A new scorpion species, Vaejovis stetsoni sp. n. is described from Galiuro Mountains, Graham County, Arizona. This is the smallest species of the “vorhiesi” group discovered so far, most similar to V. brysoni Ayrey & Webber. The pedipalp fixed finger has five ID denticles and the movable finger has six, like in most other southern Arizona Vaejovis. The most unique characteristics of this species are its small size (18.35 mm) and a large subaculear tubercle.
