This study examined a population of rainbow water snakes, <jats:italic>Enhydris enhydris<\/jats:italic> (Schneider, 1799), collected from southern Thailand. Adult nematodes consistent with <jats:italic>Tanqua<\/jats:italic> were found in the stomach. Various morphometric, meristic and qualitative morphological variables, including size, ratios, distances, cephalic appearance, the number of caudal papillae and other features, serve to distinguish the specimens from other species within the genus. In particular, <jats:italic>Tanqua anomala<\/jats:italic> and <jats:italic>Tanqua diadema<\/jats:italic>, which closely resemble our <jats:italic>Tanqua<\/jats:italic> specimens, can be differentiated by key diagnostic characteristics such as a retractable head, the distance from the anterior end to the cervical sac, the relative positions of caudal papillae and excretory pore, and the length of the uterus. Molecular analysis (<jats:italic>COI<\/jats:italic> and 18s rRNA genes) confirmed its status as a species of <jats:italic>Tanqua<\/jats:italic>, genetically distinct from <jats:italic>Tanqua tiara<\/jats:italic>, and matching the genetic sequence found in larvae of <jats:italic>Tanqua<\/jats:italic> sp. from a snakehead fish species from Bangladesh. <jats:italic>Tanqua siamensis<\/jats:italic> sp. nov. is described, supported by morphological traits, microscopic illustrations and genetic information. This study reports the first evidence of a caudal papillary pair in females. This species causes significant lesions on the stomach wall of the snake host, raising possible issues for snakes held in captivity regarding food hygiene and parasite protection.<\/jats:p>","DOI":"10.1017\/s0031182024000908","type":"journal-article","created":{"date-parts":[[2024,9,23]],"date-time":"2024-09-23T11:39:01Z","timestamp":1727091541000},"page":"821-831","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":5,"title":["A new nematode species, <i>Tanqua siamensis<\/i> sp. nov.
