Concerning message #9861:

Dear Bill

In an earlier message, you tell us that your C. mandapamensis photos from New Caledonia failed. I send you what I believe is a Chromodoris mandapamensis. I hope they can help us to make sense between C. mandapamensis, C. burni and C. striatella...

Locality: Noumea, 10 m, New Caledonia, Pacific Ocean, 2007, muddy. Length: 3 cm. Photographer: Jean-François Hervé.

Kind regards
Jean-François Hervé

Dear Jean-François,

It was not my photos of C. mandapamensis that failed but photos of animals from New Caledonia which had both black lines and black spots and in my opinion show that C. mandapamensis is a spotted form of C. striatella. In fact Robert Sozzani's photo in the message you refer to shows exactly this.

I am placing your message with C. mandapamensis, but at the risk of sounding like a squeaky wheel, I suspect it is a form of C. striatella. One interesting feature in your photo is the bluish sponge in the foreground. It seems to be part of a larger colony partly covered by algae or detritus. Unfortunately I can't see enough detail to be sure of its identity, and of course we can't even be sure it is feeding, but I think it is worth drawing attention to it in case we later find this species feeding on the same sponge.

Best wishes,
Bill Rudman
