Diagnosis. Ceratonereis species with tentacular cirri extending to chaetigers 15–20 and dorsal cirri about as long as body is wide ( Fig. 1 C); only subtle body pigmentation when alive (presence of inter-segmental orange pigment on anterior segments), which usually fades in preserved specimens ( Fig. 1 D); Area III of proboscis with slightly fewer paragnaths (6–9) than Area IV ( Fig. 1 E); dorsal notopodial ligule similar in size to ventral neuropodial ligule in anterior chaetigers.

Remarks. The specimens from Lizard Island agree well with Perkin’s (1980) redescription of the species. They resemble Ceratonereis longiceratophora Hartmann-Schröder, 1985 , but may be distinguished from this species as C. longiceratophora has more paragnaths in Area III (13) compared to Area IV (10).

Habitat. Most common on reef slope associated with Halimeda and rubble, 3– 30 m. Lizard Island and Day Reef, Outer Barrier Reef.

Type locality. Oahu, Hawaii.

Distribution. Hawaii, Japan. First record for Lizard Island.
