Dear hp,
This animal is very close to the colour form or 'species' which is known as Thuridilla bayeri (Marcus, 1965). However that colour form usually has a white band on the rhinophores below the orange tip. Clearly there is still some work to do on this colour group. Photos like this are a great help in building up more information on colour patterns.
Best wishes,
Bill Rudman
