  • Smaller (HL <1.47); body covered with appressed silvery pubescence; eyes more or less entire => Polyrhachis bugnioni
  • Larger (HL >1.57); dorsal surfaces of body virtually without appressed pubescence; eyes posteriorly truncate => 2

2

  • Dorsum of mesosoma highly polished; lateral angles of petiole broadly and obtusely dentate => Polyrhachis boltoni
  • Dorsum of mesosoma closely sculptured, semi opaque; lateral angles of petiole acutely spinose => Polyrhachis scissa
