Specimen labels

Longino (1997) reports striaticeps, which may include both true striaticeps and Pheidole chloe, from mature rainforest, nesting under the bark of rotting stumps and logs. At Cuzco Amazónico, near Puerto Maldonado, Stefan Cover and John E. Tobin found a colony in a gap within mature rainforest, beneath the bark of a rotten but still hard log. (Wilson 2003)

Identification

See the description in the nomenclature section.

Distribution

Mexico (almost certainly tropical Mexico), Honduras, Costa Rica, and Amazonian Peru. Longino (1997). does not distinguish this species from Pheidole chloe, although the two are different. He reports Pheidole striaticeps, which may include both species, from the Atlantic slope to 500 m and Pacific lowlands of Costa Rica. (Wilson 2003)
