Pheidole noda is a large, long-limbed, dark colored species most easily recognized by its distinctly enlarged dome-like postpetiole. The species belongs to a clade of large-bodied species that has diversified across Indomalaya (Economo et al. 2015). Although both P. noda and P. megacephala are considered to have an enlarged postpetiole, they are very different in shape. That of the former is dome-like (Fig. 2) and that of the latter has an anteroventral bulge in addition to the posterodorsal bulge (Fig. 1). The majors of P. noda are easily separated from those of P. megacephala by the strongly sculptured face (Fig. 8 vs. Fig. 9). The minors both have glossy faces, but those of P. noda are larger with relatively longer antennal scapes (Fig. 39 vs. Fig. 40). Pheidole noda is occasionally confused with other Asian tramp Pheidole, including P. fervens and P. indica, but both major and minor workers are easily separated from these by the enlarged postpetiole. Readers are referred to Eguchi (2008) for characters used to separate P. noda from its other Asian congeners.
