Abstract:Atherospio guillei (Laubier and Ramos, 1974) comb. nov. is redescribed based on new material collected during a benthic survey in the German Bight, North Sea. Main characteristics of this species are a deeply incised prostomium, modified neurochaetae on chaetiger 5 superior to a small bundle of capillaries, branchiae fully fused to notopodial lamellae with digitiform distal process from chaetiger 7 over a limited number of succeeding chaetigers, predominately unidentate curved hooks with closely applied sheath from chaetiger 13-15 and a pygidium surrounded by several pairs of lateral cirri. Atherospio is closely related to Pygospiopsis and Pseudatherospio. Interrelationships of these genera are discussed.
Keywords:Atherospio guillei   Atherospio   Polydora   Pseudatherospio   Pygospiopsis   Spionidae
