Diagnosis

Body short, flattened, spindle-shaped, segments 21, first achaetous. Elytra and elytrophores, 10 pairs on segments 2, 4, 5, 7, 9, 11, 13, 15, 17 and 19. Dorsal cirri on non-elytra-bearing segments with short cirrophores and short styles. Dorsal tubercles on cirrigerous segments indistinct. Branchiae well developed, arborescent, on all parapodia from segment 2. Prostomium bilobed, subtriangular anterior lobes bearing minute frontal filaments; with short median antenna and pair of short palps; without lateral antennae and eyes. First or tentacular segment fused to prostomium, visible dorsally as short ring, achaetous; stout tentaculophores lateral to prostomium with 2 pairs of short tentacular cirri; without facial tubercle. Second or buccal segment with first pair of elytra and short ventral buccal cirri. Parapodia subbiramous. Notopodia small, with few short acicular notosetae. Neuropodia short, truncate, without projecting acicular lobes; with very numerous neurosetae including upper stout, slightly hooked ones separated by partition from very numerous slender ones. Ventral cirri short. Pygidium with pair of short anal cirri. Pharynx with 5 pairs of papillae and 2 pairs of jaws. Enlarged ventral papillae on segments 11 and 12. Commensal with mussels on deep-sea thermal vents
