Description. Body small, up to 4.7 mm long, 0.21 mm wide, 33 chaetigers, usually without colour markings, but some mature specimens with transverse rows of red pigment on dorsum of anterior segments. Prostomium ovate; 4 eyes in trapezoidal arrangement, nearly in line, and 2 small anterior eyespots. Median antenna long and slender, spindle-shaped, about 1.5 times as long as combined length of prostomium and palps, inserted between posterior pair of eyes or slightly in front, lateral antennae much shorter, less than half of length of median antenna (Fig. 7A). Palps broad, similar in length to prostomium, dorsally fused all along their length except for a small notch, sometimes ventrally folded. Peristomium similar in length to following segments; tentacular cirri similar in shape to antennae, dorsal tentacular cirri similar to median antenna but shorter, ventral tentacular cirri similar in shape and length to lateral antennae. Dorsal cirri on all parapodia, similar to antennae and tentacular cirri in shape (Fig. 7A); dorsal cirri of chaetiger 1 similar in length to median antenna, remaining dorsal cirri varying in length, always shorter than those of chaetiger 1. Compound chaetae with slender shafts and elongate blades, bidentate, with subdistal tooth small and short (Fig. 7B), straight marginal spines; 1–2 dorsalmost chaetae with distinctly long blades, about 50 µm long, and 6–8 similar chaetae with shorter blades and dorsoventral gradation, 28–29 µm above, 18 µm below. Dorsal simple chaetae from midbody, slender, provided with short subdistal spines, minutely bidentate (Fig. 7C). Ventral simple chaetae in far posterior chaetigers, sigmoid, smooth, slender and bidentate. Acicula solitary, acuminate (Fig. 7D). Pharynx wide, proportionally long, through about 3–4 segments, without papillae on the opening; pharyngeal tooth small, ovate, located just in front of middle of pharynx (Fig. 7A). Proventricle similar in length and width to pharynx, with about 20–22 muscle cell rows.
Distribution. Australia (reported from all states, except the Northern Territory). Polynesia.
Habitat. Common on all shallow substrates: corals, sand, amongst algae, seagrass.
