Most of the species remain known only from shell morphology, which has proved to be extremely variable in the group. Few studies have addressed their anatomy and biology, and no studies have combined morphological, anatomical and biological characters with molecular characters. This has led to the hiatellids all around the world being regarded as a single, widely distributed species. This contribution represents a step towards a better understanding of hiatellids worldwide by providing the first integrative study of the species occurring in southern South America. Three entities are recognized: <em>Hiatella meridionalis</em>, <em>Hiatella barnea</em> and <em>Hiatella umbonata</em> sp. nov. To understand their intraspecific variability, all the species are carefully described and figured, based on large series of specimens. <em>Saxicava chilensis</em>, <em>Saxicava mollis</em>, <em>Saxicava lebruni</em> and <em>Saxicava subantarctica</em> are considered synonyms of <em>H. meridionalis</em>; a lectotype for <em>S. subantarctica</em> is designated; and <em>S. antarctica</em> and <em>S. frigida</em> are regarded as <em>nomina dubia</em>. This study suggests that worldwide living hiatellids might have originated from South American species and that reduction/loss of hinge teeth during ontogeny and life on hard substrates or on/inside other invertebrates would represent derived traits within the genus <em>Hiatella</em>.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Decrypting the feared genus <i>Hiatella</i> (Bivalvia): South American species","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-03 01:32:10.414910","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Adapedonta, AMP Namuncurá/Banco Burdwood, Euheterodonta, Mollusca, Patagonia","OtherDescriptors":null,"Notes":null,"AnaPub":2023,"MonPub":null,"DateUpdate":"2023-11-27","DateCreate":"2023-11-27","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:001083331300001","VABBcode":null,"OpenAcc":0,"DOI":"10.1093/zoolinnean/zlad064"},"refs":null,"anarec":{"AnaID":369168,"PubliDate":2023,"Pagination":"882-905","XtraPublOfAnaID":null,"ISBN":null,"Volume":"199","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45039,"SerRR":"Zoological Journal of the Linnean Society.
