Gymnodoris okinawae Baba, 1936

Gymnodoris okinawae is characterised by a gill that forms a complete circle around the anal papilla, orange spots, dashes and lines plus opaque white pustules on the notum. The rhinophores have a pale brown club.

Note that Gymnodoris okinawae is not the only Gymnodoris with opaque white pustules on the notum.

We previously had an image here of a specimen of our now, Gymnodoris sp. 29 = Gymnodoris sp. 3 of NSSI, 2018. Very similar to Gymnodoris okinawae but the gill circle is incomplete posteriorly. Altered March 2023.
