Aulacus houstoni Jennings, Austin & Stevens, 2004

Aulacus houstoni Jennings et al. 2004a: 117 ; Jennings 2010 [on-line checklist].

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.
