Another tough one. I think this is more likely Sclerodoris tuberculata, although I don't see the characteristic irregular crater-like protrusion middorsally. But looking through my photos, I see a couple where the crater is not evident, yet they are clearly that species.

This has all the external characteristics of Aldisa pikokai including color, number and position of the dorsal craters, dark spots within the craters, crisscrossing network of ridges over the rest of the dorsum. Of course it would take internal examination to be sure, but I think it would be safe to call it pikokai. Egypt is quite a range extension from Hawaii and the Marshall Islands.
