From Wikipedia, the free encyclopedia:
Superstitionia donensis is a species of scorpion, the only species in the genus Superstitionia and the family Superstitioniidae.
This species was discovered in Arizona in 1940 by H.L Stahnke and predominately is found in western New Mexico, Arizona, extreme southern Nevada, and southern California in the United States. It is also found in Baja California, Baja California Sur, and Sonora in Mexico.
The genus name refers to the Superstition Mountains where the species was first discovered. S. donensis is normally found living in mountain terrain and under rocks or near plants in desert terrain.
This is an unusual group of scorpions because all members except S. donensis are specifically adapted for living in caves. The scorpions in the family Superstitioniidae have no color pigmentation and no lateral eyes, except for this species. This subspecies is dark in color ranging from tannish to dark brown. It is a shiny and spotted scorpion. This scorpion reaches a length of 30 mm (1.18 inches) in adults.
