Almost 80 years ago, a radiation scheme based on structural resemblance was first outlined for the marine order Dinophysiales. [] Key Method Nuclear-encoded LSU rDNA sequences including domains D1-D6 from 27 species belonging to Dinophysis Ehrenb., Ornithocercus F. Stein, Phalacroma F. Stein, Amphisolenia F. Stein, Citharistes F. Stein, and Histioneis F. Stein were obtained from the Indian Ocean. Previously, LSU rDNA has only been determined from one of these. In Bayesian analyses, Amphisolenia formed a long…
PHYLOGENY OF FOUR DINOPHYSIACEAN GENERA (DINOPHYCEAE, DINOPHYSIALES) BASED ON rDNA SEQUENCES FROM SINGLE CELLS AND ENVIRONMENTAL SAMPLES 1
TLDR
This was the largest molecular phylogeny of dinophysoid taxa performed to date and was consistent with the view that the genus Phalacroma may not be synonymous with Dinophysis.
Molecular phylogeny ofSinophysis: Evaluating the possible early evolutionary history of dinophysoid dinoflagellates
TLDR
A broad sampling of molecular phylogenetic data was used to test whether the relatively streamlined theca, hetero-trophic mode of nutrition and a … to test the sister relationship between Sinophysis and Oxyphysis, which received weak statistical support.
Cryptic diversity of small‐sized species of Phalacroma (Dinophysales, Dinophyceae) from Denmark Strait (Eastern Arctic Greenland)
TLDR
This study has revealed the existence of cryptic species diversity within the Phalacroma morphotype boundary and has to be described as a new genus pending additional data.
MOLECULAR PHYLOGENY OF DINOPHYSOID DINOFLAGELLATES: THE SYSTEMATIC POSITION OF OXYPHYSIS OXYTOXOIDES AND THE DINOPHYSIS HASTATA GROUP (DINOPHYSALES, DINOPHYCEAE) 1
TLDR
The dinophysoid dinoflagellates are currently divided into three families: Amphisoleniaceae, Dinophysaceae, and Oxyphysaceae, but, tentatively, a separate family for the clade of the type and most of the Phalacroma species is proposed.
Nuclear, Mitochondrial and Plastid Gene Phylogenies of Dinophysis miles (Dinophyceae): Evidence of Variable Types of Chloroplasts
TLDR
The detection of the cryptophyte and haptophyte plastid sequences indicates that the natural assemblage of D. miles likely retain more than one type of plastids from its prey algae for temporary use in photosynthesis, which suggests that more systematic research is required to understand the complex nutritional physiology of this genus of Dinophysis species.
Phalacroma gibbosum sp. nov. (Dinophyceae) from the southern Gulf of Mexico
TLDR
During a survey of the phytoplankton from the southern Gulf of Mexico, three specimens of an unknown dinophysoid species were found in formalin-fixed net samples, and were studied by light and scanning electron microscopy.
Species diversity of dinophysoid dinoflagellates in the Clarion–Clipperton Fracture Zone, eastern Pacific
TLDR
Almost half the number of species recorded before in the eastern Pacific (including coastal samples) was observed, corresponding to about one-fifth of the known dinophysoid diversity.
Sinophysis and Pseudophalacroma are Distantly Related to Typical Dinophysoid Dinoflagellates (Dinophysales, Dinophyceae)
TLDR
New SSU rDNA sequences of Pseudophalacroma (pelagic) and Sinophysis (the only benthic dinophysoid genus) are provided and molecular phylogenies support that they are very divergent with respect to the main clade of Dinophysales.
Dinophysiales (Dinophyceae) of the National Park Sistema Arrecifal Veracruzano, Gulf of Mexico, with a key for indentification
The morphology of 38 species from eight genera of the order Dinophysiales was studied based on about seven hundred 20 μm phytoplankton net samples taken from May 2005 through April 2008 at 27
Dinophysiales (Dinophyceae) no extremo Sul do Brasil (inverno de 2005, verão de 2007)
The dinoflagellates of the Dinophysiales order are a morphologically diverse and ecologically heterogeneous group that includes autotrophic, mixotrophic and heterotrophic species and others

GENETIC VARIABILITY AND MOLECULAR PHYLOGENY OF DINOPHYSIS SPECIES (DINOPHYCEAE) FROM NORWEGIAN WATERS INFERRED FROM SINGLE CELL ANALYSES OF rDNA 1
TLDR
RDNA sequences of the most common Dinophysis species in Scandinavian waters are determined and phylogenetic relationships within the genus and to other dinoflagellates are resolved, indicating an early divergence of Dinoph kidney within the Dinophyta.
GENETIC VARIABILITY AND MOLECULAR PHYLOGENY OF DINOPHYSIS SPECIES ( DINOPHYCEAE ) FROM NORWEGIAN WATERS INFERRED FROM SINGLE CELL ANALYSES OF rDNA
TLDR
RDNA sequences of the most common Dinophysis species in Scandinavian waters were determined and phylogenetic relationships within the genus and to other dinoflagellates were resolved to indicate an early divergence of Dinoph kidney within the Dinophyta.
PHYLOGENETIC EVIDENCE FOR THE CRYPTOPHYTE ORIGIN OF THE PLASTID OF DINOPHYSIS (DINOPHYSIALES, DINOPHYCEAE) 1
Photosynthetic members of the genus Dinophysis Ehrenberg contain a plastid of uncertain origin. Ultrastructure and pigment analyses suggest that the two‐membrane‐bound plastid of Dinophysis spp. has
Morphological variability of the potentially toxic dinoflagellate Dinophysis sacculus (Dinophyceae) and its taxonomic relationships with D. pavillardii and D. acuminata
TLDR
Details of morphological variation in D. sacculus are provided throughout its geographical range, which includes the Mediterranean Sea and European Atlantic coasts, and its relationship with D. reniformis (Pavillard) comb is clarified.
Marine planktonic dinoflagellates of the order Dinophysiales (Dinophyta) from coasts of the tropical Mexican Pacific, including two new species of the genus Amphisolenia
TLDR
The number of species found in this study is relatively low, but certain species of Dinophysis, reported in previous papers, do not seem to occur in Mexican waters, as their distribution is rather limited to the Mediterranean Sea and the North Atlantic, respectively.
The marine dinoflagellate genus Dinophysis (Dinophyceae): photosynthetic, neritic and non-photosynthetic, oceanic species
TLDR
The dinoflagellate genus Dinophysis, as currently circumscribed, includes forms with elevated epitheca and straight horizontal girdle lists (species previously allocated to Phalacroma) and forms with reduced epithecas and the girdled lists curved up anteriorly from the cell body (Dinophysis sensu stricto).
Dinophysis diegensis is a life history stage of Dinophysis caudata (Dinophyceae, Dinophysiales) 1
TLDR
It is proposed that Dinophysis diegensis–like specimens should be considered as a taxonomic (or heterotypic) synonym of Dinophsis caudata, and its small and intermediate cells, since its original description by Saville‐Kent in 1881.
Sequence-based diagnostics and phylogenetic approach of uncultured freshwater dinoflagellate Peridinium (Dinophyceae) species, based on single-cell sequencing of rDNA
TLDR
A sequence-based diagnostics for uncultured Peridinium cells from field samples was applied, and could clearly resolve P. bipes f.
