Scheme of wing pattern:

Description of adults: Examined: 2 , 6 . Forewing length: 3.4 - 3.85 mm, 4.1 - 5.0 mm. Head black-brown; vestiture of hair-like scales on the head dirty yellow; antennae dark brown, bronzy golden shining, 4/5 (), respectively, 3/5 () of forewing length; thorax golden to bronzy golden, distally sometimes with a few purplish scales; tegulae purple to purple violet, proximally sometimes bronzy golden; forewings brownish golden to purple violet, inner margin with a broad, bronzy golden streak, reaching from the basis to the fascia at 1/2; outer margin and apex bronzy golden too, leaving only the outermost tip of the wing purple, the bronzy golden colouration dissolved to spots towards basis of wing; markings golden to whitish golden, delicately, but diffusely bordered bronzy golden; At 1/5 a moderately broad fascia, straight to outwardly oblique towards costa, reaching from costa to bronzy golden inner margin; this fascia mostly bronzy golden coloured and only slightly brighter in its centre; a distinctly outwardly bent, moderately broad fascia across the whole wing width at 1/2; at 2/3 a conspicous costal spot; at slightly more than 3/4 a moderately broad to broad, elongate to triangle-shaped spot, reaching from costa inwardly oblique across 2/3 of the wing width, in males sometimes even reaching the outer margin; fringe bronzy golden, basally also purple, whitish outwards; hindwing bronzy golden, distally more or less tinged purple; fringe bronzy golden, whitish outwards; legs and abdomen brown, bronzy golden shining.

Distribution:

To present knownlewdge, the species seems to be endemic to the northern Apennines and has been found only in the provinces of Emilia Romagna and Tuscany. Records about vertical distribution are poor and reach from 430 - 1500 m a.s.l. (Heath 1963, Kurz & Kurz 2010).

Biology:

M. zangheriella inhabits clearings and edges of beech- and mixed beech-forests, having well structed underwoods. Furthermore, it has been found among bushland, where the animals were feeding on the pollen of Sambucus nigra. Here, they have been found in competition to Micropterix aruncella (Scopoli, 1763). The imagines are on the wing in May and June, eventually also early July (Kurz & Kurz 2010).

Stages in development:

The early stages are unknown.

Genitalia. Uncus moderately long, tip broadly rounded; at the posterior margin of the tegumen a row of moderately long, distally directed, stout setae; accessory claspers distinctly offset, broad at basis, narrowing distally; at their posterior margin a row of 9 - 10 long to very long, dorsalwards bent, otherwise straight, stout and thickened setae; slightly proximally, a second row at the inner surface of shorter, strongly modified, Y- to T-shaped, stout and thickened setae; ventrally offset, a large sickle-shaped seta on a long process; valves moderately long and slender, medially distinctly constricted, the spatulate distal third at inner surface with a larger group of short to moderately long, stout and thickened setae in 2 - 3 irregular rows and about 6 longer setae at distal end; valves at inner surface postbasally with a group of longer setae and two longer, straight, stout and thickened setae.

Genitalia. Tergite IX missing; sternite IX reduced, well sclerotized, but with somewhat indistinct lateral margins; papillae anales with band-like sclerotization of equal width; receptaculum seminis moderately long, the proximal 2/3 of its length bag-like inflated, distinctly striated.

Externally, M. zangheriella is nearly indistinguishable from the sympatric Micropterix schaefferi Heath, 1975, but also from Micropterix vulturensis Heath, 1981 from the central and southern Apennines. The latter is presently not known to be sympatric with M. zangheriellla, but the distribution ranges of both species are only imperfectly known. M. schaefferi may be distinguished from M. zangheriella by the form of the inner fascia, which is of equal width from costa to inner margin in M. zangheriella, but distinctly constricted towards the costa in M. schaefferi. Furthermore, the males of M. zangheriella have a distinctly bigger spot at 3/4 than the males of M. schafferi (the latter character is of no diagnostic value in females !). Normally, M. zangheriella is slightly smaller than M. schaefferi.
The male genitalia of all three species are distinctly different from each other. M. zangheriella can be recognized by the stout and thickened setae at the distal margin of the tegumen (between uncus and accessory claspers) and by the form of the accessory claspers.

Phylogeny: M. zangheriella seems to be a "basic" species among its relatives, with richly developed structures of the male genitalia. It is quite similar in these structures to Micropterix hartigi Heath, 1981 and Micropterix tuscaniensis Heath, 1960, especially in the accessory claspers. These bear highly modified, thickened setae along the ventral margin, the basalmost seta being distinctly offset from the others and partly twisted. The uncus is similarly bulky in all three species, but the valves are more slender in M. zangheriella and in contrast to M. tuscaniensis. In that latter species, the valves are significantly inflated in the distal third. In the female genitalia, the sclerotization of the papillae anales is of equal width, whereas in the other two species, it is distinctly broader in the middle.
