Centruroides granosus (Thorell, 1876) is redescribed based on several specimens of both sexes from Panama. We demonstrate that the original description of this species was based on an immature (subadult) male, which is herein designated as the lectotype. We conclude that Centrurus granosus simplex Thorell, 1876 is a senior synonym of Centruroides testaceus arubensis (Bakker, 1963), and elevate it to species level: Centruroides simplex (Thorell, 1876), comb. nov.
