Concerning message #17545:

Hi Bill,
following the message from Francis and Pirjo, I thought you might be interested that we have the same Diaphorodoris here, and I have also been misidentifying it as a D. mitsuii. It is reasonably common here.

Locality: Sodwana Bay, 14 metres, South Africa, Indian, 24 APR 2007, reef. Length: 6 mm

Thanks Colin,

I am just a bit hesitant to positively identify it as D. mitsuii because of the position of the orange band around the mantle edge. Terry Gosliner records this species in his Nudibranchs of Southern Africa but although noting its similarity to D. mitsuii is unsure because of his animal's white background and the ridge on its foot. We now know that D. mitsuii has both these characters but what we don't yet know is if it can have the red-orange band right at the mantle edge.

Best wishes,
Bill Rudman
