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)

Description
Medium-sized brown member of the flavens group, whose major and minor have exceptionally long, abundant, erect to suberect hairs over most of the body, foveolate and opaque mesosoma and petiole, and small, nearly oval postpetiolar node only slightly wider than the petiolar node.
Major: promesonotum with convexities in dorsal-oblique view; petiolar node in rear view strongly convex; carinulae on the midline dorsum of the head reach the occiput.
Minor: humerus angulate in dorsal-oblique view; dorsal surface of head mostly foveolate and opaque.
Similar to Pheidole amabilis, Pheidole melastomae, Pheidole mixteca, Pheidole scitula, Pheidole terresi and Pheidole tysoni differing in the combination of traits cited above.
MEASUREMENTS (mm) Holotype major: HW 0.86, HL 0.90, SL 0.46, EL 0.14, PW 0.44. Paratype minor: HW 0.50, HL 0.54, SL 0.44, EL 0.10, PW 0.34.
COLOR Major: head, mesosoma, waist, gaster, and antennae dark brown; legs brownish yellow.
Minor: dorsa of head and mesosoma medium brown; rest of body medium brown to brownish yellow; appendages brownish yellow.
