Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.


A small, yellow member of the fallax group (but close to the diligens group) distinguished by the exceptionally thin propodeal spines of the major and minor, as well as the very low mesonotal convexity in side view in both castes; and, in the major, the exceptionally large spiracle.

Similar to Pheidole prostrata of Costa Rica, but easily distinguished in the major by the large spiracle, low mesonotal convexity, and presence of a rugoreticulum mesad to the eyes, as well as yellow coloration.

COLOR Major: body light reddish yellow, appendages yellow.
