Pheidole virago WheelerHNS

Pheidole virago WheelerHNS 1915b: 401.

types Mus. Comp. Zool. Harvard.

Etymology L viragoHNS, female warrior.

Diagnosis A very large, reddish brown (major) to reddish yellow (minor) member of the piliferaHNS group. Major: anterior third of head completely carinulate, with some carinulae that originate on the frontal lobes almost reaching the occiput; pronotum and mesonotal convexity completely covered by transverse carinulae; in dorsal-oblique view, promesonotal profile evenly trilobous; a small metanotal convexity present; the propodeal spines large and perpendicular to the basal propodeal face; postpetiole seen from above very broad and conulate.

Minor: dorsal surface of head and sides of mesosoma longitudinally carinulate; pronotal dorsum covered by a mix of longitudinal carinulae and rugulae; propodeal spines perpendicular to basal propodeal face; dorsal margin of petiolar node strongly convex; postpetiolar node depressed.

Measurements (mm) Lectotype major: HW 2.02, HL 2.20, SL 0.84, EL 0.20, PW 0.90. Paralectotype minor: HW 0.60, HL 0.66, SL 0.64, EL 0.12, PW 0.40. Color Major: concolorous light reddish brown. Minor: reddish yellow.

Range Texas to Arizona.

Biology Extremely rare. Wheeler's type series were from nests in open sandy soil, marked by 1-cm-wide entrances surrounded by craters of sandy soil 8 to 12 cm across. Ingham (1959, 1963; unpublished theses quoted by Alfred 1982), reported viragoHNS at 900 m in southern Utah, in desert and semidesert, variously with creosote bush, bur sage, rabbitbrush, cholla, marigold, and Russian thistle, forming crater nests in open soil. However, the Utah records are doubtful and need field confirmation.
