  • Rullierinereis ancornunezi n. sp., collected from sandy and maërl bottoms from 19-55 m depth around Lanzarote island, is described. The new taxon is characterized by having a reduced or absent upper notopodial ligule in biramous parapodia of chaetigers 3-9 and in the middle region from chaetiger 26 onwards, and also by the shape of the homogomph notopodial falciger blade, which is short and serrated. A comparison with morphologically similar species is made. Other nereidid species collected were: Nereis lamellosa Ehlers, 1864, Nereis rava Ehlers, 1864, Neanthes caudata (Delle Chiaje, 1827) and Neanthes rubicunda (Ehlers, 1864). A map of the distribution of these species is presented.
