Scheme of wing pattern:

Description of adults: Examined: 5 , 1 . Forewing length: 3.7 - 4.0 mm, 4.1 mm. Head black-brown; vestiture of hair-like scales on the head dirty white to yellow; antennae dark brown, golden shining, about 4/5 (), respectively, slightly more than 1/2 () of forewing length; thorax bronzy golden, distad slightly reddish; tegulae reddish bronzy golden to purple; forewings bronzy golden at the basis, otherwise reddish golden to purple, in the distal third mixed bronzy golden; especially in , with bronzy golden colouration along apex and outer margin, leaving only the outermost tip of the wing purple; markings light golden, delicately bronzy golden bordered: At nearly 1/4 a fascia across the whole wing width, somewhat constricted towards the costa, slightly bent proximad in the middle, broader at the inner margin; a slightly narrower fascia across the whole wing width at 1/2, medially distinctly bent outwards; a small costal spot at 3/5; at 3/4 a spot across 3/4 of the wing width, narrow at costa, in only touching costa, of variable shape; the spot may be roundish, broad, pear-like or even inflated, triangle-shaped; fringe basally reddish golden, whitish outwards; hindwings bronzy golden, especially apically tinged purple; fringe basally coppery, light golden outwards; legs and abdomen dark brown, golden shining.

Distribution:

According to Heath (1981b), the species is distributed in the central and southern Apennines (Latio, Basilicata: Lucania), from near sea level up to 1200 m. Furter records for Tuscany and Abruzzo are given by Zeller et al. (2002), for Puglia by Kurz & Kurz (2010).

Like most other species with purple ground colour, M. hartigi is associated with woodland. Following Kurz & Kurz (2010), the species inhabits clearings and edges of deciduous woodland with richly developed herbal vegetation (e.g. Urtica, Rubus, Galium ssp.), as well as similar biotops mixed with evergreen shrubs (Quercus ilex), but also hedges of Rose. The imagines have been found on the blossoms of an unidentified species of Rosa. The flight period lasts from early April to mid June depending on the altitude (Heath 1981b, Kurz & Kurz 2010).

Stages in development:

The early stages are unknown.

genitalia. Uncus moderately long and slender, rounded at the tip; beneath the uncus, inside the tegumen, a downwardly bent, membraneous lobe at each side, bearing long, hair-like setae; an additional small lobe at each side at the distal margin of the tegumen, bearing 5 - 6 distally directed setae; accessory claspers irregular, triangle-shaped, at the distal margin, close to the tip with a group of strongly modified, T- to Y-shaped, stout and thickened setae at the inner surface; directly at the tip another group of short, more sickle-shaped, stout and thickened setae; at the middle of the margin opposite to the valves two moderately long, straight, at the tip hook-like bent, stout and thickened setae; another 1 or 2 similar setae, distinctly discharged proximally; valves slender, long, medially constricted, the distal third slender, shoe-shaped, slightly bent upwards; valves at the inner surface, close to the lower margin with a conspicous and very characteristic thorn-like seta at about 1/3 of its length, with some stout setae postbasally and at the basis of the distal third with a group of 15 - 20 moderately long, straight, stout and thickened setae; at the distalmost tip of the valves a row of long, thin setae.

genitalia. Tergite IX missing; sternite IX strongly reduced, constricted medially and only very weakly sclerotized; terminal papillae with a strong sclerotized band; receptaculum seminis moderately long, slender, the proximal two thirds an elongated sac; receptaculum seminis with distinct striation.

In most cases, M. hartigi can be distinguished from the more violet species like Micropterix tuscaniensis Heath, 1960 or Micropterix allionella (Fabricius, 1794) by its reddish golden ground colour and its light golden markings. In M. tuscaniensis, the fascia at 1/4 is distinctly triangle-shaped, with a broader basis at the inner margin, tapering to one point at the costa. M. allionella on the other hand, normally has broader fasciae than M. hartigi.
The male genitalia of M. hartigi are very characteristic, and normally, a maceration of the abdomen is unnecessary for proper identification. In the females, the sclerotization of sternite IX seems to be distinctly weaker than in M. allionella, although the number of investigated specimens is still to poor.

Phylogeny: M. hartigi probably belongs to a complex of species, which is characterized by the following feature of the male genitalia: The one or two anteriormost setae on the ventral margin of the accessory claspers are distinctly offset from the others in the row. Among these species, M. hartigi is believed to be one of the more primitive members, due to the presence of distinct lobes between uncus and accessory claspers. For further details see section diagnosis under M. allionella and Micropterix zangheriella Heath, 1963.
