In Costa Rica, Longino (1997). found a colony nesting in a flat cavity beneath loose bark on top of a rotten log; and in Panama, Alfred E. Emerson found it in small cavities inside a rotten log. (Wilson 2003)

DIAGNOSIS A very distinctive little species similar to Pheidole asperithorax, Pheidole exigua, Pheidole flavens, Pheidole nuculiceps and Pheidole pholeops, but easily recognized as follows.

Major: in side view, promesonotal convexity raised as a right angle that drops off through a long, steep face to the metanotum; in dorsal-oblique view the pronotum, mesonotum, and propodeum each bear conspicuous paired angles or spines; the pronotal angles from above extend far beyond the rest of the pronotum below, and the propodeal spines are large and equilaterally triangular; head quadrate in full-face view, with posterior half smooth and anterior half partly carinulate; posterior half of dorsal head profile weakly concave; all of mesosoma and dorsal surface of head foveolate.

Minor: mesosoma configured as described for major; occiput very broad and flat.

MEASUREMENTS (mm) Holotype major: HW 0.70, HL 0.72, SL 0.34, EL 0.12, PW 0.40. Paratype minor: HW 0.40, HL 0.40, SL 0.32, EL 0.06, PW 0.24.

COLOR Major: head and mandibles light brown; mesosoma and other appendages medium brown; gaster dark, almost blackish brown.

Minor: the Panamanian types are dark brown; specimens from Costa Rica vary from reddish yellow to reddish brown.
