The Scorpion Files - Vaejovidae

This is a large family with 10 genera and 146 species (until 1998). This family includes only species from North America (Southwestern Canada, the United States and Mexico) and Central America (Guatemala). Vaejovids are found in nearly every habitat, up to the Alpine tree-line (over 3,000 meters), though most are found in arid (to 70 m below sea level) and semi-arid habitats. Some species experience "winter-like conditions", and are cold adapted.

Several members of this family have been reported to occur frequently in captivity.

Many species of this family can deliver very painful stings, but they are not belived to be dangerous to healthy humans.

SPECIES FILES:
This list of genera and species is based on Fet et al.(2000). Subspecies are not included in the list. I try to update the list as additions and changes are published. * denotes changes after Fet et al. (2000). I will be grateful for information about new development in the taxonomy of this family.
