Despite the three banded rhinophores, I think these fall more into Hypselodoris maculosa than they do H. decorata. There are also similar animals that I think are different species, although they could be and are usually considered variations of this one. The similar species on these pages are here. Our Marshall Islands pages provide additional photos and information about H. decorata and H. maculosa from that area.
