies in Tropical Oceanography 3: 1-94.
Taxonomic status: currently recognized as a distinct genus.
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, -560, 421 figs. Berlin: Springer Spektrum.

According to Lindberg et al. (2005: 425), the species of Woloszynskia fall into at least three groups and this raises the question about the taxonomic position of the type species. Moestrup et al. (2008) place Symbiodinium sp., Polarella glacialis, Woloszynskia pseudopalustris and W. halophila in the same group (Group II). They note that the family name Sussiaceae is available for members of Group II but that inclusion of the entire group will require emendation. - (5 Mar 2009) - Wendy Guiry
Description: Cells covered by many amphiesmal plates, of which those on the epicone are thin, smooth, whereas those on the hypocone are thicker, with distinct raised rims, giving the hypocone a honeycomb appearance. Cysts spherical or slightly rhomboid, covered by amphiesmal plates. The plates remain attached along one margin, thereby standing at right angles to the periphery of the cell. This gives the cyst a spiny appearance.

Numbers of names and species: There are 24 species names in the database at present, as well as 1 infraspecific names. Of the species names, 2 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
