Pheidole punctithorax Borgmeier   HNS 1929: 210.

Types Mus. Zool. Univ. Sao Paulo.

Etymology l punctithorax   HNS , punctate chest, evidently referring to the wholly foveolate mesosomas of both castes.

diagnosis A member of the " jujuyensis   HNS complex" of the larger fallax   HNS group, comprising araneoides   HNS , cuevasi   HNS , durionei   HNS , jujuyensis   HNS , kugleri   HNS , leonina   HNS , leptina   HNS , lucretii   HNS , lupus   HNS , paraensis   HNS , punctithorax   HNS , tijucana   HNS , wallacei   HNS , and wolfringi   HNS , which complex is characterized by slender body form and exceptionally long scapes and petiolar pedicel; also in the major by a proportionately small head; and in the minor by a strongly developed nuchal collar. P. punctithorax   HNS is distinguished as follows.

Major: pilosity sparse; occiput narrowed so that its width in full face is much less than that of the clypeus; a loose, large-celled rugoreticulum is limited to the space mesad to the eyes and forward of it; the humerus and petiolar node are subangulate; all of the occiput, mesosoma, and waist are foveolate and opaque; anterior third of first gastral tergite is shagreened and opaque. Minor: all of mesosoma and waist, as well as a strip running from the eye to the occiput, foveolate and opaque; neck only moderately narrowed. Major and minor: reddish brown.

Measurements (mm) Holotype major: HW 1.24, HL 1.32, SL (antennae missing), EL 0.22, PW 0.64.
