FIGURE 3. Bivariate plots for workers: (A) maximum eye diameter versus head width, (B) ocular index versus head width, and (C) malar ratio versus head width (n = 63 for P. magnacanthus Cole, n = 59 for P. hoelldobleri Johnson, Overson & Moreau, plus 16 PARATYPE workers of P. magnacanthus that do not belong to the latter species [see text], n = 25 for P. mohavensis Johnson). Non-type workers were selected to represent the geographic range of each species.
