Pheidole perpusilla Emery 1894

This species occurs in wet climate areas, from sea level to 1200m elevation. In mature forest areas it is a common species under epiphytes in the canopy, although its minute size makes it easy to overlook. It also occurs on trees in synanthropic habitats such as coffee farms and city parks.

Southern Mexico to Amazonian Brazil. Costa Rica: Atlantic and southern Pacific lowlands.

Ho descritto questa formica come sottospecie di Ph. flavens trascurando di contare gli articoli delie antenne. Ora mi accorgo che queste constano di soli 10 articoli, tanto nel soldato quanto nell'operaja e nella feminina. Per questo carattere, la Ph. perpusilla differisce da tutte le congeneri finora note e deve essere considerata come specie a se.
