Identification
Kohout (2008) - I have examined and directly compared the holotype of Polyrhachis zopyra (OXUM) with the syntypes of P. zopyra edentula and consider they represent separate species. They differ in several characters, including the outline of clypeus that, in lateral view, is weakly, but evenly convex with a flat basal margin in P. edentula, while it is straight and rounds into a weakly impressed basal margin in P. zopyra. The pronotal and petiolar teeth are distinctly more acute in zopyra, while in P. edentula they are shorter with the dorsal petiolar teeth obtuse and situated very close together. The pubescence in P. zopyra is very closely appressed, smooth and rather tidy, with only a few erect hairs arising from the gaster and the dorsum of head. The pubescence in P. edentula is more abundant and somewhat longer, with numerous erect hairs arising from all body surfaces, including the mesosoma and petiole.
