The following key to Peronomyrmex species is based on Shattuck (2006[1]) and Shattuck & Hinkley (2002[2]).

1

  • Sculpturing on dorsum of head essentially absent, limited to small, scattered punctures or superficial reticulations => 2

2

  • Antennal scrobes relatively well developed, with distinct rugae along inner margins; posterior face of postpetiole essentially flat; area between humeral angles convex => Peronomyrmex overbecki
