Oh, strange that I found a bazillion papers about venom research then. Depends on what you feed Google, try Tityus stigmurus venom...I ran a google search already. I mostly found articles from venomlist(2 sting reports) and AB.
Both of which were not very informative. BrianS told me about his incident a year or so ago. I know he said it hurt...but aside from that not much else.
