Cephalic dorsum, sides, and vertex rugose, rugae variable in height; in full-face view, medial rugae not diverging toward posterior corners of head. Cephalic rugae deeply incised, interrugae strongly granulate, dull. Anterior margin of clypeus convex with medial triangular tooth, dorsum of clypeus with numerous subparallel, wavy, longitudinal rugae similar to those on cephalic dorsum. Mandible with six teeth; mandibular dorsum coarsely rugose. Up to several moderately long, curved, bristle-like, amber to brownish hairs project from anterior margin of clypeus and basolateral margin of mandibles. Eyes small, MOD = 0.130.17x HL. In profile, eyes situated anterior to middle of head, OMD = 1.52 2.00x MOD; no hairs project from between ommatidia. Antennal scapes long (SI = 77.72104.82), reaching to surpassing vertex by less than length of basal funicular segment; entire scape with weak longitudinal striae, interstriae strongly granulate, dull. Basal flange of scape well-developed with recurved, carinate margin. Psammophore poorly-developed, consisting of numerous short hairs scattered across ventral side of head.

Nests have one large (13 cm diameter), irregularly-shaped entrance, and the nest is normally covered by dry leaves, a log, or a stone; the nest lacks a crater, mound, or tumulus. Nests contain two to three chambers and range from 1522 cm deep. Nest density ranges from approximately 50150/ha; density decreases at elevations&gt;100 m (Kugler &amp; Hincapie, 1983).</paragraph>

are diurnal scavengers that forage on the surface of the leaf litter or bare soil. Diet varies seasonally; more insects (especially termites and isopods) are harvested during the wet season (probably because of increased availability), while flower and leaf fragments are more commonly harvested during the dry season. Dead and dry arthropods comprise&gt;50% of the harvested items in both seasons, but larger insects that struggle are avoided; seeds account for a small portion of the diet (ca. 10%) regardless of season. Colonies are small and consist of from 200900 workers plus 25270 larvae and pupae, and up to 28 males. Thus, overall colony size ranges from 2841020 individuals (Kugler, 1984; Kugler &amp; Hincapie, 1983).

Nothing is known about production of ergatoid queens (Kugler &amp; Hincapie, 1983). Interestingly, ocelli were not visible on either of two examined ergatoid queens indicating that the ocelli are vestigial or absent, and Kugler (1979) did not mention ocelli in his description of the ergatoid queen.
