described to date, the neuropodial hooks usually start around segment 20 at the latest and sabre chaetae are usually present before this. However, given that the largest specimen available for examination was only 31 chaetigers long, it is possible that sabre chaetae/neuropodial hooks may start later in body.

We therefore choose to describe but not name the species to enable future workers to identify it with the hope that complete specimens will be discovered and allow a more comprehensive description.
