The new species is differentiated from its congeners by a combination of the following characters: dorsal scales in 17-17-15 rows, smooth throughout; supralabials usually eight (rarely nine); infralabials ten; one elongated loreal on each side, in contact with the eye; precloacal plate single; ventral scales 212\u2013218 (plus one or two preventral scales); subcaudals 90 or 91; maxillary teeth 13 or 14; dorsal surface of body with 28 or 29 light body bands; dorsal surface of tail with 13 cream bands, forming a distinct blotch in the vertebral region. Based on phylogenetic analyses of mitochondrial cytochrome<jats:italic>b<\/jats:italic>sequence data, the new species is recovered as the sister species to a clade containing<jats:italic>L. multizonatus<\/jats:italic>and<jats:italic>L. liuchengchaoi<\/jats:italic>with strong support from the Bayesian analysis. The new species is at least 7.5% divergent from other species within this clade in uncorrected pairwise distance calculated using a fragment of more than 1000 bp of the mitochondrial cytochrome<jats:italic>b.<\/jats:italic>This discovery increases the number of<jats:italic>Lycodon<\/jats:italic>species known from Vietnam to 16.<\/jats:p>","DOI":"10.3897\/zookeys.875.35933","type":"journal-article","created":{"date-parts":[[2019,9,10]],"date-time":"2019-09-10T11:51:04Z","timestamp":1568116264000},"page":"1-29","source":"Crossref","is-referenced-by-count":14,"title":["A new species of Lycodon Boie, 1826 (Serpentes, Colubridae) from northern Vietnam"],"prefix":"10.3897","volume":"875","author":[{"given":"Helen Y.","family":"Janssen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cuong T.","family":"Pham","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hanh Thi","family":"Ngo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minh Duc","family":"Le","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6601-0880","authenticated-orcid":true,"given":"Truong Q.","family":"Nguyen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Ziegler","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2258","published-online":{"date-parts":[[2019,9,10]]},"reference":[{"key":"35933_B1","doi-asserted-by":"publisher","DOI":"10.5962\/bhl.title.55401"},{"issue":"4","key":"35933_B2","doi-asserted-by":"crossref","first-page":"37","DOI":"10.26515\/rzsi\/v110\/i4\/2010\/158916","article-title":"Extension of the range and redescription of Lycodon jara (Shaw) (Reptilia: Serpentes: Colubridae).","volume":"110","author":"Bahuguna","year":"2010","journal-title":"Records of the Zoological Survey of India"},{"year":"1878","author":"Blanford","key":"35933_B3"},{"key":"35933_B4","first-page":"508","article-title":"Bemerkungen \u00fcber Merrem\u2018s Versuch eines Systems der Amphibien, 1.
