Diagnosis. Proboscidial papillae mainly digitiform with straight, median, longitudinal ridge; ailerons with deeply incised bases; parapodia of mid-body with slightly longer neuropodial than notopodial prechaetal lobes and two short postchaetal lobes; branchiae absent.

Description. Body up to 20 mm long with up to 76 chaetigers. Mid-body segments bi-annulate.

Conical prostomium consisting of about 8–9 rings; terminal ring with four appendages and basal one with pair of nuchal organs ( Fig. 6 A).

Proboscis with two types of papillae: l. numerous digitiform papillae with straight, median, longitudinal ridge on posterior surface and sometimes additional V-shaped ridge near tip; 2. isolated, slightly shorter and broader, conical papillae without distinct ridges ( Figs 6 B, 10E). Terminal part of proboscis with four hook-shaped jaws arranged in a cross and accessory ailerons with deeply incised base ( Fig. 6 A, C).

First two pairs of parapodia uniramous; following parapodia biramous ( Fig. 6 D–K). Two slender triangular to digitiform prechaetal lobes; neuropodial lobe usually slightly longer and wider than notopodial lobe; both lobes becoming slightly thinner in posterior parapodia; in last parapodia notopodial lobe distinctly shorter than neuropodial one. Two shorter, rounded postchaetal lobes. Dorsal cirri from 3rd parapodium, conical to oval; inserted - most clearly in anterior part of body - on body wall far above parapodial base. Ventral cirri slender triangular to digitiform, about as long as postchaetal lobes; in posterior parapodia slender and elongated; in last parapodia about as long as neuropodial prechaetal lobe; situated medio-ventrally on parapodia. Branchiae absent.

Noto- and neuropodia each with a single acicula ( Fig. 6 D–K). Notochaetae capillaries. Neurochaetae compound spinigers with blades of different lengths.

Pygidium with dorsal anus and terminal pair of slender, elongated cirri.

Distribution. Lizard Island Group, North Direction Island, Yonge Reef; 0.5– 40 m.
