Two new species of Desmoscolex (Desmoscolex) Claparède, 1863 from Cassidagne Canyon (deep-sea Mediterranean), namely Desmoscolex (Desmoscolex) nibelungus sp. nov. and Desmoscolex (Desmoscolex) valkyria sp. nov. are described. Desmoscolex (D.) nibelungus has 17 main rings and the typical desmoscolecid setal pattern. The most evident features to distinguish it from the rest of D. (Desmoscolex) with these characteristics are the protuding lip region not covered with concretion material, the cephalic region that apparently lacks setae and the beak-shaped posterior-most main ring.
