Tityus stigmurus is a species of scorpion from the family Buthidae that can be found in Brazil.

It is suggested that Shelfordella lateralis is a good species of cockroaches, that are abundant worldwide.

Aside from being abundant they also are the easiest prey, since they don't hide, and the scorpion can easily eat them.

This species is predominantly found in the northeastern parts of Brazil, especially in the Caatinga region.
