Here we established the cyst–theca relationships of 11 species (<i>Boreadinium breve</i>, <i>Diplopelta globula</i>, <i>Diplopsalis lenticula</i>, <i>Diplopsalopsis ovata</i>, <i>Lebouraia pusilla</i>, <i>Niea acanthocysta</i>, <i>Niea chinensis</i>, <i>Niea torta</i>, <i>Oblea rotunda</i>, <i>Preperidinium</i> cf. <i>meunieri</i> and <i>Qia lebouriae</i>) belonging to nine genera by incubating cysts collected along the coast of China. In addition, we obtained 22 large-subunit ribosomal DNA sequences from the germinated motile cells of these 11 species by single-cell polymerase chain reaction. A new genus, <i>Niea</i>, was erected to encompass species with a plate formula identical to that of <i>Oblea</i>, that is, Po, X, 3', 1a, 6'', 3C+t, 5''', 2'''', but with an ortho 1'. <i>Niea chinensis</i> was described based on both theca and cyst morphology. The genus <i>Oblea</i> was emended to incorporate only species with a meta 1'. As a consequence, <i>Oblea acanthocysta</i> and <i>O. torta</i> were transferred to the newly erected genus <i>Niea</i>. A second new genus, <i>Qia</i>, was established to encompass <i>Diplopsalis lebouriae</i>, and the genus <i>Diplopsalis</i> was emended, differing from <i>Qia</i> in the shape of the anterior intercalary (1a) plate. Phylogenetic analyses were carried out using maximum likelihood and Bayesian inference. Molecular phylogeny revealed that the diplopsalioideans were not monophyletic and were subdivided into three clades. From our results, the shape of the first apical and anterior intercalary plates and the number of apical, anterior intercalary and antapical plates were useful characteristics to distinguish the diplopsalioideans at the genus level.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Cyst-theca relationship and phylogenetic positions of the diplopsalioideans (Peridiniales, Dinophyceae), with description of <i>Niea</i> and <i>Qia</i> gen. nov.","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Cyst; Diplopsalis lenticula;Diplopsalopsis ovata; Lebouraia pusilla; Oblea acanthocysta; Oblearotunda; Oblea torta; Qia lebouriae","OtherDescriptors":null,"Notes":null,"AnaPub":2015,"MonPub":null,"DateUpdate":"2016-09-15","DateCreate":"2016-05-29","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000355114900010","VABBcode":null,"OpenAcc":0,"DOI":"10.2216/14-94.1"},"refs":null,"anarec":{"AnaID":257165,"PubliDate":2015,"Pagination":"210-232","XtraPublOfAnaID":null,"ISBN":null,"Volume":"54","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43657,"SerRR":"Phycologia.
