Originally described from East Africa but has an Indo-West Pacific distribution.
Solitary Is., Coffs Harbour region, northern New South Wales. November 1989. PHOTOS: Bill Rudman.
Grows to about 15mm long. The whole of the animal, including the gills and the rhinophores, is bright yellow. There is a thin bright red or orange-red line right at the edge of the mantle. This line widens at fairly regular intervals to give a pattern of spaced semi-circular spots around the mantle edge. The mantle is ovate with a semi-permanent fold about mid-way along each side giving the animal the appearance of having a thin 'waist'. The body is relatively high and the mantle overlap is relatively narrow. The gills are simple and arranged in a circle around the anus. There are a few large ovate opaque mantle glands arranged in a submarginal band.
