A large, stout species. Prostomium wider than long, squared anterior margin. Chaetigers 1–8 with foliaceous, smooth-edged lamellae, with superior dorsal lobes. Chaetiger 9 with triangular postchaetal lamellae in both rami, with superior dorsal lobes in the notopodia and small prechaetal lamellae at base of neurochaetal bundle. Thoracic chaetigers with capillary chaetae only. Abdominal lateral lamellae spatulate. Hooded hooks tridentate, in two groups,
