This species is uncommon in the Marshall Islands, known from 8 to 10 specimens from Enewtak and Kwajalein Atolls. It is very similar to Goniobranchus albopustulosa and G. rufomaculata and we suspect all three of these may be variations of a single species. Like the other two, it typically lives under rocks on lagoon reefs and pinnacles at depths of 5 to 10m.
The specimen below was found on a Kwajalein Atoll lagoon pinnacle under a rock in about 8m of water on 30 August 2009.
