Diagnosis. Platynereis species pink in colour ( Fig. 5 F) and showing less intense fluorescence pattern under green light (510–540 nm) compared to P. polyscalma ( Fig. 5 G); lacking white prostomial pigment patch of latter species ( Fig. 5 D).

Remarks. This species was first reported from Lizard Island by Hutchings & Reid (1991). The present specimens fit the description of these authors; the only additional variation noted is that the longest tentacular cirri extend to about chaetiger 12.

Habitat. Lagoon to reef slope, sand and coral rubble, 2 m.

Type locality. Ningaloo, Western Australia.

Distribution. Northern Australia.
