Adult specimens were collected from the intestines of three white-nosed coatis (<jats:italic>N. narica<\/jats:italic>), whereas cystacanths (larval form) were found in the body cavities of two amphibian species (paratenic hosts) in localities from northern and southeastern Mexico. Morphologically, both stages were identified as <jats:italic>O. luehei<\/jats:italic> (Travassos, 1917) on the basis of the following features: trunk cylindrical, narrow anteriorly, enlarging midbody, tapering gradually to narrow posteriorly; proboscis globular with six circular rows of hooks with six hooks each, decreasing in size posteriorly; neck short with sensory papilla; tubular lemnisci long, extending to the posterior region; protonephridia dendritic type; and eight cement glands, compact with a single giant nuclei. Sequences from cytochrome c oxidase subunit 1 from mtDNA were aligned and compared with sequences available in GenBank. Phylogenetic analyses revealed that adults and cystacanths formed a clade with two other isolates identified as <jats:italic>Oncicola<\/jats:italic> sp<jats:italic>. and O. luehei<\/jats:italic> from Mexico. The intraspecific genetic divergence among the isolates was low, ranging from 0.0% to 3.0%, indicating that the two stages of the life cycle belong to the same species. The haplotype network was inferred with 11 sequences and revealed a lack of shared haplotypes between populations, suggesting a reduced recombination rate and a high pattern of genetic variation among individuals. Finally, these new records of <jats:italic>O. luehei<\/jats:italic> increase the distribution range of <jats:italic>O. luehei<\/jats:italic> on both coasts of Mexico.<\/jats:p>","DOI":"10.1017\/s0022149x24000944","type":"journal-article","created":{"date-parts":[[2025,2,5]],"date-time":"2025-02-05T06:32:06Z","timestamp":1738737126000},"source":"Crossref","is-referenced-by-count":0,"title":["A morphological and molecular study of adults and cystacanths of <i>Oncicola luehei<\/i> Travassos, 1917 (Acanthocephala: Archiacanthocephala), from the Neotropical region of Mexico"],"prefix":"10.1017","volume":"99","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1054-1930","authenticated-orcid":false,"given":"A.L.","family":"Sereno-Uribe","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0499-6768","authenticated-orcid":false,"given":"M.P.","family":"Ortega-Olivares","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4871-0901","authenticated-orcid":false,"given":"M.T.","family":"Gonz\u00e1lez-Garc\u00eda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7519-379X","authenticated-orcid":false,"given":"M.I.","family":"Grano-Maldonado","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7050-8825","authenticated-orcid":false,"given":"M.","family":"Garc\u00eda-Varela","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2025,2,5]]},"reference":[{"key":"S0022149X24000944_r18","doi-asserted-by":"publisher","DOI":"10.1017\/CBO9780511541902"},{"key":"S0022149X24000944_r27","first-page":"8","article-title":"Reconsideration of the acanthocephalan genus Echinopardalis, with a description of adult E. atrata and a key to genera of the Oligacanthorhynchidae","volume":"56","author":"Nickol","year":"1989","journal-title":"Proceedings of the Helminthological Society of Washington"},{"key":"S0022149X24000944_r33","doi-asserted-by":"publisher","DOI":"10.1093\/molbev\/msn083"},{"key":"S0022149X24000944_r31","unstructured":"Petrochenko, VI (1958) [Acanthocephala of Domestic and Wild Animals], vol. 2.
