Interesting closeup on the eyes -- this is the first species I've noticed more than three pairs of lateral eyes.

i noticed that, finishing the pics in photoshop. i took detailed pics today and checked some of my other scorpions. i counted from two to five lateral eye pairs. some parabuthus have three regular sized and two smaller pairs. a.australis: 4 pairs, some centruroides: 2 pairs. i may be wrong, it's kind of hard to spot on a moving scorpion. on dark species it's impossible to see without a microscope.
