Description of adults:
Examined: 15 , 13 (incl. holotype von M. rebeli Viette). Forewing length: 2.8 - 3.8 mm, 3.8 - 4.0 mm. Head black-brown; vestiture of hair-like scales on the head dirty white to yellowish; thorax bronzy golden, distally purple; tegulae purple violet; forewings coppery to purple with whitish golden to golden, distinctly, but delicately bordered bronzy golden; inner margin bronzy golden from basis to fascia at 1/4 in a faint streak; at 1/4 a nearly straight fascia across the whole wing width; a moderately broad, slightly outwardly oblique fascia across the whole wing width at 1/2; at slightly more than 3/4 an irregular spot, from near costa inwardly oblique towards the middle of the wing; fringe golden, whitish outwards; hindwings reddish bronzy golden; fringe bronzy golden, lighter outwards; legs and abdomen brown, golden shining.

Distribution:

The species seems to be widely distributed on the Iberian peninsula (Corley 2007, Karsholt & Nieukerken 2011, Kurz & Kurz 2011). In 2003, the species has been recorded for the first time from Morocco by R. Hausenblas and C. Zeller. Its vertical distribution has been documented so far only from 660 - 980 m a.s.l. (Kurz & Kurz 2011).

P. Huemer and C. Wieser (pers. comm.) found Micropterix ibericella on the flowers of Fraxinus ornus, feeding on pollen together with Micropterix granatensis Heath, 1981. The imagines are on the wing in April and early May (Kurz & Kurz 2011).

Stages in development:

The early stages are unknown.

Genitalia. Uncus more or less short, with broadly rounded tip; beneath the uncus, inside the tegumen, a small structure with hair-like setae; on the distal margin of the tegumen, slightly above the onset of the accessory claspers, a small area of setae; the accessory claspers broad, only slightly separated from the distal margin of the tegumen; on their distal margin, on the inner surface, a row of about 18 short, stout and thickened setae, the three distalmost of them strongly modified, sickle-shaped, the two proximalmost somewhat inflated, the others straight to slightly sickle-shaped; above this row a second row of about 10 very short, slightly bent, distally directed, stout and thickened setae, the distalmost of them modified; valves moderately long and slender, distinctly constricted distad of the middle, elongated spatulate at the distal end; at the inner surface postbasally with two stout setae, the distal third with 1 - 2 rows of very short, straight, stout and thickened setae.

Genitalia. Tergite IX missing; sternite IX reduced, narrowed medially, with indistinct lateral margins; papillae anales consisting of two narrow, band-like sclerotized platelets; receptaculum seminis moderately long, narrow in distal half, bag-like inflated in proximal half, with distinct, but weak striation.

At the northern border of its distribution range, the species may be confused only with Micropterix aglaella (Duponchel, 1840). The latter has distinctly broader fasciae, the inner margin at the base being bronzy golden in a much broader stripe. Micropterix stuebneri Zeller, Werno & Kurz, 2013 from the Sierra Nevada shows an extended bronzy golden colouration along the inner as well as along the outer margin, which is missing in M. ibericella. In the male genitalia, M. ibericella is well separated from others. The only African specimen so far investigated, is considered to be conspecific, although its uncus seems to be slightly shorter and more stout. In the female genitalia, M. stuebneri from the Sierra Nevada has the papillae anales medially with much broader platelets, whereas sternite IX is distinctly smaller. In the females of M. aglaella, the platelets of the papillae anales are also broader than in , sternite IX is less well sclerotized.

Phylogeny:With respect to the male genitalia, we do not know of any close allies. Some characters however, especially the shape of the accessory claspers, indicate some resemblance to a species group around Micropterix rothenbachii (Frey, 1856).
