. Head subquadrate to quadrate (CI = 92.37–105.69), widest just posterior to eye; posterior margin flat to weakly concave. Longitudinal rugae on cephalic dorsum prominent, occasionally weakly rugoreticulate especially near posterior margin; approximately 8–10 coarse, longitudinal rugae between frontal lobes; in full-face view, medial rugae not diverging toward posterior corners of head. In profile, area posterior to eyes rugose to moderately rugoreticulate, rugae not converging toward vertex. Cephalic interrugae moderately to strongly granulate, dull to weakly shining; vertex rugose. Anterior margin of clypeus moderately to strongly concave, dorsal surface with numerous subparallel, longitudinal rugae; lacking small lobe that projects dorsally from anterior margin of antennal fossa. Mandible with six teeth; mandibular dorsum coarsely rugose. Up to several moderately long, curved, bristle-like, yellow-brown to brownish hairs project from anterior margin of clypeus and basolateral margin of mandibles. MOD ranging from 0.20–0.25x HL. In profile, eyes situated anterior to middle of head, OMD = 0.80–1.19x MOD. Antennal scapes moderately long (SI = 66.67–85.09), failing to reach vertex by 1.0–1.5x length of basal funicular segment; entire scape with strong longitudinal striae, dull to weakly shining; basal flange of scape flattened and well-developed with carinate margin. Psammophore poorly-developed, consisting of short to medium-length hairs scattered across ventral side of head.

Alta Gracia and La Granja are two small towns that are located approximately 75 km apart along the eastern side of the Sierras de Córdoba. Thus, the labels suggest that the type locality was somewhere between these two towns.
