Longitudinal rugae on cephalic dorsum prominent, weakly wavy to irregular, sometimes weakly rugoreticulate on medioposterior margin; in full-face view, medial rugae diverging weakly toward posterior corners of head. In profile, rugae posterior to eyes converging toward vertex. Cephalic interrugae weakly granulate, shining; vertex rugose. Anterior margin of clypeus flat to weakly concave; dorsal surface with numerous subparallel, longitudinal rugae. Mandible with six teeth; mandibular dorsum coarsely rugose. Numerous long, curved, bristle-like, yellowish hairs project from anterior margin of clypeus and basolateral margin of mandibles. MOD ranging from 0.18–0.23x HL. In profile, eyes situated near middle of head, OMD = 1.19–1.60x MOD. Antennal scapes relatively long (SI = 60.34–81.52), failing to reach vertex by up to length of basal funicular segment; scapes smooth and shining, distal portion often weakly striate. Basal flange of scape flattened, well-developed with carinate margin. Psammophore well-developed.

. In describing the species, Santschi (1922) listed the type locality as Masao, Catamarca Province, Argentina (see also Baldini & Scattolin, 1993). Alternatively, Gallardo (1932) listed the type locality as Masas, and Kempf (1972) apparently questioned the locality by indicating it as <Masao> (=Mazán?). Additionally, the label on an MCZ specimen was interpreted as Valle Masan.

. (2012) used to suggest that both queen phenotypes initiate nests using independent colony founding. Little is known about mating, but ergatoid queens have been collected from 6 February to 16 April. Brachypterous queens were larvae, pupae, or callows near the end of January and mature brachypterous queens have been collected from 20 February to 9 April. Mating has not been observed, but both ergatoid and brachypterous foundresses have been observed running on the ground (Mar 23 for ergatoid queens; Mar 24–25 for brachypterous queen), and both phenotypes exhibit independent colony founding; one haplometrotic ergatoid queen was excavated on March 22, and one haplometrotic brachypterous queen was excavated on March 24. Both ergatoid and brachypterous foundresses were observed to forage outside the nest (pers. obs.). Mating activities and colony founding appeared to have been triggered by late summer rains.
