From Wilson (2003): A member of the “jujuyensis complex” of the larger fallax group, comprising Pheidole araneoides, Pheidole cuevasi, Pheidole durionei, Pheidole jujuyensis, Pheidole kugleri, Pheidole leonina, Pheidole leptina, Pheidole lucretii, Pheidole lupus, Pheidole paraensis, Pheidole punctithorax, Pheidole tijucana, Pheidole wallacei and Pheidole wolfringi, which complex is characterized in both major and minor by slender body form and exceptionally long scapes and petiolar pedicel; also in the major by a proportionally small head; and in the minor by a strongly developed nuchal collar. P. jujuyensis is distinguished as follows.

Major: scape fails to reach occipital corner by more than its own maximum width; pronotal dorsum smooth and shiny; mesopleuron and sides of propodeum transversely carinulate; first gastral tergite mostly shagreened and opaque.

Minor: occiput thinned into a neck; mesopleuron carinulate.

Both major and minor are extremely pilose, with abundant, exceptionally long, erect hairs on all appendages.

MEASUREMENTS (mm) Major: HW 1.66, HL 1.80, SL 1.50, EL 0.26, PW 0.84. Lectotype minor: HW 0.64, HL 0.90, SL 1.52, EL 0.20, PW 0.50.

COLOR Major: body mostly medium brown with slight reddish tinge; mandibles, pronotal dorsum, mesothorax, propodeum, and waist dark plain brown.

Minor: head and mesosoma dark reddish brown; appendages, waist, and gaster light reddish brown.
