This species was described new to science in 2002 and belongs to the Elachista cingillella complex. After investigation by L. Kaila & J. Junnilainen, this complex consists of 6 valid species. All references to Elachista cingillella from southern Europe and Belgium in fact concern Elachista metella.
Recorded from the province of NA as Elachista cingillella based on three male specimens which were caught at Belvaux on 26.v.1980, leg. & gen. det. G. & W. De Prins. During 2019 two specimens were collected near Resteigne (LX) and Modave (LG).
Hitherto a very rare and local species.
