Major: also with broken transverse carinulae on pronotal dorsum; a small but distinct mesonotal convexity; propodeal spines reduced to denticles; and a large propodeal spiracle.

Minor: all of head and mesosoma foveolate and opaque; propodeal spines reduced to denticles. Similar to Pheidole browni, Pheidole casta, Pheidole mera, Pheidole olsoni and Pheidole prolixa, but easily distinguished by the above traits.
