Despite the widespread presence of these genera in the region, few species have been studied at a molecular level. Using partial cytochrome oxidase I (<i>cox1</i>) gene sequences, we analyzed the genetic relationships of four <i>Callistochiton</i> and four <i>Stenoplax</i> species (including Caribbean species), along with two putative new species. Each genus was analyzed separately. The Bayesian Inference (BI) and neighbor-joining analyses recovered two main clades in both genera and support the existence of two new species. <i>Stenoplax quetzalcoatli</i> sp. nov. was recovered sister to <i>Stenoplax petaloides</i> Gould, 1846 and this clade was recovered sisters to <i>Stenoplax mariposa</i> (Dall, 1919). <i>Stenoplax limaciformis</i> (Sowerby in Broderip and Sowerby, 1832) was recovered sister to <i>Stenoplax purpurascens</i> C.B. Adams, 1845 and both nested with <i>Stenoplax floridana</i> Pilsbry, 1892. <i>Callistochiton guerreroensis</i> sp. nov. and <i>Callistochiton</i> cf. <i>expressus</i> are sister species of <i>Callistochiton colimensis</i> (A.G. Smith, 1961). In addition, to solve the identity of two new taxa, we inspected various morphological characters using scanning electron microscopy (SEM). We identified differences between <i>Stenoplax quetzalcoatli</i> sp. nov. and species of the <i>Stenoplax rugulata</i> (Sowerby, 1832) complex characterized by small size and irregular sculpturing. Moreover, <i>Callistochiton guerreroensis</i> sp. nov. differs from <i>Callistochiton expressuss</i> (Carpenter, 1865) by a higher number of ribs in the head valve, minor lateral teeth with a bilobed blade directed inwards, and dorsal girdle scales with rounded spherules.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"DNA barcoding of the intertidal chitons of the genera <i>Stenoplax</i> Dall, 1879 and <i>Callistochiton</i> Carpenter in Dall, 1879 from the Mexican Tropical Pacific with the description of two new species","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-09 01:32:32.240402","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"cox1; genetic relationships; Mollusca; Polyplacophora; taxonomy","OtherDescriptors":null,"Notes":null,"AnaPub":2023,"MonPub":null,"DateUpdate":"2023-05-23","DateCreate":"2023-04-04","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000918224000001","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s12526-022-01308-x"},"refs":null,"anarec":{"AnaID":363144,"PubliDate":2023,"Pagination":"10","XtraPublOfAnaID":null,"ISBN":null,"Volume":"53","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":141757,"SerRR":"Marine Biodiversity.
