The following key to Teratomyrmex species has been modified from Shattuck & O'Reilly (2013[1]).

1

  • Colour uniform through entire body; pronotum with large, wing-like structures on dorsal surface; dorsal surface of petiole concave with a pair of small spines dorsolaterally => Teratomyrmex greavesi
  • Body darker on head and mesosoma with coxae, trochanters and basal one third of femora white (remainder of femora brown); pronotum lacking large wing-like structures, instead with angular pronotal humeri; dorsal surface of petiole flat, with very small projections dorsolaterally => 2

2

  • Body with long, erect hairs only, shorter hairs and pubescence absent; dorsum of head, pronotum and mesonotum essentially smooth, sculpturing at most only weakly developed; petiole uniform brown, apex similar in colour to remainder => Teratomyrmex substrictus
  • Body with both long, erect hairs and short, flat-lying hairs (short hairs absent from first segment of gaster); dorsum of head, pronotum and mesonotum with abundant shallow foveae; apex of petiolar node pale yellowish-white, distinctly paler than remainder of petiole => Teratomyrmex tinae
