These sequences closely matched those reported from adult specimens from Colorado and Oregon, as well as larval infections in humans and a captive orangutan. We describe here a new species from British Columbia and Alberta (Canada), <jats:italic>Versteria rafei<\/jats:italic> n. sp., based upon morphological diagnostic characteristics and genetic distance and phylogeny. <jats:italic>Versteria rafei<\/jats:italic> n. sp. differs from the three other described species of the genus in the smaller scolex and cirrus sac. It also differs from <jats:italic>V. mustelae<\/jats:italic> (Eurasia) and <jats:italic>V. cuja<\/jats:italic> (South America) by having an armed cirrus, which is covered in hair-like bristles, and in the shape of its hooks, with a long thorn-like blade, and short or long handle (<jats:italic>vs.<\/jats:italic> a short sharply curved blade and no difference in handle size in previously described species). The poorly known <jats:italic>V. brachyacantha<\/jats:italic> (Central Africa) also has an armed cirrus and similarly shaped hooks. However, it differs from the new species in the number and size of hooks. Phylogenetic analysis of the <jats:italic>cox1<\/jats:italic> and <jats:italic>nad1<\/jats:italic> mitochondrial regions showed that our specimens clustered with isolates from undescribed adults and larval infections in North America, and separate from <jats:italic>V. cuja<\/jats:italic>, confirming them to be a distinct species from the American Clade.<\/jats:p>","DOI":"10.1017\/s0022149x23000895","type":"journal-article","created":{"date-parts":[[2024,1,3]],"date-time":"2024-01-03T07:51:37Z","timestamp":1704268297000},"source":"Crossref","is-referenced-by-count":4,"title":["A new species of <i>Versteria<\/i> (Cestoda: Taeniidae) parasitizing <i>Neogale vison<\/i> and <i>Lontra canadensis<\/i> (Carnivora: Mustelidae) from Western Canada"],"prefix":"10.1017","volume":"98","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5763-5128","authenticated-orcid":false,"given":"K.M.","family":"Shanebeck","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1037-894X","authenticated-orcid":false,"given":"J.","family":"Bennett","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4705-7859","authenticated-orcid":false,"given":"S.J.","family":"Green","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3347-6497","authenticated-orcid":false,"given":"C.","family":"Lagrue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0950-7767","authenticated-orcid":false,"given":"B.","family":"Presswell","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2024,1,3]]},"reference":[{"key":"S0022149X23000895_r33","doi-asserted-by":"publisher","DOI":"10.1038\/nmeth.2089"},{"key":"S0022149X23000895_r42","doi-asserted-by":"publisher","DOI":"10.14430\/arctic1238"},{"key":"S0022149X23000895_r18","doi-asserted-by":"publisher","DOI":"10.1093\/molbev\/msy096"},{"key":"S0022149X23000895_r12","doi-asserted-by":"publisher","DOI":"10.1645\/0022-3395(2000)086[0089:APHFSO]2.0.CO;2"},{"key":"S0022149X23000895_r41","doi-asserted-by":"crossref","first-page":"129","DOI":"10.5962\/bhl.part.75850","article-title":"Etude parasito-\u00e9cologique des petits Mammif\u00e8res (Insectivores et Rongeurs) du val de l\u2019Allondon (Gen\u00e8ve)","volume":"74","author":"Wahl","year":"1967","journal-title":"Revue suisse de zoologie"},{"key":"S0022149X23000895_r3","first-page":"68","article-title":"A new species of Versteria (Cestoda: Taeniidae) parasitizing Galictis cuja (Carnivora: Mustelidae) from Patagonia, Argentina: morphological and molecular characterization","volume":"19","author":"Bagnato","year":"2022","journal-title":"International Journal of Parasitology: Parasites and Wildlife"},{"key":"S0022149X23000895_r20","first-page":"1","volume-title":"Mustela vison","volume":"608","author":"Larivi\u00e8re","year":"1999"},{"key":"S0022149X23000895_r32","first-page":"406","article-title":"The neighbor-joining method: a new method for reconstructing phylogenetic trees","volume":"4","author":"Saitou","year":"1987","journal-title":"Molecular Biology and Evolution"},{"key":"S0022149X23000895_r2","first-page":"59","article-title":"Cestodes nouveaux du Congo Belge","volume":"8","author":"Baer","year":"1951","journal-title":"Acta Tropica"},{"key":"S0022149X23000895_r7","first-page":"342","article-title":"Wildlife-transmitted Taenia and Versteria cysticercosis and coenurosis in humans and other primates","volume":"9","author":"Deplazes","year":"2019","journal-title":"International Journal of Parasitology: Parasites and Wildlife"},{"key":"S0022149X23000895_r11","doi-asserted-by":"publisher","DOI":"10.3201\/eid2001.131191"},{"key":"S0022149X23000895_r40","first-page":"3","article-title":"A taxonomic revision of the Genus Taenia Linnaeus, 1758, S.
