Kinda looks like a Tityus obscurus or possibly T.metuendus, but Ive only had a couple Tityus. I've unfortunately not had either of them in my collection yet. So just going off pics I've seen of both species. Definitely not T.asthenes though
No record of T. obscurus or T. metuendus. Very probable that it is in fact T. brazilae but Tityus is a huge genus with many, many species that are closely related. There are also many more that have not been described yet.
