Holotype species: Amphidiniopsis kofoidii Woloszynska

Original publication and holotype designation: Woloszynska, J. (1929 '1928'). Dinoflagellates der polnischen Ostsee sowie der an Piasnica gelegenen Sumpfe. Archiwum hydrobiologii i rybactwa 3: 153-278.

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, [1]-560, 421 figs. Berlin: Springer Spektrum.

Description: Epicone much shorter than hypocone. Cells bilaterally or dorsoventrally distinctly compressed. Cells surrounded by distinct amphiesmal plates. The plate formula given for the type species was 3', 7'', 5''', 2''''. Chloroplasts absent.

Information contributed by: Moestrup & Calado (2018). The most recent alteration to this page was made on 24 Oct 2018 by M.D. Guiry.

Characters considered diagnostic of Amphidiniopsis: Hoppenrath (2001), based on studies of several marine species, gave the plate formula: po, 4', 1–3a, 6–8'', 5–8c, 3–5s, 5–6''', 2''''.

Comments: Nutrition phagotrophic, no chloroplasts. Sexual reproduction and cyst formation not known. Marine, sand-dwelling, sometimes washed into the plankton. According to Moestrup & Calado (2018: 284), the "... type species originally described from brackish water in the Baltic, and several marine species are now known. A freshwater species was subsequently found in a lake in Canada in 1997. Molecular analysis of some marine species of Amphidiniopsis (SSU rDNA) has shown phylogenetic relationship between these species and Protoperidinium (Hoppenrath et al. 2012)."

Numbers of names and species: There are 25 species names in the database at present, of which 24 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.
