The discovery of nine distinct morphotypes of <i>Oscarella</i> co-existing in cryptic habitats in south-east Brazil represents a taxonomic puzzle that requires an integrative taxonomic approach for species delimitation. Here we combined genetic (<i>cox-1</i> and <i>cob</i> genes), morphological, anatomical, cytological, microbiological, reproductive and ecological datasets to delimit and describe three new species of <i>Oscarella</i>, one of which is highly polymorphic. <i>Oscarella aurantia</i>, sp. nov. is orange, microlobate, with metachromatic vacuolar cells, granular cells, and microgranular cells. <i>Oscarella carollineae</i>, sp. nov. is intertidal, cream or red, microlobate, with granulo-vacuolar cells, dense globular cells, and granular cells. <i>Oscarella ruthae</i>, sp. nov. is highly polymorphic, with tubular or papillate lobes; colour violet, pink, purple, red, orange or cream, often with shades of cream or green at the base; abundant clusters of vacuolar cells type 1, and rare vacuolar cells type 2 and microgranular cells. No single character was sufficient for species delimitation due to high intraspecific variation. Integration of multiple datasets was essential to delimit species of <i>Oscarella</i> and would also be helpful for the taxonomy of other polymorphic sponges.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Solving a taxonomic puzzle: integrative taxonomy reveals new cryptic and polymorphic species of <i>Oscarella</i> in south-eastern Brazil (Homoscleromorpha : Oscarellidae)","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":"biodiversity, biology, Brazil, Homosclerophorida, Porifera, species delimitation, systematics, Tropical Southwestern Atlantic","OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2023-08-28","DateCreate":"2023-03-06","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000841722600001","VABBcode":null,"OpenAcc":0,"DOI":"10.1071/IS21056"},"refs":null,"anarec":{"AnaID":361742,"PubliDate":2022,"Pagination":"714-750","XtraPublOfAnaID":null,"ISBN":null,"Volume":"36","Issue":"8","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":105591,"SerRR":"Invertebrate Systematics.
