Dusky Brindled Pearl (Udea prunalis)

Observation - Dusky Brindled Pearl (Udea prunalis). Description: A moth I've been puzzling over for a while. Came to a light left on overnight. The size and shape of a carpet moth but I can't find anything like it in Waring and Townsend. Can anyone help, please? Edit: 2nd photo added. Taken with flash so colour may be
