Maby WW can this!?
Because, within the discription of Naja nubiae and seperation from pallida, he must have seen manny ,,pallida´s´´ and other Najas from the distribution area to seperate the nubiae from pallida. And when there is a typical pattern local form, I´sure he will know this. BTW: For me it is the first time that I see such a Dot on a head of an pallida... Looks interessting!
