I could not activate the link cited above in the ''User's Notes'' Looking at the ALA A. atratella shows a northern NSW and SE Qld distribution, wheras A. gypsocrana has a SE NSW distribution. Both species seem to show two small white parallel marks on or just behind the thorax. To my eye looking online A. atratella seems darker in appearance witout the same dark dot pattern A. gypsocrana shows on the forewing. On this basis I tend to favour A. gypsocrana in this instance. I did not find the evidence on BOLD (Hobern) for A. atratella convincing, I'm happy to be convinced otherwise!
