Aulacus belairensis Jennings, Austin & Stevens, 2004

Aulacus belairensis Jennings et al. 2004b: 14 ; Jennings 2010 [on-line checklist].

Comments. This species was described recently by Jennings et al. (2004b) from Belair, South Australia. In addition to the description provided in Jennings et al. (2004b), the ovipositor guide is distal, transverse, distal fringe with long setae, and no setae in the groove.

Aulacus belairensis keys out with A. longiventris and A. houstoni . The three species can be readily separated by the lateral medial carina above the toruli, which is present in A. longiventris and A. houstoni but absent in A. belairensis . They can also be separated by the position of the ovipositor guide on the hind coxae (transverse and distal in A. belairensis , transverse, medial and broad in A. houstoni , and transverse and somewhat caudad in A. longiventris ). There are also colouration differences (see key above).
