However, in the last years, the latter was removed from Cyamiocardium, alternatively being placed into Perrierina. All these species were mainly based on the general shell morphology of a reduced number of specimens, with scarce (or no) information on their anatomy and reproductive traits. The present study provides the first systematic revision of the species of Cyamiocardium occurring in sub-Antarctic and Antarctic waters. For that, an extant source of material was available; and several characters not studied (in detail) before, such as prodissoconch morphology and microsculpture, gross anatomy, and reproductive characteristics, were investigated. As part of this study, the identity of C. denticulatum (the type species of the genus) and that of C. dahli are clarified. In addition, C. rotundatum is revalidated as a full species, and C. crassilabrum is transferred again to Cyamiocardium. Furthermore, three new species were detected and are described herein: Cyamiocardium chuanisinense new species, Cyamiocardium namuncurense new species, and Cyamiocardium yeskumaala new species. The new information arising from this study is used to redefine the genus Cyamiocardium, and to re-analyze the similarities/differences of this genus with other cyamiids.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The genus Cyamiocardium Soot-Ryen, 1951 (Bivalvia: Cyamiidae) in sub-Antarctic and Antarctic waters","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:43.331226","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Southern Ocean; Pampa Azul","OtherDescriptors":null,"Notes":null,"AnaPub":2018,"MonPub":null,"DateUpdate":"2018-07-12","DateCreate":"2018-02-15","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000434253800009","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s00300-018-2275-8"},"refs":null,"anarec":{"AnaID":292772,"PubliDate":2018,"Pagination":"1157-1174","XtraPublOfAnaID":null,"ISBN":null,"Volume":"41","Issue":"6","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43637,"SerRR":"Polar Biology.
