Diagnosis. Proboscidial papillae mainly digitiform with about 6–20 ridges; ailerons with deeply incised bases; parapodia of mid-body with two short, rounded postchaetal lobes; branchiae absent.

Description. Body up to 39.5 mm long with up to 161 chaetigers. Mid-body segments bi-annulate.

Conical prostomium consisting of about 10–13 rings; terminal ring with four appendages and basal one with pair of nuchal organs ( Fig. 2 A).

Proboscis with two types of papillae: l. numerous digitiform papillae with about 6–20 ridges; ridges U-shaped basally and V-shaped apically on posterior surface; 2. isolated, slightly shorter and broader, conical papillae with more or less distinctly straight, median, longitudinal ridge ( Figs 2 B, 10A). Terminal part of proboscis with four hook-shaped jaws arranged in a cross and accessory ailerons with deeply incised base ( Fig. 2 C).

First two pairs of parapodia uniramous; following parapodia biramous ( Fig. 2 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 on body wall slightly 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. 2 D–K). Notochaetae capillaries. Neurochaetae compound spinigers with blades of different lengths.

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

Distribution. Carter Reef, Day Reef, Lizard Island Group, North Direction Island, Yonge Reef; intertidal to 40 m.
