Probably not E. dioctis due to the lack of yellow forewing markings. Unlike LBH, I note that the Australian Faunal Directory recognises Eretmocera dioctis and E. chrysias as separate species. The moth's forewing markings and sighting location (ie tropical northern Australa) are consistent with Eretmocera chrysias https://bold-au.hobern.net/specimens.php?taxid=414581 https://v4.boldsystems.org/index.php/Taxbrowser_Taxonpage?searchMenu=taxonomy&query=Eretmocera+chrysias&taxon=Eretmocera+chrysias
