Key to Teratomyrmex species based on workers

1. Colour uniform through entire body ( Fig. 6 B); pronotum with large, wing-like structures on dorsal surface ( Fig. 6 C); dorsal surface of petiole concave with a pair of small spines dorsolaterally....................................... greavesi

-. Body darker on head and mesosoma with coxae, trochanters and basal one third of femora white (remainder of femora brown) ( Fig. 7 B); pronotum lacking large wing-like structures, instead with angular pronotal humeri ( Fig. 7 C); 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 ( Fig. 7 )................................................................................................ 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 ( Fig. 8 )........................................................................ tinae
