Geitodoris sticta

Miller, 1996

Chandy de Wit New comer to my favourite local Nudi site in Kwinana Western Australia 4cm length @ 4m depth... Maybe Platydoris? The gills are cream coloured...

Gary Cobb I wonder if this is Geitodoris sticta! Platydoris species tend to have a smooth mantle.

Chandy de Wit Thank you Gary Cobb, don't know how you do it :)

Gary Cobb It all done with magic and mirrors! Seriously tho I have spent the last 11 years looking at photos and specimens where I can compare anatomy and come up with the best ID. Thanks.

Chris Cunnold Wow Chandy , this might be a first for that location. I've never heard of it around Perth.

Gary Cobb Nice news Chris!

Chandy de Wit Great news Chris Cunnold, I saw two on a night dive @ the Grain Terminal last week and haven't seen any since? Maybe transported in ship ballast water?

Brendan Oonk Judging by the star shaped acid glands, I'm sure it is Geitodoris. I don't know the species of Geitodoris you got over there... In the Netherlands, a nudi like this, would have been called G.planata, the only one we get.. I'm not able to distiguis between the species from this picture.

Brendan Oonk Gary can you explane to me why you call this G.sticta? Or is it simply by distribution?

Gary Cobb We only have 3 species of the genus Geitodoris in the Australia / New Zealand region that are known. This photo matches Geitodoris sticta. And yes distribution has a bit to say when trying to ID species. DNA would tell us for sure but in the game of identification we can ony go by what we presently know.
