Chaetae include one to two conspicuous crook-like spines in neuropodia of chaetiger 1; stout sabre chaetae in inferiormost position usually present from chaetiger 4; bacillary chaetae maybe exposed in chaetigers 5–9; capillaries present in both parapodial rami along the body arranged in one to three distinct or indistinct rows; hooks present in posterior region, usually quadridentate with main fang surmounted by single tooth and two smaller apical teeth in parallel position; with or without secondary hoods. Transverse dorsal ciliated crests usually present. Clusters of cilia herein referred to as ‘lateral ciliated patches’ present or absent in parapodia of the middle body region. Ventrolateral pouches present or absent in posterior region between neuropodia. Pygidium with two or more anal cirri.

in our source material from abyssal depths was suggested based on sequence analysis. Two species are newly described here; the identity of the third species and its potential assignment to a known species is discussed. The three putative species are all morphologically very similar and characters useful for morphological species delimitation are difficult to find. Prostomial characters, nuchal organs, both distribution and details of parapodial glandular organs along the body, as well as many chaetal characters, are in good agreement among the three species (see details in the species descriptions). In all three species sabre chaetae are present from chaetiger 4 throughout the body, but are oħen strikingly long in anterior chaetigers compared to those in more posterior and hook-bearing segments. Neuropodial quadridentate hooks with reduced hoods start on chaetiger 15. All three species possess very long capillaries in notopodia of the posterior part of the median region, and even longer capillaries in posterior notopodia. Morphological differences concern the ciliated patches, a character that has not been formerly described for
