The unmarked form of M. facetella is externally indistinguishable from other unmarked species of the genus, although it is one of the larger ones. Within its distribution range in Montenegro, the following species are known to occur: Micropterix aruncella (Scopoli, 1763) and Micropterix igaloensis Amsel, 1951. From both, M. facetella is completely different in the male genitalia, especially in the form of the accessory claspers. In the female genitalia, M. facetella is characterized by a distinct reticulation of sternites 7 and 8, which is absent in the other two species.
