Prostomium with antennae and palps; palps simple. Prostomium with pronounced anterior projection between antennae; lacking eyespots, or with one pair of eyespots (indistinct, near posterior margin of prostomium); Eyespots absent from anterior chaetigers. Pharynx with bifid terminal papillae present; 20 papillae (plus two additional simple papillae, in mid-dorsal and mid-ventral positions). Subterminal papillae present; Enlarged median subdistal dorsal papilla absent. Pharynx with 22 rows of subdistal papillae; each row made up of 5–7 papillae. Verrucae present; throughout entire basal region of pharynx (despite Rainer & Hutchings' 1977 description). Dorsal cirri present from chaetiger 1; short and digitate on chaetiger 1; larger, digitate and expanded basally on subsequent chaetigers. Dorsal interramal cirri present, from chaetiger 3, cirriform, roughly circular in cross-section, curve outward initially. Dorsal interramal cirrus with basal digitiform process; chaetigers 10–30 (at least). Ventral interramal cirri absent. Specialised dentate chaetae absent from notopodium of chaetiger 1.

Marine, inshore to marine, shelf.
The anteriorly produced prostomium immediately distinguishes this species from all other Australian nephtyids.
