Previous works have synonymized many of these morphologically similar species with <i>H. durvillei</i>. Our increased taxon sampling and molecular data indicate that the taxonomy of the Indo-Pacific <i>Halymenia</i> species is in need of revision, and that several aspects of taxonomies proposed by previous authors now seem unlikely. Thus, the aim of the present work was to analyse species delimitation in branched <i>Halymenia</i> species. Molecular and morphological data for specimens from the coral triangle and peripheral Indo-Pacific localities (East African coast, Hawaii) were used to understand species delimitation for selected branched <i>Halymenia</i> spp. Phylogenetic analyses based on 29 <i>rbc</i>L gene sequences grouped the specimens in four well-supported clusters at the species level with high p-distances (2.7–5.3%). After the morphological analysis, five features were retained as diagnostic to identify the four species studied. Our analyses led to the recognition and description of two new species, <i>H. hawaiiana</i> from the Hawaiian Islands (previously erroneously called <i>H. formosa</i>) and <i>H. tondoana</i> from the Philippines. In addition, <i>H. harveyana</i> (currently treated as a subspecies of <i>H. floresii</i> in Australia) is reassessed and recognized at the species level. Specimens with seven orders of branching and a thick cortex (70–150?µm) formed a monophyletic group, including sequences from previous work, with mostly well-supported branches and with high p-distances at the species level. We propose to call this group the <i>H. durvillei</i> complex until further reassessment is completed. None of the sequences studied here grouped with <i>H. floresii</i> from the Mediterranean, suggesting that previous Indo-Pacific reports of the species were erroneous.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Branched <i>Halymenia</i> species (Halymeniaceae, Rhodophyta) in the Indo-Pacific region, including descriptions of <i>Halymenia hawaiiana</i> sp. nov. and <i>H. tondoana</i> sp. nov.","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Australia; Halymenia; Halymenia durvillei; Halymenia floresii; Halymeniahawaiiana; Halymenia tondoana; Hawaii; Indo-Pacific; Philippines; rbcL;red algae; Rhodophyta; taxonomy","OtherDescriptors":null,"Notes":null,"AnaPub":2012,"MonPub":null,"DateUpdate":"2015-10-29","DateCreate":"2014-05-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000311784700007","VABBcode":null,"OpenAcc":0,"DOI":"10.1080/09670262.2012.733734"},"refs":null,"anarec":{"AnaID":238595,"PubliDate":2012,"Pagination":"421-432","XtraPublOfAnaID":null,"ISBN":null,"Volume":"47","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42675,"SerRR":"European Journal of Phycology.
