Paradoris dubia from New South Wales

Concerning message #19604:

Dear Bill,
Nerida Wilson's sharp eyes found this nudibranch at the Pipeline. The characteristics that struck us the most were the white circles on the body, some like a child's drawing of a sun with spokes, and the brown spots on the side of the foot. Once Nerida saw the photos she suggested it might be a pale Paradoris dubia. The circles fit with your description of the glands but the rhinophores seem a little pale in comparison to the specimens on the fact sheet. There is one previous message with paler rhinophores similar to this one. It is the first time we have seen this in the Port Stephens area.

Locality: The Pipeline, Port Stephens, 8 metres, New South Wales, Australia, Pacific, 12 April 2007, Silty sand, scattered sponges, ascidians and soft corals. Length: 30 mm approximately. Photographer: Leanne & David Atkinson.

Can you confirm its identity?
Thanks for your help,
Leanne & David Atkinson

Dear Leanne & David,
Your description of  'a child's drawing of a sun with spokes' fits my drawing [message #19148] of these glands. I am sure your animal is Paradoris dubia which takes it a bit further up the east coast than it has been reported before.

Best wishes,
Bill Rudman
