Okay, we are getting somewhere, comparing morphometrics. Yes, the chela size, what can we say about other structures.There are diff sizes with Hadogenes species, H. paucidens generally smaller than troglodytes, still a nice size scorp though. Hard for me to tell which are adults with Hadogenes if they have one more molt to go. The first posted could be adult going by the thick chela. BAM1082's looks like a fat juv to me, doesn't look premolt to me though, just fat. I like the rock/slat you used there BAM.
