Diagnosis. Platynereis species having green pigmentation and abundant white pigment spots on dorsum and characteristic patch of white pigment on prostomium ( Fig. 5 D); pigment shows green fluorescence at 510–540 nm ( Fig. 5 E).

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 pectinate rows of paragnaths in Areas VII–VIII can be arranged in 5–6 patches, rather than only 5 patches.

Habitat. Lagoon and back reefs, sand, 2– 10 m.

Type locality. Ellice Islands (Funafuti) and Gilbert Islands.

Distribution. Northern Australia, tropical Indo-West Pacific.
