. The original description indicates that the cephalic cage chaetae are missing but this is explained by the fact that the anterior end is missing, which is confirmed also by the lack of the dorsally displaced first chaetiger. So far, this species is unique in having a large number of notochaetae, which unlike other species, are less markedly thinner than neurochaetae, and by the thick sediment cover of body papillae. However, another species also possesses more than the usual number of notochaetae (1–3),

As indicated below, this latter material includes specimens with anterior ends and showing different degrees of abrasion, such that a better understanding of both species is now possible. Their cephalic cage, as can be seen in one of the species, has very few, thin chaetae and consequently they cannot belong in
