1st Vaejovis spinigerus in think the name was revised to (Hoffmannius spinigerus) or it is a Vaejovis sp - stripe-tailed scorpion or the "devil" scorpion
2nd Centruroides vittatus- striped bark scorpion.
To be honest though common names mean nothing there are many different common names for scorpions and makes it difficult for people to know exactly what sp you are referring to. For example when someone say "Fat tail" there are so many different sp that scorpion could be from A. australis to P. transvaalicus it could refer to a large number of scorpions in the Buthidae. Scientific names are universal they do not change unless there is a scientific revision. It is still the same name if you speak a different langue its the same in german, english, spanish, french, russian. It will always be a constant.
