The size, shape, prominent large eyes and silvery iridescent forewings are very distinctive in this moth. Don, I dont think it matches any of your suggestions so far. I will keep looking.
Looks similar wrt to the the LBH photo, but thats not much to go on given there a re so few images online. However, there is a hint of the outer straight line section of the costa visible here which is reflected in the LBH specimen. eyes are large in the set speciment too.
I alerted Axel Kallies to these sightings as he et al are researching Heliozelidae at present e.g. https://arthropod-systematics.arphahub.com/article/130334/ his comment on this sighting is "The one identified as Hoplophanes aerodes is also a Gelechiidae"
