SIMILAR SPECIES:

No other buthid scorpions naturally occur in California. At least two species, however, have been intercepted in produce from Mexico and Central America: Centruroides limpidus and Centruroides limbatus. Neither species has become established.

DISTRIBUTION:

In the United States, this species is found in Arizona, California, New Mexico, and Nevada. In Mexico, it occurs in Baja California, Baja California Sur, and Sonora. California records and a distribution map will eventually be included in this site.

COMMENTS:

This is the most medically significant species of scorpion in California.
