Hi Bill!
Please find attached two photos.
Upper: Flinders Reef, north of Moreton Island, Queensland, Australia. 26m depth Lower: off Mooloolaba, Queensland, Australia 18m depth.

Are either or both these Glossodoris cincta?
Thanks for you help.

Dear Gary,
Your upper photo is the typical West Pacific colour form of Glossodoris cincta. If you look at the photos on the species Fact Sheet you will see I have identified a 'Philippines - Indonesia colour form' which is very similar to your lower photo. When I examined the anatomy of thses animals I could find no consistent differences between the 3 possible 'colour forms' so decided to leave them as one species, each colour form occurring in a specific geographic area. I am not sure if your animal is a rather lost 'Philippines - Indonesia colour form' or whether it is something different. I guess it is best to think of it as 'Glossodoris cf. cincta'. All we can do at this stage is to let more material accumulate until a clearer pattern emerges. It is an interesting animal.
Best wishes
Bill Rudman
