Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.


From Wilson (2003): A large, relatively thin and long-legged member of the “jujuyensis complex” of the larger fallax group, comprising Pheidole araneoides, Pheidole chocoensis, Pheidole cuevasi, Pheidole jujuyensis, Pheidole kugleri, Pheidole leonina, Pheidole leptina, Pheidole lucretii, Pheidole lupus, Pheidole paraensis, Pheidole punctithorax, Pheidole tijucana, Pheidole wallacei and Pheidole wolfringi. P. wallacei is distinguished by the following combination of traits.

Major: scape surpasses antennal corner by about its own greatest width; carinulae reach midpoint of head capsule, and very small rugoreticular patches present laterad to circular carinulae of antennal fossae; humerus subangulate in dorsal-oblique view; propodeal spine small, equilateral in shape in side view.

Minor: occiput drawn out into a neck with a nuchal collar; body almost completely smooth and shiny; propodeal spine well-developed and relatively thin.

MEASUREMENTS (mm) Lectotype major: HW 1.74, HL 1.88, SL 1.60, EL 0.26, PW 0.96. Paralectotype minor: HW 0.74, HL 1.26, SL 2.04, EL 0.24, PW 0.58.

COLOR Major: concolorous reddish yellow.

Minor: concolorous medium yellow.
