Consequently, resolving cryptic diversity in <i>Newhousia</i> requires molecular phylogenetics. Bayesian and maximum likelihood phylogenetic trees, based on the concatenated <i>cox</i>1, <i>cox</i>3, <i>psb</i>A, <i>rbc</i>L and 18S rDNA sequences, supported a sister relationship of <i>Newhousia</i> with <i>Lobophora</i>/<i>Zonaria</i> clade. Analyses revealed five distinct evolutionary lineages within <i>Newhousia</i>. Genetic variation between the lineage from Guam and the two hitherto known <i>Newhousia</i> species, <i>N. imbricata</i> from Hawaii and <i>N. yagha</i> from Papua New Guinea, warrant the description of one new species, <i>N. sumayensis sp. nov</i>. The other two lineages, from the Society Islands and Vanuatu, were identified as geographically distinct populations of <i>N. imbricata</i> with limited genetic variation, rather than independent species. In the Society Islands, <i>N. imbricata</i> is common between depths of 10 m and 20 m as unattached spherical structures, or attached to hard substrate. In Guam, <i>N. sumayensis sp. nov</i>. grows abundantly in sciophilous habitats at depths of 10–21 m. We provide the first documentation of spores for this genus and of structures resembling plurilocular antheridia. Increased sampling throughout the Indo-Pacific region is required to further elucidate the distribution range and patterns of species richness in <i>Newhousia</i>.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Phylogenetic position of <i>Newhousia</i> (Dictyotales, Phaeophyceae) and the description of <i>N. sumayensis sp. nov</i>. from Guam","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":"Mariana Islands; Marine biodiversity; Molecular phylogeny; Society Islands","OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2023-11-27","DateCreate":"2023-11-27","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000779546500001","VABBcode":null,"OpenAcc":0,"DOI":"10.1080/00318884.2022.2034364"},"refs":null,"anarec":{"AnaID":369115,"PubliDate":2022,"Pagination":"255-264","XtraPublOfAnaID":null,"ISBN":null,"Volume":"61","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43657,"SerRR":"Phycologia.
