There are opposing white costal and dorsal spots that may join into a fascia. The moth can be identified by breeding out from a mine or by genitalia dissection. Information on the genitalia is available in a publication by Erik J. van Nieukerken, Tijdschrift voor entomologie 128 1985 1–164 available from Biodiversity Heritage
