Currently, 37 valid species belong to this genus and only three of them are found in the Southern Ocean, namely <i>T. challengeriana</i> Bergh, 1884, <i>T. dantarti</i> Ballesteros & Avila, 2006, and <i>T. vorax</i> (Odhner, 1926). In this study, we shed light on the long-term discussed systematics and taxonomy of Antarctic <i>Tritonia</i> species using morpho-anatomical and molecular techniques. Samples from the Weddell Sea and Bouvet Island were dissected and prepared for scanning electron microscopy. The three molecular markers COI, 16S, and H3 were sequenced and analysed through maximum-likelihood and Bayesian methods. The phylogenetic analyses and species delimitation tests clearly distinguished two species, <i>T. challengeriana</i> widely spread in the Southern Ocean and <i>T. dantarti</i> endemic to Bouvet Island<i>.</i> Colouration seems to be an unreliable character to differentiate among species since molecular data revealed both species can either have orange or white colour morphotypes. This variability could be explained by pigment sequestration from the soft coral species they feed on. Morphological analyses reveal differences between Antarctic and Magellanic specimens of <i>T. challengeriana.</i> However, the relationship between <i>T. challengeriana</i> specimens from these two regions remains still unclear due to the lack of molecular data. Therefore, the validity of the <i>T. antarctica</i> Martens & Pfeffer, 1886, exclusively found in Antarctic waters requires further systematic work.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Orange is the new white: taxonomic revision of <i>Tritonia</i> species (Gastropoda: Nudibranchia) from the Weddell Sea and Bouvet Island","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-13 01:31:50.168638","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Phylogenetic analyses, Southern Ocean, Species delimitation tests, Tritoniidae taxonomy","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2021-07-05","DateCreate":"2021-07-02","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000620456900003","VABBcode":null,"OpenAcc":1,"DOI":"10.1007/s00300-021-02813-8"},"refs":null,"anarec":{"AnaID":339546,"PubliDate":2021,"Pagination":"559-573","XtraPublOfAnaID":null,"ISBN":null,"Volume":"44","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43637,"SerRR":"Polar Biology.
