From Wilson (2003): A member of the “jujuyensis complex” of the larger fallax group, comprising Pheidole araneoides, Pheidole cuevasi, Pheidole durionei, Pheidole jujuyensis, Pheidole kugleri, Pheidole leonina, Pheidole leptina, Pheidole lucretii, Pheidole lupus, Pheidole paraensis, Pheidole punctithorax, Pheidole tijucana, Pheidole wallacei and Pheidole wolfringi.
