A slender species. Prostomium longer than wide, with rudimentary prostomial horns. Chaetigers 1–8 with slender, smooth-edged, triangular lamellae, with superior dorsal lobes. Lamellae of chaetiger 9 triangular, without superior dorsal lobes, but with prechaetal lamellae below neurochaetal bundle. Thoracic chaetigers with capillary chaetae only. Abdominal lateral lamellae spatulate. Hooded hooks tridentate, in two groups,
