Prostomium with two lateral slender antennae and one median conical and short. Eyes not present. Long papillae on anterior margin of prostomium. Segment 1 cirri digitiform, similar in length to lateral antennae. Papillae covering completely dorsum and ventral side of the body distributed in several irregular transversal rows per segment.

Ventral cirri conical, slightly longer than parapodia but not exceeding length of prechaetal lobes. Several papillae on each face of parapodia, 3 located distally over dorsal edge of parapodia.
