Genitalia. Uncus moderately long; below uncus, at posterior margin of tegumen, a broad lobe on each side with numerous very long, backwardly directed, straight, stout and thickened setae; accessory claspers broad triangle-shaped, at lower margin at inner surface with a medially interrupted row of very long to long, straight, stout and thickened setae, wich are downwardly directed; inside tegumen two long and slender appendages with spoon-like apex, bearing inwardly directed, long and curved, stout setae; valvae long and slender, distal 2/5 bent upwards; at inner surface of distal fourth 2-3 irregular rows of short, straight, spinoid setae, as well as several long thin setae.

Genitalia. Tergite IX missing; sternite IX reduced, but with distinct margins; segment X with band-like, medially enlarged sclerotization; receptaculum seminis short, proximal half bag-like inflated, distinctly striated.

Diagnosis:

From Micropterix schaefferi Heath , 1975, the species is best distinguished externally by the reduced golden inner margin. The same applies to Micropterix sp. (Samos), which also lacks the small costal spot at 3/5.
In the male genitalia, the species differs from both by the broad lobe between uncus and accessory claspers, bearing long, stout and thickened setae, as well as by the form of the accessory claspers, bearing different setae. The female genitalia are not characteristic and not separable from M. schaefferi and M. species (Samos).

Phylogeny: The slender appendages inside the tegumen, bearing inwardly directed, curved setae seem to be homologous to those in Micropterix corcyrella Walsingham, 1919. They are known so far only from those two species. Similar and unique to both species are also the very long, straight, stout and thickened setae on the accessory claspers, being divided into two areas.
