Maldives: 15 mm, Banana Reef, North Malé Atoll, 12 m depth, 19 November 1995, leg. SG Buttress & RC Anderson, and photos of another individual, RCA. - Mayotte: photographs of numerous individuals http://seaslugs.free.fr/nudibranche/a_intro.htm.

Description/Remarks.

The small specimen illustrated in Plate 43 was very dark brown, with a few large pustules distributed centrally and marginally, and speckled greenish-yellow gills and rhinophores: Maldives specimens are usually darker brown than individuals from other localities. It is noteworthy that the only Indian Ocean specimens available are once again from the Maldive Islands. Currently, the only photographic records from anywhere else in the Indian Ocean are from Mayotte (http://seaslugs.free.fr/nudibranche/a_intro.htm), although there are other internet photos of this Indo-West Pacific species from Tanzania and South Africa ( Sea Slug Forum) and the Maldives, Kenya, and Madagascar (NudiPixel).
