Three equally long, subulate branchiae just posterior to nuchal organs, one medial, with smooth sides, two lateral with 90° projection one-third to one-half distance from base. Notochaetae broad and flattened with a fine, spinous tip. Compound neurochaetae with short (barely as long as the medial element is wide), straight, round in cross section, spinous distal element and broad flattened medial element.
