Thorunna? sp. 1 from Western Australia
Originally described from Japan, the animal illustrated above from Hong Kong looks very similar to the many reports from Japan. In Japanese specimens the purple submarginal line is broken into a string of diffuse spots or patches much like in the Thailand specimen. I consider the Western Australian specimens to represent a colour form rather than a separate species as their internal anatomy is identical to that of the Hong Kong and Japanese specimens. See messages below for discussion of the Thailand specimen.
