Greater short-horned lizard its close relative the pygmy short-horned lizard ("Phrynosoma douglasii" ), which has the same basic body type consisting of small pointed scales around the head and back. Until recent mitochondrial DNA evidence, "P. hernandesi" was considered to be the same species as "P. douglasii". They are now considered distinct species with the pygmy short-horned lizard ("P. douglasii" ) occupying the northwest portion of the United States and extreme southern British Columbia. When placed together the two are easily distinguished at full size, the pygmy short-horned lizard being much smaller. "P. hernandesi" is a highly variable species with different geographic populations
