Diagnosis. Proboscis with different types of papillae, conical papillae with distal beaks and basally with two long stilts; 10–20 pairs of chevrons; 29–46 uniramous chaetigers, following biramous; notochaetae capillaries, neurochaetae compound spinigers.
Description. Body up to 25.5 mm long with up to 120 chaetigers. Segments uni-annulate, but median part of dorsum sometimes appears to be bi-annulate.
Conical prostomium consisting of about 8–9 rings; terminal annulus with four biarticulate appendages and basal one with pair of nuchal organs. Pair of basal subdermal eyes may be present (Fig. 13 A).
Proboscis on distal part with longer conical papillae with distal beaks and basally with two long stilts (Fig. 17 A–B); other papillae more heart-shaped. Macrognaths quadri- to hexadentate; 2–4 H+v/w-shaped dorsal and 2–3 (usually three) H+v/w-shaped ventral compound micrognaths, dorsal arc additionally always with four slightly larger, simple rod-like micrognaths in outer position and between other ones. 16–20 chevrons on each side of proboscis; basal chevrons distinctly smaller than distal ones (Fig. 17 C–D).
First chaetigers with only one neuropodial pre- and one postchaetal lobe (Fig. 13 B); second, lower prechaetal lobe developed from chaetiger 12–13; both prechaetal lobes digitiform, upper one slightly longer and broader than lower one; conical to triangular postchaetal lobe always distinctly shorter (Fig. 13 C). 36–38 uniramous chaetigers, following parapodia biramous with conical notopodial prechaetal lobes and shorter, rounded to conical postchaetal lobes (Fig. 13 D). From 38th to 41th chaetiger parapodia enlarged and with noto- and neuropodia clearly separated (Fig. 13 E–G); lobes of about same shape as before; in posterior parapodia notopodial lobes, lower neuropodial prechaetal lobes and neuropodial postchaetal lobes shorter and upper neuropodial prechaetal lobes slightly more slender (Fig. 13 H–I). Dorsal cirri on anterior chaetigers digitiform, about as long as neuropodial postchaetal lobes (Fig. 13 B–C); in anterior biramous parapodia slightly longer than notopodial prechaetal lobes (Fig. 13 D); in enlarged biramous parapodia more conical, about as long as notopodial prechaetal lobes (Fig. 13 E–G); in posterior parapodia slender, elongated and more digitiform (Fig. 13 H–I). Ventral cirri in anterior parapodia digitiform, about as long as lower neuropodial prechaetal lobes (Fig. 13 B–D); in enlarged biramous parapodia more conical, about as long as neuropodial postchaetal lobes (Fig. 13 E–G); in posterior parapodia slender, elongated and more digitiform, slightly longer than neuropodial postchaetal lobes (Fig. 13 H–I).
Noto- and neuropodia each with a single acicula (Fig. 13 B–I). Notochaetae capillaries. Neurochaetae compound spinigers with blades of different lengths.
Pygidium with dorsal anus; cirri not observed.
Distribution. Lizard Island Group; 12–21.2 m.
