Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.


Nests are made in the ground. Nest chambers have been found under rocks in higher elevation evergreen forest. Foragers have been collected from the ground, in leaf litter and on vegetation. This species has been found from 115 m, in dry forest, up to more than 1,100 m in pine forest.

Minor: propodeal spines very thick, curved, and sickle-shaped, much longer than the propodeal basal face anterior to them; body concolorous medium brown.

MEASUREMENTS (mm) Holotype major: HW 1.04, HL 1.02, SL 0.70, EL 0.14, PW 0.50. Paratype minor: HW 0.48, HL 0.52, SL 0.64, EL 0.08, PW 0.32.
