The genus <jats:italic>Genitocotyle<\/jats:italic> is little studied with only five recognized species. Recent phylogenetic advancements have refined Opecoelidae classification, recognizing 15 subfamilies, including opecoelins, distinguished by the absence of a cirrus sac and a canalicular seminal receptacle. Within this subfamily, the genus <jats:italic>Genitocotyle<\/jats:italic> remains understudied, with only five recognized species. The aim of this study is to describe a new species and to clarify a long-standing taxonomic ambiguity.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>Two historical specimens of <jats:italic>Genitocotyl<\/jats:italic>e from <jats:italic>Apogon imberbis<\/jats:italic> off Madeira, preserved in the Natural History Museum, London, were examined alongside newly collected specimens from Algerian waters.
