Mexichromis festiva from Sydney

From: Erik Schloegl

Dear Bill,
I found this one, which I think is Mexichromis festiva, on rocky reef at a Sydney dive site called "The Colours" (just south of the entrance to Sydney Harbour)[New South Wales, Australia] on 18 February, 2001. The depth was approximately 25m, the water temperature was 22 C.

Best regards,

Dear Erik,
Yes this is Mexichromis festiva. This pretty little chromodorid was first described from Sydney in 1864 by George Angas, who was for a time employed at the Australian Museum. It was one of the first nudibranchs described from Australia.
Best wishes,
Bill Rudman
