Dorsal cirri moderately long, alternating in length in midbody. Compound chaetae bidentate with short spines on margin; one of each parapodium slightly longer and slender than rest. Posterior aciculae acuminate. Pharynx long and slender. <b>Description</b>. Longest complete specimen examined 6.7 mm long, 0.3 mm wide, with 59 chaetigers (up to 7.1 mm with 92 chaetigers; <i>fide</i> Hartmann-Schröder, 1982; Licher 1999). Body of medium size, slender, without colour pattern. Prostomium oval, with four eyes in trapezoidal arrangement and two anterior eyespots (Fig. 12A). Palps slightly shorter than prostomium. Median antenna arising between posterior eyes, with 19 articles, longer than combined length of prostomium and palps; lateral antennae distinctly shorter than median one, with 14 articles. Peristomium distinctly shorter than subsequent segments (Fig. 12A). Dorsal tentacular cirri similar in length to lateral antennae, with about 15 articles; ventral tentacular cirri slightly shorter than dorsal ones. Dorsal parapodial cirri relatively short, except some of anterior segments (Fig. 12A), with distinct coiled, dark, refracting inclusions in most articles, irregularly alternating long and short; long dorsal parapodial cirri similar in length to body width, with about 13–15 articles in midbody, short dorsal parapodial cirri in midbody with about 9–10 articles. Ventral parapodial cirri digitiform. Compound chaetae heterogomph falcigers, similar throughout body, with bidentate blades, both teeth similar, proximal tooth well marked (Fig. 12C, D, E); blades with short, thin, spines. On each parapodia, few (1–3) most dorsal falcigers with slender, elongated blades, and remaining shorter, more markedly bidentate (Fig. 12C, D, E). Anterior parapodia each with 10–12 compound chaetae; blades 26 μm long above, 13 μm long below (Fig. 12C); midbody parapodia with 8–9 compound chaetae each, blades 22 μm long above, 14 μm long below (Fig. 12D); posterior parapodia with 4–6 compound chaetae each, with blades 19 μm long above, 13 μm long below (Fig. 12E). Dorsal simple chaetae only on posterior parapodia, slightly bidentate (Fig. 12F). Ventral simple chaetae only on far posterior segments, slender, markedly bidentate (Fig. 12G).Anterior parapodia with three aciculae, one straight and two slightly acuminate (Fig. 12H); midbody parapodia with two aciculae, one straight and other markedly acuminate, subdistally inflated (Fig. 12I), solitary and strongly acuminate, subdistally inflated in posterior parapodia (Fig. 12J, K). Pharynx long, slender, extending through about nine segments; pharyngeal tooth on anterior margin of pharynx (Fig. 12A). Proventricle through 5–6 segments, with about 28–30 muscle cell rows. Pygidium with two anal cirri, similar to long dorsal cirri, and median stylus. <b>Habitat</b>. From intertidal to 30 m, associated with sand, algae and coral rubble. <b>Distribution</b>. Australia (SA, WA).
