Scheme of wing pattern:

Description of adults: Examined: 3 , 1 . Forewing length: 3.9 mm; 4.4 mm. Head blackish, vestiture of hair-like scales on the head yellow; antennae approximately 3/4 () or almost 1/2 () of forewing length, golden fuscous; thorax coppery to bronzy golden, tegulae purple violet with bronzy golden edges; forewings purple violet to bluish violet; base of costa bronzy golden; wing markings golden, delicately bronzy golden bordered; a fascia at 1/4, slightly bent, moderately broad on inner margin, distinctly narrowed from centre of wing to costa; a fascia at 1/2, slightly bent outwards, moderately broad, sometimes narrowed medially, sometimes distinctly broadened at costa; a fascia at 3/4, slightly broader than the other ones with distinctly curved inner margin; sometimes a residual costal spot at 3/5; cilia bronzy golden, apically whitish; hindwing coppery to bronzy golden, apically distinctly tinged purple; cilia bronzy golden; legs and abdomen golden fuscous.

Distribution:

M. huemeri seems to be an endemic of the geologically isolated region of the Marguareis, France (Kurz et al. 2004). It has been found at a height of 2100 - 2200 m a.s.l. (Kurz & Kurz 2010).

Biology:

The species was found in high alpine grassland (at elevations higher than 2000 m) in tall herbaceous vegetation around boulders in July (Kurz et al. 2004, Kurz & Kurz 2010).

Stages in development:

The early stages are unkown.

Genitalia. Uncus short, slightly stout with moderately broad tip; ventrally beyond uncus a tuft of hair-like setae; a small area with several faint, straight setae at the posterior margin of tegumen between uncus and accessory claspers; accessory claspers proximally broad, distally tapered, on inner surface with an upper row of six sickleshaped thickened setae and a lower row of nine more or less straight, moderately long spinoid setae, with the two proximal spinoid setae being slightly apart; valvae slightly bent, constricted beyond middle with a triangular distal end and two or three irregular rows of shorter spinoid setae on inner surface beyond the constricted part of the valve; post-basally a distinctly robust seta on inner surface.

Genitalia. No attempt has been made to prepare the genitalia of the single available female of this species.

Externally, M. huemeri is quite well separated from other species by its three complete golden fasciae on the forewing and the absence of any further markings. One exception is Micropterix trifasciella Heath, 1965, which has very similar wing pattern elements with only slightly broader fasciae on the forewing. However, the male genitalia of M. huemeri differ in the shape of the accessory clasper which is conspicuously narrower proximally and has a different arrangement of the thickened setae. Furthermore, on the inner surface of the valve, the row of the short and thickened setae extends further towards the base into the constricted part of the valve.
In M. huemeri, the structures of the male genitalia are most similar to those of Micropterix rothenbachii Frey, 1856. M. huemeri can be distinguished superficially from M. rothenbachii by both the lack of a small costal golden spot and the golden tinge on the outer margin of the forewing. Concerning the male genitalia, M. rothenbachii has a distally club-shaped uncus and longer, distally more spatulate valvae with only one stout spinoid seta in the middle of the constriction.

Phylogeny: M. huemeri belongs to a group of morphologically closely allied species which show the following common characters: The accessory claspers, seen laterally, bear two rows of thickened setae. In the ventral row, the distal thickened setae are strongly modified (Y- or T-shaped), and the one or two proximal most ones are distinctly separated from the rest of the row. These characters are shared by M. huemeri, M. rothenbachii, Micropterix allionella (Fabricius, 1794) and M. trifasciella.
