Diagnosis. Prostomium with oval frontal lips, short palps and short to long antennae, ceratophores with usually 3– 5 rings; peristomial cirri present. Anterior 3–8 pairs of parapodia modified but not enlarged. Hooks of modified parapodia usually tridentate (rarely bi- and tridentate), pseudocompound with short hoods; median hook sometimes becoming simple and changing to large median hook. Ventral cirri subulate on anterior 3–6 (rarely more) chaetigers. Dorsal limbate chaetae from chaetiger 1, ventral limbate chaetae compound (= spinigers) from chaetiger 4 or later until replaced by bidentate hooded subacicular hooks from chaetiger 13–29. Branchiae usually as single filaments, rarely pectinate. Tubes round in section, ranging from thin mucous to tough parchment-like inner layer covered with sand or mud.
