Melanistic Chromodoris hamiltoni

Hi Bill,
Welcome back and best wishes to you.
While you have been off line I have found a lot of nudis I cant id and have queries on, but have resisted flooding you with requests, but unfortunately I cant resist it any longer, so I will be passing them on at a slow rate. This one I found fairly close to a Chromodoris hamiltoni, but it is different enough to query. It was actually collected for our national parks display aquarium and then returned to the reef 4 days later.

Locality:  Sodwana Bay, South Africa, Indian Ocean coast. Depth: 14 m. Length: 25 mm. Dec 2005. Coral reef. Photographer: Colin Ogden

Noted added 11 January 2007: This is most probably Hypselodoris regina. See message #19207.

Dear Colin,
It's a bit hard to be sure but I suspect it is either C. hamiltoni or C. quadricolor. In either case the black pigment is clearly in excess. I can see traces of blue in your photos so I don't think it is an unnamed black species.
Best wishes,
Bill Rudman
