To bridge this gap, we compared historical assessments of <i>Ulva</i> sensu lato diversity in the Netherlands and Belgium with molecular-based identifications. By combining DNA barcoding of recent field collections with NGS data from historical herbarium voucher specimens, we confirmed the presence of 17 <i>Ulva</i> species using <i>tufA</i> barcoding, including three unidentified clades. Additionally, we identified <i>Blidingia marginata</i>, <i>B.&nbsp;minima</i>, <i>Monostroma grevillei</i>, <i>Umbraulva dangeardii</i>, and a taxonomic entity that matched reference sequences of both <i>Gayralia oxysperma</i> and <i>Kornmannia leptoderma</i>. Of the 24 species previously reported in the southern North Sea based on published literature, only 13 species were molecularly confirmed, highlighting the substantial discrepancy between traditional and DNA-based species identifications in this group of algae. Integrating historical herbarium vouchers into our biodiversity assessment revealed that this mismatch was largely due to misinterpretation of names and to a lesser extent changing species concepts. Plastid genome and nuclear ribosomal DNA assemblies of <i>Ulva intestinaloides</i> and <i>U.&nbsp;pseudolinza</i> type material showed that their ITS, <i>rbcL</i>, and <i>tufA</i> sequences were identical or highly similar to reference sequences of <i>U.&nbsp;compressa</i> and <i>U.&nbsp;intestinalis</i>, respectively, indicating that they are synonyms of these species. Finally, we report four new species records for the southern North Sea: <i>Ulva capillata</i> and <i>Umbraulva dangeardii</i> that are native to the Northeast Atlantic, and the non-indigenous <i>Ulva californica</i> and <i>U.&nbsp;shanxiensis.</i> The latter is a freshwater species that has not been recorded outside China until now. The discovery of unidentified clades and non-native species in the southern North Sea emphasizes the importance of molecular monitoring in uncovering cryptic diversity and improving our understanding of <i>Ulva</i> biodiversity.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Incorporating historic specimens to reassess <i>Ulva</i> diversity in the Netherlands and Belgium","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-01-14 01:32:43.632899","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"DNA barcoding; historical vouchers","OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2026-01-07","DateCreate":"2026-01-07","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:001590543900001","VABBcode":null,"OpenAcc":0,"DOI":"10.1002/tax.70058"},"refs":null,"anarec":{"AnaID":436965,"PubliDate":2025,"Pagination":"1314-1334","XtraPublOfAnaID":null,"ISBN":null,"Volume":"74","Issue":"6","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43954,"SerRR":"Taxon.
