Species of this family are characterized by high morphological variability, which has caused many taxonomical debates, mainly for the species of the genera <i>Eleutheria</i> Quatrefages, 1842 and <i>Staurocladia </i>Hartlaub, 1917. Herein, we describe <i>Staurocladia dzilamensis</i> sp.&nbsp;nov., a new species of crawling hydromedusa from the southern Gulf of Mexico. This finding also constitutes the first record of the genus <i>Staurocladia</i> for the Gulf of Mexico. The presence of additional nematocyst clusters, supplementing the apical one on the upper branch of the tentacles, places it within <i>Staurocladia</i>. The presence of exumbrellar buds, a conspicuous marginal ring of nematocysts, 6–11 bifid tentacles with lower branches longer than their upper counterpart, the cnidome with stenoteles of two size classes, and two nematocyst clusters on the upper branch supplementing the apical one, opposite placed alternately on its aboral and oral sides permits to differentiate <i>S. dzilamensis</i> from its congeners. A taxonomic key for the species of <i>Staurocladia</i> is provided.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"First record of the genus <i>Staurocladia</i> (Hydrozoa: Cladonematidae) in the Gulf of Mexico with the description of <i>Staurocladia dzilamensis</i> sp. nov., a new species of crawling hydromedusa","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-21 01:33:33.413418","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2024,"MonPub":null,"DateUpdate":"2024-04-02","DateCreate":"2024-04-02","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.5852/ejt.2024.921.2433"},"refs":null,"anarec":{"AnaID":391655,"PubliDate":2024,"Pagination":null,"XtraPublOfAnaID":null,"ISBN":null,"Volume":"921","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":215336,"SerRR":"European Journal of Taxonomy.
