I have some difficulties identifying these blue dorids from Dakar, Senegal. They seem to me rather different from usual Hypselodoris tricolor. Could it be Hypselodoris gasconi Ortea, 1996 ?
These photos were taken by Patrice Petit de Voize on the Tacoma wreck in April 1999, at a depth of 10m.

Dear Marina & Patrice,
I think we all have problems with the 'blue chromodorids' of the Mediterranean and nearby Atlantic coasts. I guess that's what makes them so interesting. Hypselodoris gasconi, apart from only being known from the Mediterranean, has a white line along the edge of each gill and a white line along the posterior midline of the rhinophore club. Having said that, the only way to be 100% sure would be to check its anatomy. I am pretty sure Patrice's photos are of Mexichromis francoisae which was first described from Senegal and later (Ortea, 1988) from the Cape Verde Archipelago.
