Terebellids with 0–3 pairs of branchiae, each consisting on unbranching filaments originating all from the same point on each side of pair, or branching or unbranching filaments originating from single basal stem on each side of pair. Ventral surface of body highly glandular anteriorly, discrete ventral shields present. Notopodia extending for variable number of segments, with distally winged or distally serrated notochaetae, both types with variable morphology. Neuropodia as sessile ridges until segment on which notopodia terminate, frequently as raised pinnules from first segment after notopodia terminate. Uncini about as long as high or higher than long, with dorsal button situated away from anterior margin of uncini, usually forming tuft of bristles below tip of main fang, and conspicuous prow; long-handled uncini sometimes present on some segments with biramous parapodia; uncini arranged in double rows at least on some segments with biramous parapodia.
