A dated molecular phylogeny of the southernmost Americanspecies of family Buthidae based on two nuclear and two mitochondrial genes ispresented. Based on this study, analyzed species of subgenus Tityus (Archaeotityus) are neithersister to the remaining species of the genus Tityus, nor are they closely related with the New Worldmicrobuthids with decreasing neobothriotaxy. Analyzed species of subgenus Tityus do not form a monophyletic group.We present a hypothesis about thepatterns of historical colonization processes of the family Buthidae in southern South America, as well as theirprobable relation with the geological events that modified the ecologicalconditions in the region, comparing it with the diversification processes ofother epigean groups from the area.
