female specimens of "p. fulvescens" can be confused with "p. virginica" and "p. lata". females of "p. virginica" are on average smaller and less robust, less often have wide coloration differences, normally have a supra-anal plate with straight lateral edges that converge in a more acute apex, have a less convex caudal (rear) edge of the sixth dorsal abdominal segment, and have fewer proximal spines of the cephalic femora. females of "p. lata" are much larger and more robust, with a more transverse pronotum.
