The nudibranch known as the Spanish dancer, <i>Hexabranchus sanguineus</i>, is a classic example with over 200&nbsp;years of taxonomic confusion. Currently, <i>H. sanguineus</i> is accepted by most authors as a single species from the Indo-Pacific Ocean with <i>Hexabranchus morsomus</i> as a valid species from the Atlantic Ocean. Yet, despite these species being highly studied, their systematic status remains debatable. Over 30 synonyms have been proposed for <i>H. sanguineus</i> and even a distinct genus for <i>H. morsomus</i>. Here we provide, for the first time, a comprehensive review of all proposed names and an integrative taxonomic revision of the genus including morphological and molecular data. Our results reveal that <i>H. sanguineus</i> is a complex of five species: four previously described and an undescribed species, one of the largest nudibranchs in the world: <i>Hexabranchus giganteus</i> sp. nov. The genus <i>Caribranchus</i> is considered a junior synonym of <i>Hexabranchus</i> Ehrenberg, 1828 and the ontogeny of color pattern is discussed.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A Spanish dancer?
