Different <i>Spiniferites</i> species have been connected to a single <i>Gonyaulax</i> species, raising the question of whether they are over-classified. Through germination experiments of cysts with the morphological features of four species of <i>Spiniferites</i>, viz. <i>S. bentorii, S. hyperacanthus, S. ramosus</i> and <i>S. scabratus</i>, we established cyst-theca relationships. Cysts with the morphology of <i>S. bentorii</i> gave rise to vegetative, motile cells of <i>Gonyaulax nezaniae sp. nov</i>., which is characterized by two stout antapical spines. Cysts with <i>S. hyperacanthus</i> and <i>S. ramosus</i> morphologies germinated into <i>Gonyaulax whaseongensis</i> and <i>G. spinifera</i>, respectively. Cysts with <i>S. scabratus</i> morphology lacked a ventral pore and were attributed to <i>Gonyaulax</i> cf. <i>spinifera</i>. Gene sequences for SSU, LSU and/or ITS-5.8S rRNA were obtained from these four species, and from cysts with the morphology of <i>Spiniferites belerius, S. mirabilis, S. lazus, Spiniferites</i> cf. <i>bentorii</i> and <i>Tectatodinium pellitum</i>. The maximum likelihood and Bayesian inference analyses based on LSU and SSU rRNA gene sequences revealed that cysts assignable to <i>Spiniferites</i> formed a polyphyletic group, intermingled with <i>Tectatodinium, Bitectatodinium, Ataxiodinium</i> and <i>Impagidinium</i>, whereas <i>Gonyaulax</i> species appeared as monophyletic. From our results we inferred the phylogenetic positions of <i>S. bentorii, S. mirabilis, S. lazus, S. scabratus, Tectatodinium pellitum</i> and <i>Gonyaulax digitale</i> for the first time, supporting the idea that <i>Spiniferites</i> species are not over-classified and each of them may correspond to different <i>Gonyaulax</i> species.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Cyst-theca relationships of <i>Spiniferites bentorii, S. hyperacanthus, S. ramosus, S. scabratus</i> and molecular phylogenetics of <i>Spiniferites</i> and <i>Tectatodinium</i> (Gonyaulacales, Dinophyceae)","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":"Dinoflagellates; Gonyaulax nezaniae; Gonyaulax spinifera","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2023-05-22","DateCreate":"2023-03-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000670834200001","VABBcode":null,"OpenAcc":0,"DOI":"10.1080/00318884.2021.1930796"},"refs":null,"anarec":{"AnaID":362312,"PubliDate":2021,"Pagination":"332-353","XtraPublOfAnaID":null,"ISBN":null,"Volume":"60","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43657,"SerRR":"Phycologia.
