A new scorpion species, Vaejovis halli sp. nov., is described. This relatively small, brown new species is found on Mount Ord in the Mazatzal Mountains along the Mogollon Rim of northern Arizona. The new species appears most similar to V. vorhiesi Stahnke and V. deboerae Ayrey. The most distinguishing characteristic of this new species is the number of inner denticles (ID) found on the pedipalp fingers with six on the movable finger and usually five on the fixed finger, which more closely correlates with Vaejovis species from the mountains of southern Arizona rather than those geographically closer in northern Arizona.
