The genus currently contains only three species associated with marine fish as intermediate hosts and fish-eating birds as definitive hosts. Here, specimens of <jats:italic>Scaphanocephalus<\/jats:italic> were collected from the Osprey, <jats:italic>Pandion haliaetus<\/jats:italic>, and the White mullet, <jats:italic>Mugil curema<\/jats:italic> in the Yucat\u00e1n Peninsula, Mexico. We report for the first-time DNA sequences of adult specimens of <jats:italic>Scaphanocephalus<\/jats:italic>, particularly <jats:italic>S. expansus<\/jats:italic>, as well as a sequence of a different species sampled as metacercaria. Morphological comparisons of <jats:italic>Scaphanocephalus expansus<\/jats:italic> confirmed the identity of the adult specimens, with minor morphological variations; Scanning electron photomicrographs were included, and the species was re-described. Phylogenetic analysis based on 28S rDNA sequences showed that <jats:italic>Scaphanocephalus<\/jats:italic> is monophyletic within Opisthorchiidae and consists of three independent lineages. Sequences of adults are identical to those of <jats:italic>S. expansus.<\/jats:italic> Instead, the sequence of the metacercaria sampled from the mesentery of <jats:italic>Mugil curema<\/jats:italic> nested with specimens reported as <jats:italic>Scaphanocephalus<\/jats:italic> sp. from a labrid fish in the Mediterranean Sea, herein named it as <jats:italic>Scaphanocephalus<\/jats:italic> sp. 2.<\/jats:p>","DOI":"10.1017\/s0022149x23000834","type":"journal-article","created":{"date-parts":[[2023,12,14]],"date-time":"2023-12-14T09:55:17Z","timestamp":1702547717000},"source":"Crossref","is-referenced-by-count":3,"title":["<i>Scaphanocephalus<\/i> spp. (Trematoda: Opisthorchiidae) in intermediate and definitive hosts of the Yucat\u00e1n Peninsula, Mexico, with a re-description of <i>Scaphanocephalus expansus<\/i>"],"prefix":"10.1017","volume":"97","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4871-0901","authenticated-orcid":false,"given":"M.
