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 antennal scapes and petiolar pedicels; also in the major by a proportionately small head; and in the minor by a strongly developed nuchal collar. P. cuevasi is distinguished as follows.

Major: rugoreticulum covering all the dorsal surface of the head except the occipital lobes, frontal lobes, and middle of clypeus; antennal scapes just reach the occipital corners; pronotal dorsum partly covered by transverse carinulae; first gastral tergite entirely smooth and shiny.

Minor: occipital neck extremely drawn out, and nuchal collar prominent; propodeal spines reduced to denticles.
