NOV. (DINOPHYCEAE, PROROCENTRALES), A NEW BENTHIC DINOFLAGELLATE SPECIES FROM KUWAIT (ARABIAN GULF)0 aPROROCENTRUM BIMACULATUM SP NOV DINOPHYCEAE PROROCENTRALES A NEW  a211-2210 v483 aA new benthic dinoflagellate species, Prorocentrum bimaculatum sp. nov., is studied from Kuwait’s marine sediments, based on detailed morphological and molecular data. Cells are large, oblong oval in shape. They are 49.9–55.3 μm long and 38.4–43.2 μm wide. The ornamentation of this new species is peculiar, and characterized by smooth valves with large pores (0.32–0.50 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.1 aChomerat, Nicolas1 aSaburova, Maria1 aBilien, Gwenael1 aAl-Yamani, Faiza  uhttps://dinoflagellate.myspecies.info/node/100665nas a2200193   4500008004100000245012400041210006900165300001200234490000700246100002100253700002000274700002100294700002300315700001900338700003200357700001700389700001600406856004900422       2011                        eng d00aBARRUFETA 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’’’), which is the largest hypothecal plate in the Malaysian isolates, whereas in C. monotis, the 3’’’ and 4’’’ 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.10abenthic dinoflagellates10aCoolia malayensis10aITS2 rRNA transcript10amorphology10aphylogeny1 aLeaw, Chui-Pin1 aLim, Po-Teen1 aCheng, Kok-Wah1 aNg, Boon-Koon1 aUsup, Gires  uhttps://dinoflagellate.myspecies.info/node/502273nas a2200265   4500008004100000245015900041210006900200260001200269300001200281490000700293520144500300653002001745653001301765653002401778653001601802653001701818653000801835653001301843653001301856100002201869700002301891700002201914700002201936856004901958       2010                        eng d00aMorphology 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.10adinoflagellates10aLSU rDNA10amolecular phylogeny10anuclear DNA10aProrocentrum10aSEM10aSSU rDNA10ataxonomy1 aChomerat, Nicolas1 aSellos, Daniel, Y.1 aZentz, Frédéric1 aNézan, Elisabeth  uhttps://dinoflagellate.myspecies.info/node/600543nas a2200145   4500008004100000245012600041210006900167300001400236490000700250100002400257700002500281700002100306700002100327856004900348       2009                        eng d00aDESCRIPTION OF TYRANNODINIUM GEN.
