This species was described recently by Jennings et al. (2004a) from the Fitzgerald River National Park, Western Australia . In addition to the description provided in Jennings et al. (2004a) , the ovipositor guide is medial, transverse and broad, with short setae on the distal margin and in groove. Aulacus houstoni keys out with A. longiventris and A. belairensis . The three species can be separated readily by the lateral medial carina above the toruli, which is present in A. longiventris and A. houstoni but is absent in A. belairensis . For additional differences, see under A. belairensis above.
