Very debatable. Until I see something official and conclusive, I stick with the G. grandidieri. There is so much confusion with all the hissers and thier taxonomy that may never get cleared up.Well, I have a few of these little guys I received a while ago in a trade. I thought that they were G. grandideri, but after looking over some ominous forum posts I'm not entirely sure what they are. Are they P. vanwarebecki or G. portentosa?
