The ornamentation of this new species is peculiar, and characterized by smooth valves with large pores (0.32{\textendash}0.50 μm) scattered on their surface, except in two circular patches of \~{}15 μm in diameter, devoid of ornamentation and located on both sides of the valve centers. The periflagellar area is widely triangular, located in a moderate excavation of the right valve, and comprises nine platelets. The intercalary band of P. bimaculatum is smooth. The molecular phylogenetic position of this new taxon was inferred from SSU and LSU rDNA genes. In both phylogenetic analyses, P. bimaculatum branched with high support with Prorocentrum consutum and formed a clade sister to the one including P. lima and related species such as P. arenarium, P. belizeanum, P. hoffmannianum, and P. maculosum. From the phylogenetic study, since most species related to P. bimaculatum are known for their toxic effects and production of okadaic acid, this new species can be considered as a potential toxin producer, but this has to be analyzed.}, doi = {10.1111/j.1529-8817.2011.01102.x}, author = {Nicolas Chomerat and Maria Saburova and Gwenael Bilien and Faiza Al-Yamani} } @article {13, title = {BARRUFETA BRAVENSIS GEN.

In this study, detailed morphological observation of Coolia species from Malaysian waters was carried out using light and electron microscopy in parallel with molecular characterization of nuclear-encoded partial LSU rDNA, and internal transcribed spacer (ITS) regions. Live specimens were collected from seaweed samples and established into clonal cultures. There are significant morphologial variations between the Malaysian isolates in comparison to the type species, C. monotis Meunier. the feature that differentiates the new species is the third postcingular plate (3{\textquoteright}{\textquoteright}{\textquoteright}), which is the largest hypothecal plate in the Malaysian isolates, whereas in C. monotis, the 3{\textquoteright}{\textquoteright}{\textquoteright} and 4{\textquoteright}{\textquoteright}{\textquoteright} plates are almost equal in size. Detailed observations of the thecal pores also revealed the presence of fine perforations within the pores of the Malaysian isolates, but these perforations are absent in C. monotis. Comparisons between Malaysian isolates and C. monotis nucleotide sequence of the ITS region showed high genetic divergence at 28\%, in contrast to the 0.3\%-3\% divergence observed among populations of the same species. Structural comparison of the second internal transcribed spacer (ITS2) rRNA transcript between the two species showed compensatory base changes (CBCs) in the three helices of ITS2 rRNA. Based on morphological and molecular data, the Malaysian isolates are considered to represent a new species, for which the name Coolia malayensis is proposed.}, keywords = {benthic dinoflagellates, Coolia malayensis, ITS2 rRNA transcript, morphology, phylogeny}, doi = {10.1111/j.1529-8817.2009.00778.x}, author = {Chui-Pin Leaw and Po-Teen Lim and Kok-Wah Cheng and Boon-Koon Ng and Gires Usup} } @article {10, title = {Morphology and molecular phylogeny of Prorocentrum consutum sp. nov.

Cells have a subcircular to broadly ovoid shape and are plainly flattened. They are 57-61 microns long and 52-55 microns wide. A central pyrenoid is present, and the kidney-shaped nucleus is positioned in the posterior region. In right valve view, the periflagellar area is deeply excavated, and the left valve forms a proinent apical ridge. The periflagellar area consists of nine platelets, and a small narrow collar is present around the flagellar pore. The ornamentation of this new species is very peculiar and is characterized by a ring of round areolae located at the peripherhy of the valves, each areola containing three or four pores. Apart from this ring of areolae, the cell surface is smooth and with scattered pores. Pores are not present in the center of the right or left valve. The intercalary band is generally narrow and faintly striated horizontally. The molecular phylogenetic position of P. consutum sp. nov. was inferred using SSU and LSU rDNA. In both analyses, this species branched with high support in the clade comprising species with a symmetric shape and appeared to be a sister group to that formed by P. lima and other tropical benthic species, such as P. arenarium, P. belizeanum, P. hoffmannianum and P. maculosum.}, keywords = {dinoflagellates, LSU rDNA, molecular phylogeny, nuclear DNA, Prorocentrum, SEM, SSU rDNA, taxonomy}, doi = {10.1111/j.1529-8817.2009.00774.x}, author = {Nicolas Chomerat and Daniel Y.

The bloom was accompanied by extensive abalone (Haliotis midae) mortalities and noxious gases causing eye, nose, skin and throat irritations in humans. In 1995, another undescribed gymnodinioid species bloomed in the same bay but with no adverse effects on marine fauna or humans. These two species form an established component of the phytoplankton assemblage on the south coast of South Africa. They are described here as Karenia cristata Botes, Sym \& Pitcher and K. bicuneiformis Botes, Sym \& Pitcher. Karenia cristata has a straight apical groove elevated into an apical crest and extending down immediately to the right of the sulcal extension on the ventral side. The hypocone is asymmetrical, with the right lobe larger and more rounded than the left; the nucleus is central, with the bulk situated in the hypocone. Its pigment content is similar to that of K. mikimotoi and K. brevis. Other than K. brevis, K. bicuneiformis is significantly larger than the other Karenia species and is distinctly dorso-ventrally flattened. The hypocone is w-shaped and the epicone is conical, giving the cell a distinctly angular outline. Pairwise distance comparisons of partial large subunit (28S) rDNA sequences indicate that these two species are clearly different from other species within the genus.}, keywords = {Algal blooms, Bay, cristata, Dinophyta, DNA, Genotyping, Gymnodiniales, Karenia, Karenia bicuneiformis, Karenia cristata, Marine, New species, Noxious, Nucleotide, Phenotyping, Phytoplankton, sequence, South Africa, Sp.nov., Taxonomy and morphology}, author = {Botes, L. and Sym, S.
