This genus is distinguished from other genera of the subfamily Parancistrolepidinae with a combination of shell traits, including (1) a low spire, (2) sharp, carinate spiral cords or keels and (3) a long, curved siphonal canal, but not with a difference in radular morphology as suggested by previous authors. Three allopatric or parapatric species are recognized in the upper bathyal (447–2057 m) waters around Japan and Taiwan: <i>B</i>. <i>tokoyodaensis</i> from off Hokkaido to Sagami Bay in the Northwest Pacific, <i>B</i>. <i>trochoidea</i> off Kumano-nada to Miyazaki in the Northwest Pacific and along Nansei Islands in the East China Sea, and <i>B</i>. <i>taiwanensis</i> sp. nov. in the South China Sea. These species bear large paucispiral protoconchs that are indicative of benthic early development without a pelagic larval period, and hence low dispersal capability. Seafloor topography seems to have acted as a barrier for their dispersal; the range of <i>B</i>. <i>tokoyodaensis</i> supports the previous finding that Izu Peninsula delimits westward distribution of bathyal gastropod species of boreal origins.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Systematics and distributions of upper bathyal species in <i>Bathyancistrolepis</i>, a deep-sea whelk genus endemic to the Northwest Pacific (Gastropoda: Buccinidae)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-12 01:32:21.454502","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2023,"MonPub":null,"DateUpdate":"2023-12-11","DateCreate":"2023-12-11","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:001114717800007","VABBcode":null,"OpenAcc":1,"DOI":"10.2108/zs230067"},"refs":null,"anarec":{"AnaID":369415,"PubliDate":2023,"Pagination":"486-496","XtraPublOfAnaID":null,"ISBN":null,"Volume":"40","Issue":"6","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44094,"SerRR":"Zoological Science.
