Along the Atlantic coast of North America, specimens of <i>Scolelepis</i> inhabiting high-energy beaches have long been erroneously identified as the European species <i>Scolelepis squamata</i> (O.F. Müller, 1806). In this study, we examined specimens of <i>Scolelepis</i> collected from Massachusetts to Virginia, finding they match <i>Scolelepis agilis</i> (Verrill, 1873), originally described from beaches in New Jersey. <i>Scolelepis agilis</i> can be most easily distinguished from <i>S. squamata</i> based on differences in palp ciliary pattern, morphology of neuropodial lamellae, and the quantity and start of both notopodial and neuropodial hooded hooks. Live specimens of <i>S. agilis</i> collected from New York were also examined to provide data on their reproduction and morphometric analyses. In addition, molecular data (18S, 28S rRNA, cytochrome c oxidase I and 16S rRNA) showed that specimens of <i>S. agilis</i> from the north to mid-Atlantic coast formed a monophyletic group (<i>p</i>-distance ≤ 0.004 for MA, RI, NY and VA populations) and were distinct from <i>S. squamata</i> (<i>p</i>-distance ≥ 0.196 (0.03 SE)). The molecular data also suggest the presence of several misidentified or undescribed species of <i>Scolelepis</i>, highlighting the need for additional taxonomic work on the genus from these localities as well as others (e.g. South Africa) where the worms have been incorrectly identified as <i>S. squamata</i>. A key to species of <i>Scolelepis</i> from the east coast of the United States is provided and a lectotype and paralectotypes for <i>S. agilis</i> are herein designated.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Morphological and molecular investigation of <i>Scolelepis agilis</i> (Verrill, 1873) (Annelida: Spionidae) from beaches of the Atlantic coast of North America","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-04-22 01:33:13.880969","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Beach","OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2025-04-15","DateCreate":"2024-12-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.1080/15627020.2024.2373809"},"refs":null,"anarec":{"AnaID":404911,"PubliDate":2025,"Pagination":"94-118","XtraPublOfAnaID":null,"ISBN":null,"Volume":"60","Issue":"1-2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":56693,"SerRR":"African Zoology.
