Determined by Salvador Vitanza
Confirmed by Steven Wang who said: “One of the most distinctive southwest Pheidole, for its large size and very long and sharp propodeal spines on both the majors and the minors. These are one of the most basal Pheidole – most “higher” Pheidole are much smaller ants.”
