In this paper I demonstrate that what was previously considered to be a single species, <i>Crepidula aculeata</i>, is an ancient (3-15 Myr) cryptic species complex made up of at least eight species, and that this group should be placed in the genus <i>Bostrycapulus</i>. Despite the difficulty in finding diagnostic adult shell and anatomical features upon which species can be unambiguously identified, DNA sequences, protoconch morphology, embryonic morphology and developmental characters clearly differentiate these eight species. A single species with direct development and nurse eggs is present in the South Atlantic, and a species with planktotrophic development occurs in the equatorial Pacific. The species from Japan, Australia, Florida, the Pacific coasts of Mexico and Central America, and the Cape Verde Islands all have direct development. Most of these species are separated by > 15% divergence in COI sequence data. The fossil record of <i>Bostrycapulus</i> goes back to the Miocene, which agrees with genetic estimates of divergences within the genus ranging from 3 to 15 Mya. Surprisingly, these ancient species differ only slightly in morphology from each other and genetic differentiation does not correlate with geographical distance. I revise the genus <i>Bostrycapulus</i> on the basis of differences in adult morphology, embryonic morphology, mode of development, protoconch morphology, and DNA sequence data. I also describe four new species (<i>B. pritzkeri</i> sp. nov., <i>B. odites</i> sp. nov., <i>B. latebrus</i> sp. nov. and <i>B. urraca</i> sp. nov.) and remove three others (<i>B. gravispinosus, B. calyptraeformis</i>, and <i>B</i>. cf. <i>tegulicius</i>) from synonymy with <i>B. aculeatus</i>.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Development, phylogeny, and taxonomy of <i>Bostrycapulus</i> (Caenogastropoda: Calyptraeidae), an ancient cryptic radiation","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:11.000181","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2005,"MonPub":null,"DateUpdate":"2005-05-30","DateCreate":"2005-05-23","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000229093700005","VABBcode":null,"OpenAcc":1,"DOI":"10.1111/j.1096-3642.2005.00162.x"},"refs":null,"anarec":{"AnaID":72918,"PubliDate":2005,"Pagination":"75-101","XtraPublOfAnaID":null,"ISBN":null,"Volume":"144","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45039,"SerRR":"Zoological Journal of the Linnean Society.
