Description
A unique medium-sized, yellowish brown species whose major has a heart-shaped head, when mandibles are included, in full-face view; all of the dorsal head surface, including the clypeus but excluding the occiput, densely covered by longitudinal carinulae; conspicuously swollen hind femur; and angulate subpostpetiolar process.
There is some similarity to Pheidole erratilis, Pheidole nitella and Pheidole pygmaea, but many differences in body form, sculpturing, and color.
