I'm not sure you'd be able to tell the difference from those pics since those subspecies are so similar, but these two links have info on the exact scale/pattern layout of the two species, so they might help you figure out which they are. Color isn't always the best way to identify, since there can be pretty wide color variation even within subspecies.
