of the eastern population was lower than that of the western population. We analyzed linear and ratio body measurements with parametric and nonparametric statistics to test species limits. These analyses indicated that all putative populations of C. baergi are significantly similar, suggesting that they may represent a single species. Unexpectedly, the population of scorpions in the center of the study area, Suchixtlahuaca, previously identified as C. baergi, showed significant morphological and venom composition differences. We provided empirical evidence of an abrupt change of highly toxic peptides around the 98th meridian that limits populations of Centruroides baergi to the east of Mexico.
