Heron Island [Great Barrier Reef] under dead coral slab at the reef crest, 12 November 2000. 12 mm long. PHOTOS: Julie Marshall.
Described as rich green with a scattering of large and small opaque white spots. The large spots are on low papillae. There is a broad band at the margin of the parapodia which is cream to light yellow. There is a Y-shaped opaque white mark on head that extends to the base of the rhinophores which is follwed by a patch of green then another opaque white patch. The tips of the rhinophores are orange, and there is also an orange margin to the anterior edge of the foot.
These photos from Heron Island lack the broad white/cream parapodial border noted in the original description.
