Serradigitus miscionei, commonly known as the Walnut Gulch scorpion, is a rare species of scorpion found only in southern Arizona, United States.[1] This species is one of three Serradigitus species found in Arizona.
Serradigitus miscionei is a small reddish, brown scorpion, adult females reach an average length of only 25mm. It was discovered while searching for lizards on the walls of a wash that empties into the San Pedro River. It was described on the first of February 2011 by Richard Ayrey.[1]
Serradigitus miscionei seems to prefer vertical sand substrate, which is not commonly seen in other scorpion species.[1] Like most scorpions, Serradigitus miscionei feeds primarily on small invertebrates. Its venom is not known to be medically significant to humans, dogs or other mammals.[1]
