Based on the molecular data for COI, the closest congener differs with 122 base pairs.<h3>Conclusion</h3>Together, the combined morphological and molecular characterisation will provide a foundation for future, taxonomic, phylogenetic and biogeographical studies within the genus <i>Gnathia</i> and the Gnathiidae.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Redescription and molecular characterisation of <i>Gnathia tridens</i> Menzies & Barnard, 1959 (Isopoda: Gnathiidae), a presumed ubiquitous nearshore isopod from the temperate Northern Pacific","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:33:01.246364","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2025-07-03","DateCreate":"2025-07-03","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.1007/s11686-025-01005-2"},"refs":null,"anarec":{"AnaID":409470,"PubliDate":2025,"Pagination":"1-13","XtraPublOfAnaID":null,"ISBN":null,"Volume":"70","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":76478,"SerRR":"Acta Parasitologica.
