No common name that I know of, its always good to go by scientific names though so you don't get mixed up in the confusion of common names!
My H. hottentotta was a very beautiful scorpion, you have to be careful with scorpions like this though because their venom is more potent than the more popular larger species of scorpions. I don't believe the Hottentottas have been known to be lethal to humans, but you must use extreme caution when dealing with them.
