I wonder if the wing is curved under a little obscuring the dark line https://bold-au.hobern.net/specimens.php?taxid=326756 or mabe it is this https://bold-au.hobern.net/taxon.php?taxid=64972
The moth here has the same speckled appearance as E. epomadia, but doesn't seem to show the same darker marking pattern of that species or the strongly barred antennae that most other photos of the species show elswhere. A photo taken from side on, if available, would greatly assist in identification.
