Specimens of <jats:italic>Chauhanea mediterranea<\/jats:italic> Euzet &amp; Trilles, 1960 and <jats:italic>Rhinecotyle crepitacula<\/jats:italic> Euzet &amp; Trilles, 1960 (Polyopisthocotyla) are redescribed based on newly collected material. A careful examination of <jats:italic>Ch. mediterranea<\/jats:italic> revealed inaccuracies in previous interpretations of the female openings. The midventral opening, previously referred to as the \u2018vaginal opening\u2019 in <jats:italic>Pseudochauhanea<\/jats:italic> Yamaguti, 1965 and used to distinguish this genus from <jats:italic>Chauhanea Ramalingam, 1953<\/jats:italic>, is demonstrated to be the uterus, as confirmed by the presence of eggs in the thin-walled duct associated with this opening. The lateral position of the cirrus and vagina is also confirmed. Consequently, <jats:italic>Pseudochauhanea<\/jats:italic> is synonymized with <jats:italic>Chauhanea<\/jats:italic>, resulting in the following new combinations: <jats:italic>Ch. elegans<\/jats:italic> Fuentes-Zambrano, 1997 n. comb.; <jats:italic>Ch. elongata<\/jats:italic> Kritsky, Bilqees &amp; Leiby, 1972 n. comb.; <jats:italic>Ch. macrorchis<\/jats:italic> Lin, Liu &amp; Zhang in Zhang, Yang &amp; Liu, 2001 n. comb.; <jats:italic>Ch. mexicana<\/jats:italic> Lamothe, 1967 n. comb.; <jats:italic>Ch. sphyraenae<\/jats:italic> Yamaguti, 1965 n. comb. A detailed investigation of the clamp sclerites of <jats:italic>Ch. mediterranea<\/jats:italic> indicates that both <jats:italic>Chauhanea<\/jats:italic> and <jats:italic>Cotyloatlantica<\/jats:italic> Bravo-Hollis, 1984 share the subdivision of the basal oblique sclerite, which is a continuation of the marginal sclerite in the anterior jaw, a key feature used to distinguish these genera. As a result, <jats:italic>Cotyloatlantica<\/jats:italic> is also synonymized with <jats:italic>Chauhanea<\/jats:italic>, and its species are transferred as follows: <jats:italic>Ch. pretiosa<\/jats:italic> (Bravo-Hollis, 1984) n. comb. The reinstatement of <jats:italic>Ch. mediterranea<\/jats:italic> Euzet &amp; Trilles, 1960 as a valid name is supported, and an amended diagnosis of <jats:italic>Chauhanea<\/jats:italic> is provided. Additionally, <jats:italic>R. crepitacula<\/jats:italic> is accurately redescribed, with a new geographical locality record and an assessment of morphometrical and anatomical variations between Mediterranean and oceanic specimens.<\/jats:p>","DOI":"10.1017\/s0022149x2500032x","type":"journal-article","created":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T07:12:43Z","timestamp":1745478763000},"source":"Crossref","is-referenced-by-count":1,"title":["New insights into two poorly known monogeneans (Platyhelminthes), gill parasites of the European barracuda <i>Sphyraena sphyraena<\/i> (Teleostei, Sphyraenidae) with notes on <i>Chauhanea<\/i> Ramalingam, 1953 and closely related genera"],"prefix":"10.1017","volume":"99","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9620-8273","authenticated-orcid":false,"given":"C.","family":"Bouguerche","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2025,4,24]]},"reference":[{"key":"S0022149X2500032X_r20","first-page":"156","article-title":"Bychowskicotylinae subfam. n. and some notes on the classification of monogeneans of the family Gastrocotylidae Price, 1943","volume":"24","author":"Lebedev","year":"1969","journal-title":"Parazit.
