The following key to Austromorium species is based on Shattuck (2009).

• Body smaller (head width < 0.85mm), gaster banded (honey yellow anteriorly and posteriorly, brown medially), propodeal lobes developed as sharp spines posteriorly (widespread across southern Australia) => Austromorium flavigaster

• Body larger (head width > 1.30mm), gaster uniformly coloured dark brown, propodeal lobes large and rounded posteriorly (restricted to coastal plain between approximately Geraldton and Perth, Western Australia) => Austromorium hetericki
