Goniobranchus albopustulosus (Pease, 1860)

This species is either rare or uncommon in the Marshall Islands, depending on how you want to break down the species. Goniobranchus albopustulosa is very similar to G. rufomaculatus, G. alius, and G. albopurpureus. There appears to be overlap between some of these animals, and our impression is that at least the first three may be variations of one species. We think G. albopurpureus is probably different. The typical G. albopustulosus form is known in the Marshalls from only a few specimens, most of them from Enewetak Atoll, where both of the photos below were taken. The top one is sort of the standard G. albopustulosus color form, with low white pustules on a yellowish orange background and a marginal band of purple that varies in intensity. It looks a lot like specimens we observed in Hawaii.
