This looks like Endeolena (genus) at least, but I;m not sure of the species. The two named species: E xanthiella and E, aurinatella seem to be quite variable as seen online elswhere, Seems more likely to be E. xanthiiella, but I;m not sure. Not all examples of the species show such a distincytdarker trailing edge to the forewing as in this example or as an extensive darker forewing mark.
