Hi Bill.
Please can you help with this one. I found 2 of them faily close together and at first thought that they were Hypselodoris carnea, but when I downloaded I couldnt ID them. I cant find their ID in any of my books and would appreciate your help.

Locality: Sodwana Bay, 18 metres, South Africa, Indian, 12 Jan 2010, reef. Length: 50mm. Photographer: Colin Ogden.

Dear Colin,

This is Hypselodoris nigrolineata. Apart from Eliot's description in 1904 and my rediscovery of it in 1975 in East Africa, I think this record of yours is the third animal which I would confidently identify as this species. We have another on the Forum from Reunion, which I have hesitantly identified as H. nigrolineata, but the much thinner black lines make me a bit doubtful.

Best wishes,
Bill Rudman
