I'm not sure I can match this easily with any oof the Prays (genus) species here:- https://v4.boldsystems.org/index.php/Taxbrowser_Taxonpage?searchMenu=taxonomy&query=Prays+&taxon=Prays+
I think it is a very worn Monopis sp. I think that I saw the same moth again the following day and managed to photograph it from the side. See sighting 4664992.
