Pheidole borgmeieri

This species nests in rotting wood in rainforests. (Wilson 2003)

Identification
A small member of the flavens group, most similar to Pheidole nana of Brazil, differing from it and other species of the group as follows.

Major: all of head except frontal triangle and mid-clypeus covered by parallel longitudinal carinulae; the carinulae passing between the eyes and antennal fossae curve inward (mesad) as they approach the occiput, such that those from the two sides of the head meet at the midline near the occipital border; profile of promesonotum in side view forms a smooth, near-perfect semicircle; humerus extended as a prominent lobe in dorsal-oblique view; almost all of mesosoma, waist, and gaster smooth and shiny.

Minor: almost all of the body smooth and shiny; propodeal spines reduced to denticles. (Wilson 2003)

Distribution
Known from São Paulo state, Brazil. (Wilson 2003)
