Check out this study: http://www.larrea-plot.com/Lizard.htm

Looks like Pogo's would work out fine. Probably Californicus or Rugosus as long as they are large enough.

"In this study the two Phrynosoma species are united in their high usage of Po. imberbiculus . This ant was present in 85-89% of the fecal pellets of Pm and 92-100% of those of Pc; Po. imberbiculus ranked 1st in importance by weight in all size classes of both Phrynosoma, except the largest 66-108 mm Pc . In their feedings the dominance of Po. imberbiculus is abruptly replaced by that of the larger Po. desertorum (IV numbers = 0 500, wt = 0.713, Table 4). This may be an important adaptation for Pc since it achieves sexual maturity at these sizes, and large ants would more effectively supply the additional nutrients needed for
reproduction than a greater number of smaller ants. By contrast, Pm, which are sexually mature at 53-65 mm, are feeding on the same ants as Pc of that size. "
