In members of this genus there are 12 pairs of elytrae and 26 segments. This species is the only polynoid with uniform very dark grey pigmentation throughout. This species has 2-3 dark pigmented crescents on each elytron, resulting in a very distinctive dorsal pattern. The elytrae are smooth. Body up to about 5 cm long.
This scale worm is very often seen crawling over the banded brittle star (Ophionereis schayeri) but the nature of the association between the two species is unknown. Both the brittle star and the scale worm can also often be found by themselves.
