Type-species: Terebella lapidaria Linnaeus, 1767 , by monotypy.

Diagnosis. (after Hutchings et al. 2021b). Transverse prostomium attached to dorsal surface of upper lip; basal part as a thick crest, eyespots frequently present; distal part shelf-like. Buccal tentacles all uniformly cylindrical. Peristomium restricted to lips; lips expanded, upper lip relatively short, hood-like, about as long as wide; large, button-like to cushion-like, mid-ventral lower lip. Segment I conspicuous all around, dorsally narrow, expanded ventrally, frequently with low mid-ventral lobe marginal to mouth; other lobes on anterior segments absent. Anterior segments highly glandular ventrally, with discrete, smooth to slightly crenulated, rectangular to trapezoidal midventral shields. Three pairs of branching branchiae with short main stems, usually on SG II – IV, but sometimes on discontinuous segments. Conical notopodia beginning on SG IV, extending for a variable number of segments, frequently to posterior body; notochaetae medially winged and distally serrated, and alimbate and serrated, frequently with blade at an angle, usually with transition on types of chaetae from anterior to midbody notopodia. Neuropodia beginning on SG V, as low sessile ridges throughout; neurochaetae as short-handled avicular uncini, in completely intercalated to partially back to back double rows from SG XI until posterior body. Nephridial papillae on SG III, genital papillae usually present from SG VI, extending for a variable number of segments, between parapodial lobes. Pygidium smooth to slightly crenulated .
