that looks like an assassin bug - and if it is - most are toxic - we have the huge caug wheel assassin's - I have even stopped putting my chams out that are not in screen cages because I have seen so many lately and fear they will eat one
I forget the name of the species but yes stay away. They can be used right after they molt but once the exo skeleton is hardened they can give a painful stick. Also there isn't much to them. The are mostly hard exo skeleton.
