Goniobranchus sp. 02 can be distinguished by the dark pink mantle with a red marginal band, followed by a yellow/orange band, and an opaque white band. The rhinophore clubs are orange with opaque white spots, the gills are translucent pinkish with opaque white spots.
It is Chromodoris sp. 22 in IPN at page 229:

It was posted on 27 Dec. 2010 at these websites as Chromodoris sp. B  Genus: Alder & Hancock, 1855,
then changed into Chromodoris sp. 02  Genus: Alder & Hancock, 1855,
for some genera, such as Trinchesia was the alphabet almost through. I had to change the distinguishing alphabetic character into a number. I have chosen 2-digit numbers, even though '01' looks a little bit stupid, and now is only the genus italic written.
I follow the recent article (published: 10 April 2012)

and move Chromodoris sp. 02 to the reerected ("rescued from synonymy") genus Goniobranchus  Pease, 1866, on which Rebecca and Terry state: "This clade includes all of the Indo-Pacific species of Chromodoris that are not part of the black-lined, planar egg mass clade, except Chromodoris alternata and Chromodoris ambiguus."
