I agree it looks very like Hypselodoris bertschi. Its gills, with an ornage smudge midway and orange tips is identical to the photos of Hawaiian animals. It differs from Hypselodoris cf. maculosa, which has a deep orange band midway up each gill, and no orange tips, and has a blue band the mantle edge. It also agrees with H. bertschi in having small mantle glands packed together all along the edge, down each side of the mantle.
If it is confirmed to be H. bertschi it will be an interesting extension of its range, as it is at present known only from Hawaii.
