The following key to Australian Odontomachus is based on Brown (1976[1], 1978[2]).

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
