This species does not fit Wilson's key to Pheidole and is either a new species or variation of another species, such as P. tetra. It is a fairly large soil dwelling species that has been found in open areas in forests. Species in this species group have scapes flattened at the basally in the majors. This species can be distinguished from others in the group in this region by the numerous erect hairs on the gaster, petiole and postpetiole, alitrunk, and head (especially occipitally) of the major. This species is quite similar to P. tetra, but lack erect hairs on the occiput.
