Diagnosis A large reddish yellow (light "orange") member of the pilifera   HNS group.

Major: anterior half of head densely carinulate, with a few carinulae traveling along the dorsal midline all the way to the occiput, and the entire remainder of the body smooth and shiny; propodeal spines well-developed and vertical to the basal propodeal face; the petiolar node seen from the side tapering to a point; the postpetiole seen from above very broad, and spinose.

Minor: propodeal spines well-developed and vertical to basal propodeal face; almost all of the head and mesosoma smooth and shiny.

Measurements (mm) Lectotype major: HW 1.72, HL 2.14, SL 0.78, EL 0.22, PW 0.86.

Paralectotype minor: HW 0.54, HL 0.60, SL 0.56, EL 0.14, PW 0.38.

color Major: concolorous light reddish yellow (light "orange").

Range Southern Arizona into Mexico.

Biology Three colonies were found in a vacant lot in Tucson by Stefan Cover (unpublished field notes), nesting in clayey soil; two had cryptic entrances, and one had a rudimentary crescentic crater of excavated soil. Wheeler's type series were taken from nests in open sandy soil, the entrances of which were also marked by incomplete craters. The species harvests seeds.
