This species is a bit similar to Cuthona ornata Baba, 1937, but differs enough to keep it separate. It is known from the Marshalls from two specimens, one from Enewetak and the other found on the windward seaward reef of Kwajalein Atoll. The latter specimen was shallow, at a depth of 3 meters in the groove and spur system of the atoll's outer reef. This area is extremely surgy most of the time. It is a wonder that this 11mm nudibranch would have the strength to hang on in the surge of the waves crashing above. Specimens are also reported from Guam and southern Japan in Gosliner et al (2008).
