Pretty similar are:
Goniobranchus cf. albopustulosus which is a 9 mm juvenile specimen, and differs by the colour of the gills: red-brown with white spots or edges, and by the submarginal violet spots. It is most possibly an undescribed species of Goniobranchus or Goniobranchus.
Goniobranchus vibratus which has a yellow mantle with white pustules and violet patches at the mantle margin. It differs by the gills and rhinophores, both of them are white and dark purple tipped.
This species is in older publications as Chromodoris albopustulosa (Pease, 1860) [Doris],
R.F. Johnson & Gosliner. (2012) moved it to the reerected ("rescued from synonymy") genus Goniobranchus Pease, 1866.
