Grube, 1850

Small, active, carnivorous worms found mostly amongst colonial sedentary animals and seaweeds, occasionally in a mucus tube. They typically have long, fingerlike and often annulated dorsal cirri. All possess an eversible pharynx, usually armed with a single piercing tooth or a trepan (circlet of small teeth), connected to the barrel-shaped muscular proventriculus (gizzard), which may be visible through the body wall. The rounded head has usually four large eyes and bears three antennae; a pair of flattened palps may be separate, joined at the base or wholly fused together in the mid-line. Peristomium limited to lips. First segment with one or two pairs of tentacular cirri only.
Parapodia unimous, mostly with only few compound chaetae. Aciculae present. Dorsal cirri always present, ventral cirri absent in Autolytinae.
Chaetae compound and simple.
Pygidium with one pair of cirri (Syllidae).

After: Fauchald and Rouse, 1997 and Hayward and Ryland, 1990.
