I' m not sure this is A. demistis. The shape of the forewing outer margin is not recurved, the moth has a dark thorax and a light coloured head. Loweria (genus)?
Given there is no close match I can find in Loweria (genus), I instead suggest Amelora (genus). This is because the closest match I could find to this sighting is Sighting No 4474673 . See my note to that sighting.
