@donhe I couldn't find many non-pinned photos of T psephonoma. The general top wing pattern seems right but this one was bright white rather than cream. It did remind me of an ermine moth colours. Do T psephonoma have stripey legs?
Thyridectis psephonoma looks most likely to me. I scanned Lacturidae at first but overllooked the entry on LBH! There is black and white on a leg here: https://lepidoptera.butterflyhouse.com.au/lact/psephonoma.html This photo of a set specimen does seem to show the mutiple striped leg.:-https://bold-au.hobern.net/specimen.php?processid=ANICF506-10
A new species for NatureMapr's Greater Brsbane region if confirmed. Excellent photos of a species for which photos from life are apparently rare online .
