This animal would seem to be either a variety of Phyllidia coelestis or of P. picta. It matches neither of them exactly. This species is rare in the Marshalls, known from only two specimens found on the seaward reef at Kwajalein. Its coloration puts it into the group of nudibranchs similar to P. varicosa that might be Mullerian mimics.
This species lacks a black line on the bottom of the foot.
