These scorpions are most commonly found in Mexico, especially in arid and semi-arid habitats. Small to medium-sized scorpions, typically a few centimetres long. Usually light to medium brown, tan, or gray, often with darker mottling that helps them blend into rocky or sandy environments. Their venom is considered mild and not medically significant to humans, usually causing effects similar to a bee or wasp sting (localized pain or irritation). Nocturnal hunters, emerging at night to prey on insects and other small arthropods.
