Glossodoris ghanensis from Senegal

Dear Bill,
I spent 2 weeks diving in Dakar, Senegal and I was filled with wonder at the biodiversity of these waters. I will start my contribution with these nice chromodorids. I think it is Glossodoris edmundsi Cervera, Garcia-Gómez, & Ortea, 1989 and I'd like to have your confirmation.
I found these guys in only one diving site, but here they were in large numbers. But nevertheless, I didn't find any one laying eggs (and yet I saw many characteristic egg-ribbons).
These chromodorids are very difficult to photograph because their notum is very reflective. In first photos I had a large light spot instead of animals' mantle. So, I had to adapt my lighting to have better

I have recently discussed my views on G. edmundsi. Basically I think it is a colour form of Glossodoris ghanensis and your photos are a very useful addition to the evidence supporting that opinion. In particular, your upper photo is almost identical to one identified by Edmunds (1981: Fig 12B) as C. ghanensis. In your animals, like those described by Edmunds, the black pigment on the mantle is mainly restricted to scattered black diffuse spots.
