The native Pheidole species most commonly seen in the south-west corner of WA (Heterick 2009).


Heterick (2009) - The minor workers of this and related forms are difficult to determine with accuracy, many having a relatively uniform morphology. The major workers, however, appear to have more taxonomically useful characters. One of these is the morphology of small teeth or denticles to be found on the anteroventral margin of the head capsule (Ogata and Yamane 2003). The major of P. ampla perthensis has horizontal ridges near the margin of the vertex.

Minor workers are very variable in sculpture, those from inland regions having a much smoother, shinier promesonotum compared with ants from mesic coastal or southern, forested areas. In the latter, the promesonotum is duller with varying degrees of microreticulation, along with small striae. Intermediate forms connect the two extremes.
