Smeringurus vachoni
Vachon's Hairy Scorpion, Vachon's Sand Scorpion
Smeringurus vachoni is a small to medium-sized burrowing scorpion endemic to the southwestern United States and northwestern Mexico. Formerly classified in Paruroctonus, it was reassigned to Smeringurus based on morphological and genetic studies. This psammophilic (sand-dwelling) species constructs shallow burrows in loose sandy substrates and is primarily nocturnal. It is distinguished by its densely setose (hairy) pedipalps and metasoma, an adaptation for sensory function in sandy environments.
