A new species of Polydora is described from the Catalan coast of the northwestern Mediterranean Sea. The species has exclusively been found in association with specimens at the three growth stages of the excavating sponge Cliona viridis, and is closely related to Polydora armata. It mainly differs from its closest relatives by: (1) the rounded entire anterior margin of the prostomium; (2) the unusual hook-shaped row arrangement of the modified spines on its posterior notopodia; and (3) the stout flattened modified spines, which have tips hooked in different degrees depending on their position on the notopodia.
