Same genus, different locales

2 different Arbanitis trapdoors, both unidentified. The brown one is from where I live and the black one is from more of a rainforesty area about 70 minutes away. The black one is extremely aggressive and most attempts at opening the lid for feeding result in an instant threat posture
The black one also has far more vibrant gold on its head, which once again is only visible when viewed from the front or directly above. I believe this is counter shading for when the spider is wandering, so that from behind where the spider is vulnerable it is less visible, and when in front of a potential predator where the spider can face them head on, the gold is a flashy warning. Only other thing I can think of is its to improve visibility for mates considering their terrible eyesight, but that would depend on just how terrible that eyesight is
