Identification

Distinguished from other Phidippus by geographic range and elevation preference (5,000–7,000 feet). Males identified by pale orange coloration; females require careful comparison with similar Phidippus. Separated from P. audax and P. octopunctatus by color pattern and . Ten Phidippus species occur in the Pikes Peak region, necessitating detailed examination for definitive identification.
