That looks like a P. barbata to me. The spines on top of the head are very similar to those of P. m. minor. It’s the beard and the spines along the edge of the body that are different. Of course adult P. barbata differ in numerous other ways. If the photo renders its true colours, the black beard that is developing is symptomatic of a male. The black throat is typical and the mouth lining and gums will gradually develop a deep yellow colour to them as it matures.
I should have qualified what I said about picking up wild P. barbata. You can get within about two or three metres of an adult and they will bolt off into the undergrowth and suddenly stop. The hatchlings tend to rely more on camouflage. Once they get a bit bigger they too will bolt off but only if there is protective cover to jump into. If they are on an exposed branch with say nothing but dirt underneath, they will tough it out. But if you touch them, they will jump and run. An adult in a tree will move away from you but in my experience they are reluctant to jump.
To not have the animal struggle when picked up is not normal. At the very least you should cop a full display of the beard and I can assure you from experience that they are more than capable of leaving decent scratch marks. I can only wonder if it was still cold and torpid or possibly ill or, as I suggested, previously captive.
