Resumo

A new species of dorid nudibranch, Doris adrianae sp. nov. is described, from the Ría de Ferrol (NW Iberian Peninsula) on rocky bottoms, between 11 and 20 m deep, where its prey, the sponge Polymastia boletiformis (Lamarck, 1815) is common. The new species is oval-shaped and yellow to yellow-orange in colour, with the dorsum covered by rounded tubercles of various sizes, reinforced by tegumentary spicules. This new species is characterised by having numerous integumentary and fusiform calcareous spicules, mainly grouped in multispicular bundles resulting in a complex and very dense skeletal structure, giving the animal great consistence without losing flexibility. In addition, it differs from other known species of the genus Doris Linnaeus, 1758 by various external and internal characters, mainly by the coloration and the shape of the tubercles and the morphology of the radula, the digestive and reproductive systems. Doris adrianae sp. nov. also presents a marked genetic distance in the barcode fragment (cox1-5’) with other species of the genus Doris.
