Thanks for the reply Michiel.
I didn't include the a. bicolor. Just wondering what androctonus species this is. Do you have any idea? Yes i also notice the mycosis on the leg, hoping that it stops spreading.
I can't help on the ID but the black spot may only be an injury. Injuries usually turn black. I don't know if there have been studies but it's been my speculation that the black color caused by mycosis is not the color of the fungus but is the color of the damage it causes, whether it is caused by a fungus or from a more mechanical source, it generally turns black. Mycosis usually starts around joints and normally shows up symmetrically on the joints at first. Michiel have you come across any studies of the color of the fungus that causes mycosis compared to the color of simple injury to a scorpion? I do not see this brought up often and have wondered about it.
