Pheidole diversipilosa

According to Stefan Cover (personal communication), diversipilosa is common at mid-elevations (1050–1900 m), favoring oak-pine-juniper forests, especially those in creek valleys, where it nests under rocks and in open soil. Colonies have single queens and large populations, which can exceed 1000 workers. Seed caches have been found in some nests. (Wilson 2003)

Nomenclature

 *  diversipilosa. Pheidole crassicornis var. diversipilosa Wheeler, W.M. 1908e: 467 (s.w.q.) U.S.A. Junior synonym of crassicornis: Creighton, 1950a: 175; Gregg, 1959: 20. Revived from synonymy and raised to species: Naves, 1985: 61. See also: Wilson, 2003: 153.

Description
From Wilson (2003): Very close to Pheidole crassicornis from which it differs in the major by abundant pilosity on the mesosoma and gaster, and Pheidole tetra, from which it differs in the major by the much shorter pilosity on the first gastral tergite and by sparseness or absence of pilosity on the waist and occiput.

Also resembles Pheidole pilosior and Pheidole porcula in various traits as depicted.
