Keys including this Species
Distribution
Colombia, and one series from near Flor de Oro, Santa Cruz, Bolivia, 450 m (P. S. Ward). Kempf (1972b) reports the species from Catamarca, Argentina, a surprising record that needs to be confirmed. (Wilson 2003)
Distribution based on Regional Taxon Lists
Neotropical Region: Argentina, Bolivia, Colombia (type locality).

Description
From Wilson (2003): A medium-sized, yellowish brown member of the diligens group with long, erect pilosity, close to Pheidole coffeicola and Pheidole variegata (= Pheidole pubiventris), differing, as figured, in the major class by its shorter scapes, denser pilosity, triangular and pointed mesonotal convexity in side view, and more extensive cephalic rugoreticulum, which rugoreticulum stretches from the eyes to the circular carinulae surrounding the antennal fossae. See also the less similar Pheidole laevifrons, Pheidole laevinota, Pheidole pubiventris and Pheidole rufipilis.
MEASUREMENTS (mm) Lectotype major: HW 1.28, HL 1.28, SL 0.88, EL 0.20, PW 0.64. Paralectotype minor: HW 0.64, HL 0.74, SL 0.96, EL 0.18, PW 0.44.
COLOR Major: body and appendages yellowish brown, with the gaster a darker shade.
Minor: concolorous yellowish brown.
Figure. Upper: lectotype, major, including views from rear of both mesonotal convexity and petiolar node. Lower: paralectotype, minor. Scale bars = 1 mm.
Type Material
COLOMBIA: no further locality. Musee d'Histoire Naturelle Genève - as reported in Wilson (2003)
Etymology
