Gymnodoris rubropapulosa (Bergh, 1905)

These are probably Gymnodoris rubropapulosa; there are photos on the Sea Slug Forum where the orange pustulose dots are replaced by rings, more like the specimens below. There is even a trace of the ring pattern in specimens we've seen from the Marshall Islands. It would probably take anatomical dissections or DNA testing to confirm they are all the same.
