Diagnosis. Rim of cephalic veil with numerous long cirri. Cephalic veil completely free from operculum, forming a dorsal semi-circular lobe covering the bases of numerous peristomial palps. Raised opercular margin smooth. Chaetigers 1–3 (segments V–VII) with notopodia and notochaetae only, chaetigers 4 to 15 or 16 biramous with notopodia, neuropodia, notochaetae and neurochaetae, chaetiger 16 or 17 with notopodia and notochaetae only (16/ 12 or 17/13). Two types of notochaetae, smooth and serrated (or plumose). Neurochaetal uncini with major teeth arranged in two or three (or more) rows. Posterior 5 segments fused to form a flattened plate or scaphe and distinctly separated from the abdomen (based on Hutchings & Peart 2002: with underline—this study).
