We used DNA-based species delimitation approaches, phylogenetic, and historical biogeographical analyses to uncover cryptic diversity and infer the drivers of biogeographic patterns. We delimited 43 species in <i>Pterocladiella</i>, of which 19 are undescribed. Our multigene time-calibrated phylogeny and ancestral area reconstruction indicated that <i>Pterocladiella</i> most likely originated during the Early Cretaceous in the Tethys Sea. Ancient Tethyan vicariance and long-distance dispersal have shaped current distribution patterns. The ancestor of Eastern Pacific species likely arose before the formation of the formidable Eastern Pacific Barrier—a first confirmation using molecular data in red algae. Divergences of Northeast and Southeast Pacific species have been driven by the Central American Seaway barrier, which, paradoxically, served as a dispersal pathway for Atlantic species. Both long- and short-distance dispersal scenarios are supported by genetic relationships within cosmopolitan species based on haplotype analysis. Asymmetrical distributions and the predominance of peripatry and sympatry between sister species suggest the importance of budding speciation in <i>Pterocladiella</i>. Our study highlights the underestimation of global diversity in these crucial components of coastal ecosystems and provides evidence for the complex evolution of current species distributions.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Ancient Tethyan vicariance and long-distance dispersal drive global diversification and cryptic speciation in the red seaweed <i>Pterocladiella</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-19 01:32:19.377436","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"biogeography; Eastern Pacific Barrier; Gelidiales; molecular dating; overlooked biodiversity; sister species; Tethyan origin","OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2023-03-09","DateCreate":"2023-03-08","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000812087700001","VABBcode":null,"OpenAcc":1,"DOI":"10.3389/fpls.2022.849476"},"refs":null,"anarec":{"AnaID":361915,"PubliDate":2022,"Pagination":"849476","XtraPublOfAnaID":null,"ISBN":null,"Volume":"13","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":258967,"SerRR":"Frontiers in Plant Science.
