Although 20 nominal species and subspecies have been described worldwide, most were later synonymized with <i>P. pictus. </i>Here, we provide a commented taxonomic catalogue based on original descriptions and historical literature, highlighting characters of potential diagnostic value and identifying several taxa that warrant re-evaluation. We also describe <i>Polyophthalmus baianus </i><strong>sp. nov.</strong>, from northwestern Brazil, the first species of the genus described from the southwestern Atlantic. The new species is distinguished by the absence of a prostomial palpode, presence of interramal papillae and minute dorsal and ventral cirri throughout the body, distribution of 12–14 pairs of segmental eyespots, and an anal cone bearing six pairs of marginal papillae. COI and 16S genetic distances support the distinctiveness of the new species from other available <i>Polyophthalmus</i> molecular data. Our results reinforce the need to reassess long-standing synonymizations, redescribe available type material, and recollect topotypic specimens to clarify species boundaries and better understand diversification within <i>Polyophthalmus</i>.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A commented catalogue of <i>Polyophthalmus</i> Quatrefages, 1850 (Annelida, Opheliidae) including a new species from Brazil","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-09-01 01:46:38.854188","timezone_type":1,"timezone":"+02:00"},"AuthorKeywords":"polychaetes; opheliids; taxonomic catalogue; northeastern Brazil","OtherDescriptors":null,"Notes":null,"AnaPub":2026,"MonPub":null,"DateUpdate":"2026-08-25","DateCreate":"2026-08-25","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.11646/zootaxa.5873.1.2"},"refs":null,"anarec":{"AnaID":441357,"PubliDate":2026,"Pagination":"32-48","XtraPublOfAnaID":null,"ISBN":null,"Volume":"5873","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":57347,"SerRR":"Zootaxa.
