Key to Australian Odontomachus Species

The following key to Australian Odontomachus is based on Brown (1976, 1978).

1

• Dorsum of first gastral tergite smooth, finely punctate or leather-like, or at most partly striate on the posterior half => 2

• Dorsum of first gastral tergite completely striate => 3

2

• First gastral tergite in part densely and finely sculptured, at least in a strip along the posterior border; pronotum in profile angled medially => Odontomachus ruficeps

• First gastral tergite uniformly smooth and shining, though sometimes with minute, discrete punctures and pubescence distributed over most or all of its dorsal surface; pronotum in profile uniformly convex => Odontomachus simillimus

3

• Erect hairs absent from pronotum and first gastral tergite => Odontomachus cephalotes

• Erect hairs present on pronotum and first gastral tergite => Odontomachus turneri
