Geographic Range

Biology

This species inhabits mature wet forest. It appears to be both arboreal and terrestrial, occurring commonly in forest floor leaf litter and in the canopy. Nests are in irregular cavities in dead wood. Wilson (2005) observed that P. nebulosa  HNS  and two other species of small Pheidole  HNS  ( flavens  HNS  and bilimeki  HNS  ) frequently prey on oribatid mites in the leaf litter.

Comments

Pheidole nebulosa  HNS  has a highly distinctive feature in the major workers: there is a single large rounded medial tooth on the hypostomal margin and no inner hypostomal teeth. All other Central American Pheidole  HNS  in the same size range and with similar sculptural features have inner hypostomal teeth. The only difference between the types of P. scabriventris  HNS  and P. nebulosa  HNS  is color. The former is red brown instead of yellow.
