Pheidole goeldii chloe

Longino (1997). ) reports striaticeps which as noted, may include both true striaticeps and chloe, from mature rainforest, nesting beneath the bark of rotten stumps and logs. (Wilson 2003)

Identification
See the description in the nomenclature section.

Distribution
Costa Rica and Mexico. Longino (1997) does not distinguish this species from striaticeps, although the two appear to be different. He reports triaticeps, which may include both species, from the Atlantic slope to 500 m and Pacific lowlands of Costa Rica. (Wilson 2003)

Distribution based on Regional Taxon Lists
Neotropical Region: Costa Rica, Mexico.
