Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.
Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
A large brown member of the flavens group whose major is distinguished by its square head shape in frontal view, angulate profile of the mesonotal convexity, and rugoreticulate mesosomal dorsum.
The minor is very distinctive in the completely rugoreticulate condition of the posterior half of the head, promesonotal dorsum, and mesopleuron.
Similar to Pheidole quadriceps of Colombia but differs in the major by its much shorter propodeal spine, less extensive sculpturing on the head, the rugoreticulum of the mesosoma, which is completely lacking in quadriceps, and in color, and in the minor by the mesosomal rugoreticulation, which is absent in the quadriceps minor, and also in color. See also the less similar Pheidole kuna, Pheidole obtusopilosa, Pheidole rectisentis, Pheidole scabriventris and Pheidole termitobia.
MEASUREMENTS (mm) Holotype major: HW 1.14, HL 1.14, SL 0.62, EL 0.14, PW 0.54. Paratype minor : HW 0.54, HL 0.66, SL 60, EL 0.06, PW 0.38.
COLOR Major: head bicolorous, with head anterior to eyes yellow and remainder of head light brown (the holotype may be a callow); body light brown; tarsi and funiculi yellow; rest of legs light brown. Minor: body dark brown; tarsi and funiculi dark yellow; rest of appendages medium brown.
