Dear Bill,
Attached are photos of a similar animal to the photos sent by David Mullins, this one find at Heron Island [Great Barrier Reef]. I have also been calling this animal Hoplodoris nodulosa. It was found intertidally at the reef crest under a dead coral boulder.
Locality: Heron Island, Intertidal, Queensland, Australia, Pacific Ocean, 24 November 2007, Intertidal. Length: 50 mm. Photographer: Julie Marshall.
Best wishes,
Julie Marshall

Dear Julie,
The animal in David Mullins' photo had a distinct colour band down the centre of the mantle and lacked the whitish speckling we can see at the top of each tubercle in your animal. Your animal also lacks the whitish tips to the gill leaflets. I suspect these are the type of differences we are going to find will be useful in separating these species on external features. On those grounds I would identify your animal as H. grandiflora.
It's possible that some of my earlier identifications are wrong, but I hope I made my 'hesitation' clear in those messages. We obviously have more to do with this genus.
Best wishes,
Bill Rudman
