Whether the soft-shell clam is a single species with a circumboreal range or a species complex also comprising <i>Mya japonica</i> Jay, 1857 distributed in the north Pacific has long been debated by malacologists and palaeontologists based on slight differences in shell morphology. We used an integrative taxonomic approach incorporating available <i>Mya</i> spp. mitochondrial <i>COI</i> and 16S rRNA, and nuclear 28S rRNA gene sequences, as well as spermatozoan and shell morphological characters to test the validity of <i>M. japonica</i> and examine the range of soft-shell clam distribution. Although differences in shell morphology were minor, the results from tree topologies, pairwise uncorrected <i>p</i>-distances, Automatic Barcode Gap Discovery (ABGD) and spermatozoan ultramorphological data confirm the validity of <i>M. japonica</i> in both its endemic region in the northwest Pacific, and as here newly reported introduced populations in British Columbia in the northeast Pacific, and show that <i>M. arenaria</i> is distributed in the northeast Pacific, North Atlantic, Barents Sea (Arctic Ocean) and Mediterranean. We estimate these two closely related sister species diverged 4.1–12.5 Myr during early Pliocene to late Miocene, which is consistent with current evolutionary theory regarding <i>M. arenaria</i>. In addition, ABGD indicated the congener <i>Mya truncata</i> Linnaeus, 1758 may represent a species complex, but additional evidence is still needed to clarify its taxonomic status.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A tale of two soft-shell clams: an integrative taxonomic analysis confirms <i>Mya japonica</i> as a valid species distinct from <i>Mya arenaria</i> (Bivalvia: Myidae)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-13 01:31:34.448575","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2018,"MonPub":null,"DateUpdate":"2019-02-27","DateCreate":"2018-01-23","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000456079100002","VABBcode":null,"OpenAcc":0,"DOI":"10.1093/zoolinnean/zlx107"},"refs":null,"anarec":{"AnaID":292128,"PubliDate":2018,"Pagination":"605-622","XtraPublOfAnaID":null,"ISBN":null,"Volume":"184","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45039,"SerRR":"Zoological Journal of the Linnean Society.
