Here, we established nine strains of <i>G. verior</i> by germinating cysts or isolating cells from localities from the European Atlantic to the Caspian Sea and the Pacific Ocean. Both cyst and thecal morphology were examined by light and scanning electron microscopy. SSU, LSU and/or ITS-5.8S rRNA gene sequences were obtained from all strains. Cells of <i>G. verior</i> have a plate formula of Po, 4′, 2a, 6-7′′, 6C, 6S, 6′′′, 1p, 1′′′′ with an L-type ventral organisation, characterised by two either straight or curved antapical horns of variable length. Cysts of <i>G. verior</i> are oval, smooth and contain one or two yellow accumulation bodies. The maximum-likelihood and Bayesian inference analyses based on SSU and LSU rRNA gene sequences revealed two clades of <i>G. verior</i>, referred to as ribotypes A and B. Genetic distances based on ITS-5.8S rRNA gene sequences within the same ribotype were less than 0.06, but greater than 0.32 between ribotypes. <i>G. verior</i> is reclassified as <i>Sourniaea diacantha gen. et comb. nov</i>., which is attributed to Lingulodiniaceae together with <i>Pyxidinopsis, Lingulodinium</i> and <i>Amylax</i>. Our results suggest that Lingulodiniaceae can be separated from Protoceratiaceae and Gonyaulacaceae based on ventral organisation, apical complex, ventral pore and number of anterior intercalary plates. One strain of <i>S. diacantha</i> was examined for yessotoxin production by LC-MS/MS but did not produce toxin.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Reclassification of <i>Gonyaulax verior</i> (Gonyaulacales, Dinophyceae) as <i>Sourniaea diacantha</i> gen. et comb. 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":"Amylax diacantha; Cysts; Dinoflagellate; Gonyaulax longispina; Molecular phylogeny","OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2022-10-07","DateCreate":"2022-02-09","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000525263100001","VABBcode":null,"OpenAcc":0,"DOI":"10.1080/00318884.2020.1735926"},"refs":null,"anarec":{"AnaID":349591,"PubliDate":2020,"Pagination":"246-260","XtraPublOfAnaID":null,"ISBN":null,"Volume":"59","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43657,"SerRR":"Phycologia.
