(Dinophyceae)0 aMorphology and molecular characterization of a new species of th  c02/2010  a162-1710 v463 aCoolia Meunier is an important component of benthic dinoflagellate assemblages in tropical and subtropical seas. 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/500543nas a2200145   4500008004100000245012600041210006900167300001400236490000700250100002400257700002500281700002100306700002100327856004900348       2009                        eng d00aDESCRIPTION OF TYRANNODINIUM GEN.

Other similarities between Katodinium rotundatum and Heterocapsa include the presence of triangular scales on the cell surface, the pyrenoid structure and the structure of the flagellar apparatus. Katodinium rotundatum is transferred to Heterocapsa as this name has priority. It is indicated that scale morphology is superior to thecal plate pattern for identification of Heterocapsa species and should be included in future diagnoses of them. The organism described as Heterocapsa quadridentata Stein is transferred to Peridinium, as Peridinium quadridentata (Stein) comb. nov.10aUltrastructure.Dinophyceae1 aG., Hansen  uhttps://dinoflagellate.myspecies.info/node/9
