8 m depth, Kure Atoll, Hawaii, Aug. 1985, dorsal view of 19 mm and 26 mm specimens, Photo: S. Johnson (Brunckhorst, 1993: Plate 4 D).
Notes compiled from Brunckhorst, 1993:
Phyllidia scottjohnsoni can be distinguished by its white background with black spots, small tubercles and cream to white rhinophores. Phyllidia ocellata generally has black rings around its tubercles but it has a gold background colour and gold rhinophores. Phyllidia scottjohnsoni appears to be a small species in comparison to P. ocellata, Phyllidia tula , Phyllidia varicosa and Phyllidia elegans.Phyllidiopsis loricata (Bergh) is superficially similar to Phyllidia scottjohnsoni, however the former species is more elongate and it lacks black spots in the mid-dorsal region. Phyllidia scottjohnsoni has fewer (7-9) lamellae on the rhinophoral clavus than Phyllidiopsis loricata (16-19 fine lamellae). Phyllidia scottjohnsoni is flattened dorsoventrally to a greater extent than most other Phyllidia species.

This photo of Phyllidia scottjohnsoni was taken at Midway Atoll in a cave at 15m. They are quite common there but I've never seen one here in the main islands.

Yes I agree with your identification. It is an interesting find.
