Pionosyllis serratistosa (Syllidae, Eusyllinae) is characterized by having blades of compound setae with strongly curved subdistal teeth, acicula with a crown of fine spines, and dorsal cirri alternating short and long. Autolytus logoprimicirratus (Syllidae, Autolytinae) is characterized by large size, long dorsal cirri, especially those on setiger 1, and a long pharynx and proventriculus.
