The new species belongs to a large group of Spionidae comprising the <i>Polydora</i> complex (ca. 178 species) having a modified setiger 5. The new species, <i>Dipolydora walkerae</i> <strong>sp. nov.</strong>, belongs to a small group of <i>Dipolydora </i>having large hooked spines on setiger 5 surmounted with a crest or cloak of fine bristles or fibrils and has posterior notopodia with modified acicular spines. The majority of polydorins are from intertidal or continental shelf depths; deep-water accounts are few and poorly documented. The new species is compared with its closest congener, <i>Dipolydora armata</i>. Previous accounts of shell-boring polydorins from offshore are tabulated by the depth of occurrence and discussed. The new species represents the deepest confirmed record for a shell-boring spionid polychaete.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A new species of <i>Dipolydora</i> (Annelida, Spionidae) from deep-water methane seep habitats off Louisiana (Gulf of Mexico), a borer in shells of the gastropod <i>Kanoia meroglypta</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-10-02 01:33:08.230580","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Deep-sea, shell borer, polychaete","OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2025-09-25","DateCreate":"2025-09-25","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.11646/zootaxa.5679.1.3"},"refs":null,"anarec":{"AnaID":418584,"PubliDate":2025,"Pagination":"74-82","XtraPublOfAnaID":null,"ISBN":null,"Volume":"5679","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":57347,"SerRR":"Zootaxa.
