Rare, Indigenous

Small, up to 7.4 mm for 60 chaetigers. Prostomium flaring to form V, sometimes T, shape.  Caruncle to ends of chaetiger 4 to 6.1 or 2 pairs of eyes in trapezoid arrangement, anterior pair double the size of posterior pair. Short occipital tentacle.
Notochaetae absent on Chaetiger 1. Chaetiger 5 weakly modified. Two types of modified spines arranged in U-shape; inner simple spines long with bulbous asymmetrical subdistal thickening, convex edge with flange-like appearance, rounded point; outer pennoned spines spoon-shaped with bristles lining concavity and tapering point, larger than simple spines. Hooded hooks start on chaetiger 8 onwards, no accompanying neurochaetae.
Branchiae start on chaetiger 7, barely touch along the midline chaetiger 9 onwards. On 14 – 25 pairs in complete specimens.
Pygidium large and fleshy, dorsal and ventral notches form lateral lobes.
