Pheidole boliviana

This species occurs in wet to moist forest habitats, from sea level to 800m elevation. Collections have been from second growth vegetation and a coffee plantation. Nests are in the low arboreal zone, within a meter or two of the ground but not in the leaf litter on the forest floor. Nests have been found in a small diameter dead stick and under loose bark of larger rotting trees. (Longino 2009)
