The material studied was collected at depths ranging from 3 to 30 m at latitudes comprised between 42° and 49°S. Both species share the same habitat and show a morphological plasticity, but differ in their colour. <i>Halisarca magellanica </i>is bright pink to whitish with three morphs whereas <i>H. desqueyrouxae </i>sp. nov. is light brown to beige with two morphs. An extensive investigation in TEM and SEM reveals several differences among cell types with inclusions between both species. Three distinct spherulous cells occur. Type 1 is shared by both species, Type 2 is occasional in <i>H. magellanica</i> but absent from <i>H.</i> <i>desqueyrouxae</i> sp. nov. Type 3 is rare in <i>H. magellanica </i>and occurs abundantly in half of the specimens of <i>H. desqueyrouxae</i> sp. nov. Granular cells are shared by both species but do not occur in all specimens. Microgranular cells are characteristic of <i>H. magellanica.</i> Both species also clearly differ by their endobiotic bacteria. Phylogenetic analysis of <i>cox1</i> sequences places <i>H. magellanica </i>as a sister group to all other previously published <i>Halisarca </i>species sequences (9.1–9.7% difference) except <i>H. harmelini</i>, while <i>H. desqueyrouxae</i> sp. nov. is placed as a sister group to <i>H. dujardini</i> (2.3% difference).","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Integrative taxonomic re-description of <i>Halisarca magellanica</i> and description of a new species of <i>Halisarca</i> (Porifera, Demospongiae) from Chilean Patagonia","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":"Porifera, Chilean Patagonia, Chondrillida, cytology, Halisarcidae, new species, SEM, TEM, ultrastructure, Verongiomorpha","OtherDescriptors":null,"Notes":null,"AnaPub":2016,"MonPub":null,"DateUpdate":"2017-03-26","DateCreate":"2017-03-07","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000390102900001","VABBcode":null,"OpenAcc":0,"DOI":"10.11646/zootaxa.4208.6.1"},"refs":null,"anarec":{"AnaID":283744,"PubliDate":2016,"Pagination":"501-533","XtraPublOfAnaID":null,"ISBN":null,"Volume":"4208","Issue":"6","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":57347,"SerRR":"Zootaxa.
