Has the Glossodoris mentioned in Gosliner, T. 1987 NUDIBRANCHS OF SOUTHERN AFRICA. Sea Challengers,- Glossodoris sp 1, page 84) been named? It looks the same as the specimen Glossodoris undaurum(page 227) in Debelius, H. 1996. This nudibranch occurs in the area where I live.
Locality: South Coast KwaZulu/Natal - SOUTH AFRICA. Near Port Shepstone, Rocky reef, 15m, October 1999. Size: 66mm
Yes I think your animal is Glossodoris undaurum. The white patches are not that clear in the photo I have posted above, and the yellow border in your photo doesn't seem as distinctive.
A comparison of the anatomy of the two would be required to be certain, but it certainly looks as thought this species is on both sides of the Indian Ocean. Terry Gosliner may be able to confirm this for us.
