This study aims to disentangle this complex, elucidating how many species are indeed present in the western Atlantic, and whether <i>M. nigrocincta</i> is different from <i>M. modesta</i>. The mitochondrial markers COI and 16S were congruent in splitting the complex into six lineages: one belonging to <i>M. nigrocincta</i> (mainly from eastern United States), other two lineages related to <i>M.</i> cf. <i>modesta</i> (one from Florida, USA, and the second from Colombia), and three undescribed species from Brazil. Intra- and interspecific genetic distances, respectively, vary from 0–2.7%/6.3–13.5% (COI). The nuclear gene 28S was conservative to separate <i>Marshallora</i> sp. A (Brazil) from <i>M.</i> cf. <i>modesta</i> 2, but recognized <i>M.</i> cf. <i>modesta</i> 1, <i>M. nigrocincta</i>, and <i>Marshallora</i> sp. B (Brazil). The shell morphology is highly variable, but the presence of three basal cords seems to occur only in <i>M. nigrocincta</i>. The radular morphology exhibits a wide variation in the number of cusps of the central and lateral teeth. The new species herein identified will require formal descriptions following further fieldwork efforts, since the selected voucher material was lost during a fire. New generic allocations are made to <i>Marshallora amicorum</i> comb. nov., <i>Marshallora pusilla</i> comb. nov., and <i>Marshallora medinae</i> comb. nov., which is regarded as <i>nomen dubium</i>. This study may stimulate the incorporation of DNA analysis in the systematics of Triphoroidea, improving the knowledge about its biodiversity.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Cryptic speciation in the “<i>Marshallora nigrocincta</i>” species complex (Gastropoda, Triphoridae) from the Western Atlantic","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-06 01:34:33.990863","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"biodiversity, DNA, marine gastropods, systematics, Triphoroidea","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2021-07-09","DateCreate":"2021-07-08","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000621643300001","VABBcode":null,"OpenAcc":0,"DOI":"10.1111/jzs.12461"},"refs":null,"anarec":{"AnaID":339872,"PubliDate":2021,"Pagination":"819-838","XtraPublOfAnaID":null,"ISBN":null,"Volume":"59","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":236648,"SerRR":"Journal of Zoological Systematics and Evolutionary Research.
