This looks like it could be Durvilledoris similaris. This is one of a pair found at Utirik Atoll, Marshall Islands, back in 1983. Haven't seen any since. The two specimens measured 9 and 10 mm.

Certainly looks like it. If so, it is a much more colourful one than I have seen. It also looks a bit like Noumea norba
