Currently, <jats:italic>T<\/jats:italic>. <jats:italic>mahanadicus<\/jats:italic> is synonymized with <jats:italic>Tor putitora<\/jats:italic>, solely based on partial molecular data despite significant morphological differences. In this study, we performed an integrated morphological and molecular analysis to redescribe <jats:italic>T<\/jats:italic>. <jats:italic>mahanadicus<\/jats:italic> from the Mahanadi River. <jats:italic>Tor mahanadicus<\/jats:italic> is distinguished from all known Indian <jats:italic>Tor<\/jats:italic> species by the presence of 2 complete rows of scales between pelvic fin origin and lateral line, small eye (15.3\u201316.9% in head length), and a wide mouth gap (21.7\u201323.8% in head length). Moreover, it undoubtedly distinguished from the closely related species <jats:italic>Tor putitora<\/jats:italic> by having a wider body depth (26.8\u201328.2% in standard length vs. 14.5\u201319.9%), short snout length (23.3\u201326.4% in head length vs. 28.0\u201329.3%) and wide inter orbit space (30.5\u201337.3% in head length vs. 27.6\u201328.5%). Additionally, the molecular phylogenetic tree generated from a combination of three genes demonstrates a monophyletic clade separate from the <jats:italic>Tor putitora<\/jats:italic> clade. Based on the distinct morphological traits and mitochondrial gene sequences, we established <jats:italic>Tor mahanadicus<\/jats:italic> as separate species under the genus <jats:italic>Tor<\/jats:italic>.<\/jats:p>","DOI":"10.1371\/journal.pone.0291436","type":"journal-article","created":{"date-parts":[[2023,9,12]],"date-time":"2023-09-12T17:28:44Z","timestamp":1694539724000},"page":"e0291436","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":5,"title":["Redescription of an endemic mahseer, Tor mahanadicus (David, 1953) from Mahanadi River basin, India based on integrated morphological and molecular techniques"],"prefix":"10.1371","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6089-6182","authenticated-orcid":true,"given":"Jeyaraj Antony","family":"Johnson","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Prasanta","family":"Nanda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bhawana","family":"Pant","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sneha Shivaji","family":"Mane","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vishnupriya","family":"Kolipakam","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2023,9,12]]},"reference":[{"key":"pone.0291436.ref001","doi-asserted-by":"crossref","first-page":"417","DOI":"10.1007\/s11160-019-09566-y","article-title":"Mahseer (Tor spp.) fishes of the world: status, challenges and opportunities for conservation.","volume":"29","author":"AC Pinder","year":"2019","journal-title":"Rev Fish Biol Fisheries"},{"issue":"3","key":"pone.0291436.ref002","doi-asserted-by":"crossref","first-page":"171","DOI":"10.1080\/23308249.2016.1251391","article-title":"Disentangling the taxonomy of the mahseers (Tor spp.) of Malaysia: An integrated approach using morphology, genetics and historical records","volume":"25","author":"S Walton","year":"2017","journal-title":"Rev Fish Sci Aquac"},{"issue":"2","key":"pone.0291436.ref003","first-page":"243","article-title":"On some new records of fish from the Damodar and the Mahanadi River systems","volume":"5","author":"A.
