A australis and A, orbona, at least, seem to have four large light coloured panels like this specimen photograhed, but A. plagiata apparently does not. A. plagiata also shows black barring in the pair of anterior white spots which is missing here.This specimen also seems the lack the black spotting on the head and thorax wihich online photos of A. australis and A. orbona show. The specimen appears very worn, so I'm not sure irs either of these two species. Looking online, (including on Bold Systems), I have found no convincing matches of this moth to named and photographed species. I would favour classifying this sighting as 'Asota (genus)'.
