Taxonomic history

Senior synonym of Pheidole petersoni: Longino, 2009 PDF: 31.

    Americas: Costa Rica, Nicaragua
  Biogeographic regions (According to curated Bioregion/Taxon lists):
    Neotropical

Distribution Notes:

Nicaragua, Costa Rica. Costa Rica: widespread in wet forest areas, to 2000m in Braulio Carrillo, to 800m in Penas Blancas.

Biology:

This species occurs in wet forest habitats, from sea level to 1400m elevation. Nests are in rotten wood or dead sticks on or near the forest floor. Workers are occasionally collected in Winkler or Berlese samples, but have not been collected at baits.

Notes:

Additional collections of this species have blurred the distinction between erratilis and petersoni. There appears to be one species with variable sculpture on the pronotum. The images on this page are from the same nest series as the holotype of erratilis. Click here to see the old petersoni page, which contains images from the nest series of the holotype of petersoni.
