Key to Peronomyrmex Species

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

1

 * Sculpturing on dorsum of head consisting of distinct longitudinal rugae => Peronomyrmex bartoni


 * 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


 * Antennal scrobes little more than shallow troughs, lacking rugae along their margins; posterior face of postpetiole broadly concave; area between humeral angles flat => Peronomyrmex greavesi
