Pheidole texana

P. texana is evidently a rare species. Wheeler (1903c) discovered only four colonies over many years’ collecting, and all in Travis County, Texas; all were in grassland, nesting in open soil, with the entrances surmounted by small mounds about 10 cm in diameter. During their intensive collecting in western Texas, Moody and Francke (1982) found only two colonies, nesting in open, fully exposed clayey loam. (Wilson 2003)

Identification
See the description in the nomenclature section.

Distribution
Known from the type locality, as well as Sutton and Uvalde Counties in western Texas. (Wilson 2003)

This taxon was described from the United States.
