The Mexican scorpion Centruroides hoffmanni Armas, 1996 is redescribed, based on adults of both sexes. It is readily diagnosed by its medium size, dark brown two-banded tergites and brown marbling on carapace, appendages and metasoma, pectinal tooth counts, the shape of the female basal plate of the pectines, development of metasomal carinae, and shape of the telson and subaculear tubercle. The geographical distribution of this species ranges from southeastern Oaxaca to southwestern Chiapas, Mexico. It was originally compared with Centruroides thorelli (Kraepelin, 1891), but actually it seems to be closely related to C. infamatus (C. L. Koch, 1845) and C. baergi Hoffmann, 1932.
