The first specimen of this species was found on a Kwajalein lagoon reef under a rock on 5 July 2009. It was at a depth of 6m and measured 11mm. It differs from similar Kwajalein species such as Gymnodoris subornata by its gills, which are set in a complete circle. Specimens from Vanuatu are figured in Gosliner et al (2018) as Gymnodoris sp. 46.
The forked tail on the single specimen is probably a deformity.
The specimen below found at Ailinglaplap Atoll by Stan Jazwinski would appear to be the same although that requires confirmation.
The specimen below also would appear to be the same species, although that needs to be verified. It was found on 30 July 2012 on a shallow lagoon reef.
