Quadrangular prostomium, T-shaped, with two short lateral horns and a small postero-dorsal elevation, near peristomium. Mouth formed by one pair of upper lips and one pair of lower lips. Branchiae present from chaetiger 2–5. Dorsally, anterior region quadriannulate, becoming pentannulated posteriorly. Ventrally, chaetiger 1–2 triannulate, then quadriannulate to pentannulate on posterior chaetigers. Short spinous chaetae present on chaetiger 1 anterior to capillaries, being replaced by 5–6 lyrate chaetae with equal tynes on chaetiger 2.
