The genus Acanthochitona can be easily distinguished from other chitons by having eighteen tufts of bristles on the dorsal side of the densely spiculose girdle. In the North-East Atlantic, five species of this genus have been recognised so far: A. crinita (Pennant, 1777), A. discrepans (Brown, 1827), A. fascicularis (Linnaeus, 1767), A. oblonga Leloup, 1968 and A. pilosa Schmidt-Petersen, Schwabe et Haszprunar, 2015. The nomenclature of A. crinita, A. discrepans and A. fascicularis was confused for a very long time until Kaas (1985) designated type specimens for them and provided a brief key. However, his work lacked detailed descriptions of the three species and some authors doubted that A. discrepans constitutes a separate species. Subsequently, the taxonomic status of A. discrepans has remained unclear.Here, we implemented an integrative approach which combined morphology and molecular evidence to show that Acanthochitona discrepans is, indeed, a valid species and we present re-descriptions for A. crinita, A. discrepans and A. fascicularis.Taxonomic Coverages
