The prostomium tapers to a blunt tip and bears a pair of
terminal anterior antennae and a pair of ventral palps; the
antennae and palps are of a similar size.
Irregular scattered brown pigment spots are present on the
prostomium and dorsum; eyes are apparently absent. The
pharynx has a terminal ring of papillae; jaws are absent. The peristomium, reduced dorsally, is present
ventrally as lips around the buccal opening; it lacks cirri or
other appendages. The first segment has neuropodia with
neurochaetae and reduced ventral cirri; notopodia and
notochaetae are lacking. All other segments are biramous, with
widely separated parapodial lobes. Notopodia and neuropodia
have small postchaetal and larger prechaetal lobes, and small
dorsal and ventral cirri, respectively. Neuropodia are longer
than notopodia. Aciculae are present in both parapodial lobes. Notochaetae are capillaries, serrated on one
margin, and neurochaetae are compound
spinigers similarly serrated. The pygidium is
bulbous and has a pair of long cirri.
