Dear Bill
Here is one more shot of the one you labeled Hypselodoris maridadilus on October 28, 2000
I think it looks like Hypselodoris centuculus Yonow, 1994. Is this id ok? Is this species valid?

Dear Erwin,
As I said in reply to Valda Fraser's message, your animal does look identical to Nathalie Yonow's photo of H. centunculus. I had previously thought that H. centunculus was most probably a colour variant of H. maridadilus [see comments on Clay Bryce's message], but Gosliner & Johnson (1999) have examined the anatomy of one of Yonow's specimens and conclude from that it is identical to Hypselodoris whitei in features of the radula and mantle glands. The white tipped rhinophores are also found in H. whitei. So in brief, your animal does look like H. centunculus, but that species is in fact a synonym of the much older H. whitei.
Best wishes,
Bill Rudman
