Chromodoris from the Solomon Islands

From: Scott Johnson

Hi Bill,

The attached Chromodoris was photographed at Guadalcanal, Solomon Islands, on a trip I made down there in 1994. The closest I could come to an ID is Chromodoris hamiltoni, which would be a considerable range extension from the eastern Indian Ocean. However, there is also some similarity to the Chromodoris cf strigata photographed by Bruce Potter, also from the Solomons.

Locality:  Aruliho, Guadalcanal Island, Solomon Is. Depth: 12 m. Length: 15 mm. 8 April 1994. Exposed in ledge. Photographer: Scott Johnson.

Thanks Scott,
I agree it fits the 'species' I am calling Chromodoris cf. strigata. I am not sure if it is a colour form of true Chromodoris strigata or not. I have found that sometimes parts of the black lines in some chromodorids are replaced by orange in some animals. I guess it is a chemical malfunction somwhere. That is why I still tend to think this may be a form of C. strigata, although we now have 3 individuals all fairly consistent in their colour pattern.
Best wishes,
Bill Rudman
