Scheme of wing pattern:

Description of adults: Examined: 12 , 4 [incl. type series]). Forewing length: 2.7 - 3.2 mm; 3.3 - 3.8 mm. Head brown; vestiture of hair-like scales on the head dirty to rusty yellow; antennae brown, dark golden shining, 3/4 (), respectively, more than 1/2 () of forewing length; thorax and tegulae bronzy golden, purplish distally, sometimes with single blueish scales; forewings bronzy to reddish golden, at apex slightly purplish tinged; base of costa purple too; markings silvery white: A small, straight fascia at nearly 1/4, especially in not always reaching costa; a similar, sometimes slightly irregular fascia at 1/2 across the whole wing width, sometimes interrupted in middle; at 3/4 a more or less pear-like spot, sometimes slightly touching costa, oblique towards center of wing; fringe greyish bronzy, purplish at base, whitish outwards; hindwings deep bronzy golden, more or less tinged purplish, especially towards apex; fringe bronzy golden; legs and abdomen brown, golden shining.

Distribution:

The species has been found so far in the Ligurian Alps (somewhat doubtful due to the lack of males), as well as in the northern Appenines (provinces of Liguria, Tuscany and Emilia Romagna). Most probably, the specimens from Tuscany and Emilia, identified by Heath (1981) as Micropterix italica Heath, 1981, also belong to M. renatae. A specimen from Passo delle Radici, published by Hartig (1973) under the name italica, undoubtedly is M. renatae, since the locality is only a few kilometers apart from the type locality. The vertical distribution is known to reach at least from 300-1050 m a.s.l. (Kurz & Kurz 2013).

Biology:

M. renatae has been found at the edge of dense, deciduous shrubland and tall herb vegetation. Imagines were on the wing in May and June (Kurz & Kurz 2013)

Stages in development:

The early stages are unknown.

Genitalia. Uncus long and relatively slender, with broadly rounded tip; beneath uncus a weakly sclerotized structure with a tuft of long, hair-like setae; accessory claspers shoe-like, at inner surface, at the margin closest to valves with a row of 10 - 13 long, straight, stout and thickened setae, their tips slightly bent; near tip of accessory claspers a group of about 20 moderately long, partly sickle-shaped, stout and thickened setae; valves moderately long, constricted in middle and distinctly spatulate at distal end; valves at inner surface postbasally with an irregular group of more than 10 short setae, the spatulate tip bearing an irregular group of moderately long, straight, stout and thickened setae.

Genitalia. Tergite IX missing; sternite IX much reduced, weakly sclerotized, with very indistinct margins; terminal papillae with band-like, but also very weak sclerotization; receptaculum seminis moderately long, distal half slightly bag-like inflated, distinctly striated.

M. renatae cannot be distinguished externally with certainty from Micropterix italica Heath, 1981 (central and southern Appenines), Micropterix erctella Walsingham, 1919 (Sicily) or reddish golden specimens of Micropterix aruncella (Scopoli, 1763) from the northern or central Apennines, although the former two seem to be allopatric.
In the male genitalia, the species is very similar to M. italica and M. erctella, being distinguished best by the form of the distal part of the uncus-tegumen-complex and by the accesorry clapsers, the latter being distinctly more slender in M. renatae. Furthermore, the setae on the accessory claspers are more numerous in M. renatae (about 30 in contrast to 20 or less in M. italica and M. erctella). M. renatae also has more than 10 postbasal setae at the inner surface of the valves, whereas M. italica has 8 and M. erctella only 3.
In the female genitalia, at least M. aruncella is distinctly different by the shape of the sclerotization of segments IX and X. M. erctella and M. italica also seem to differ by better sclerotized sclerites of segments IX and X, but this character may be variable.

Phylogeny: As described above, the male genitalia of M. erctella, M. italica and M. renatae show some common features, which are interpreted in the sense of a closer relationship. The relation of this species-complex to other complexes in the genus however, remains unclear.
