Longitudinal rugae on cephalic dorsum weak, wavy to irregular; in full-face view, medial rugae diverging weakly towards posterior corners of head. In profile, rugae posterior to eyes converging near vertex, occasionally weak to indistinct near vertex. Cephalic interrugae strongly granulate, dull; vertex moderately granulate or rugose, interrugae weakly to moderately granulate, weakly shining to shining. In frontal view and from posterior margins of head looking down over cephalic dorsum, frontal lobes poorly-developed, lateral margins subparallel, projecting nearly parallel to cephalic dorsum. Anterior margin of clypeus concave; dorsal surface with several subparallel longitudinal rugae. Mandible with six teeth; mandibular dorsum coarsely rugose. MOD ranging from 0.21–0.28x HL. In profile, eyes situated slightly anterior to middle of head, OMD = 0.88–1.25x MOD. Antennal scapes moderately long (SI = 64.56–77.42), failing to reach vertex by length of basal funicular segment; entire scape with longitudinal striae. Psammophore well-developed.

. With caste-specific morphology of the mesosoma related to wing-bearing and presence of ocelli on head. In full-face view, head quadrate to slightly wider than long (CI = 100.00–105.29), widest just posterior to eyes, posterior margin flat. Longitudinal rugae on cephalic dorsum prominent, wavy to irregular; in full-face view, medial rugae not diverging toward posterior corners of head, interrugae weakly granulate-punctate, weakly shining to shining; vertex rugose, interrugae weakly granulate-punctate, weakly shining to shining. Mandible with six teeth, dorsal surface coarsely rugose. Psammophore well-developed.

All mesosomal surfaces with subparallel, regular, wavy, or irregular rugae; interrugae on mesoscutum and mesoscutellum weakly coriarious, weakly shining to shining, those on propodeum moderately to strongly granulate-punctate, dull; propodeum with short superior spines; inferior propodeal spines absent. Peduncle of petiole long, anteroventral margin with weakly to moderately well-developed triangular process. In profile, petiolar node asymmetrical with anterior surface notably shorter than posterior surface, apex rounded to weakly angulate. Posterior surface of petiolar node and dorsum of postpetiole with irregular transverse rugae; rugae on postpetiole weaker, often faint to absent medially; interrugae on posterior surface of petiolar node and dorsum of postpetiole weakly granulate-punctate, weakly shining. First gastral tergum weakly coriarious, shining to strongly shining. Most body surfaces with moderately abundant suberect to erect, medium-length, white to yellowish setae; moderately abundant suberect to erect hairs on first gastral tergum, those on second and third terga restricted to posterior margin. Body mostly concolorous tannish-brown (

Collection dates for sexuals range from 30 November to 21 December. Mating flights have not been observed, but they occur during the austral summer (December–January) based on finding dealate queens on the ground on 19 & 26 December. Several dealate queens also were collected foraging outside the nest. Several ant species have queens that sometimes apparently forego mating and later perform tasks such as foraging and nest maintenance (Peeters, 1997). Reproductive status was not determined for these queens, but they are assumed to have been unmated given that foraging queens (both ergatoid and dealate) are unmated in
