Micropterix jeanneli Viette, 1949

(zoological nomenclature: valid name, available)

General information:

Micropteryx jeanneli Viette, 1949b: 50, fig. 2
Type locality: Montenegro, Vusanje (near the border to Albania)
Type: Holotype : Vunsaj [old name for Vusanje], 1400 m, VII; in coll. Muséum National d`Histoire Naturelle de Paris

Synonyms, misspellings, wrong determinations, etc.:
Micropterix corcyrella sensu Heath, 1965b: 645. Misidentification (partim).
The investigation of the type material of both M. jeanneli, as well as Micropterix corcyrella Walsingham, 1919 (Holotype) has already revealed the specific distinctiveness of both taxa (Kurz & Kurz 2012). The discovery of males of M. jeanneli has finally confirmed this assumption.

Scheme of wing pattern:

Description of adults: Examined: 20 , 26 [incl. Holo- and Paratype]. Forewing length: 3.0 - 3.7 mm, 3.6 - 4.4 mm. Head black-brown; vestiture of hair-like scales on the head dirty to dark yellow; antennae dark brown, bronzy golden shining, 9/10 (), respectively, about 3/5 () of forewing length; thorax golden, tegulae purple to purple violet; : Forewings golden with delicate coppery costal margin or proximal half of wing coppery, distal half bronzy golden with silvery-white fasciae: Inner fascia at 1/5, moderately broad, broader at inner margin; at nearly 1/2 a straight fascia, somewhat constricted medially and sometimes anastomizing with inner fascia along costa; at about 3/5 a large, fascia-like costal spot, outwardly oblique, mostly reaching across half of the wing width and sometimes also anastomizing with medial fascia along costa; : Forewings in the proximal half more or less reddish golden to purple-violet, except for the bronzy golden to reddish inner margin, in the distal half bronzy golden to reddish golden; sometimes forewings completely bronzy golden; markings somewhat indistinctly bordered, whitish golden to light golden: At 1/5 a fascia, broad at inner margin, constricted towards costa and not always reaching costa; at about 2/5 a narrow fascia across the whole wing width, slightly bent outwards, often constricted medially; at 3/5 a small costal spot, sometimes indistinct; fringe bronzy golden, lighter outwards; hindwings bronzy golden, tinged coppery to purple; fringe bronzy golden, basally often purple, whitish outwards; legs and abdomen brown, golden shining.

Distribution:

M. jeanneli has been found so far only in the eastern part of Montenegro, close to the borders to Albania, Serbia and Kosovo. Here it flies in a height between 950 and 1450 m a.s.l. (Kurz & Kurz 2014).

The imagines have been found in June and July (Kurz & Kurz 2014). They fly in bushy locations or along wood margins and have been found on flowers of Sambucus nigra and Aruncus dioicus, from 9:00 a.m. to 6:00 p.m. (Christof Zeller, personal observations).

Stages in development:

The early stages are unknown.

Genitalia. Uncus very long and slender, with a knob-like tip; accessory claspers slipper-like, along lower margin with a series of about 15 more or less straight, moderately long, thickened setae with hook-shaped ends; proximally 1 - 2 rows of finer and shorter setae; valves moderately short, stout, distal third bent upwards; postbasally at inner surface three stout and thickened setae; at distal end at inner surface, an irregular group of straight, moderately long, stout and thickened setae.

Genitalia. Tergite IX missing; sternite IX reduced, with indistinct lateral margins; segment X with band-like sclerotization; receptaculum seminis moderately long, proximal half bag-like inflated, with only indistinct striation, not characteristic.

The wing pattern of M. jeanneli is very characteristic and makes the species recognizeable at once. In males, the costal spot at 3/5 is greatly enlarged and outwardly oblique (in Micropterix corcyrella Walsingham, 1919, the spot is at 3/4 and inwardly oblique). In females, this spot is of normal size, sometimes also missing. In both, the normally large costal spot or fascia at about 3/4 is missing. Additionally, M. jeanneli is slightly larger than M. corcyrella. In the male genitalia, M. jeanneli is completely different from M. corcyrella, but shows some similarities to M. facetella. Nevertheless, it is distinguishable from the latter by the more triangle-shaped accessory claspers and the more irregular shape of the valvae. Although M. jeanneli shows no characteristics in the female genitalia, it can easily be separated from both mentioned species. In M. corcyrella, the sclerotized platelets of segment X are very characteristic, whereas in M. facetella, sternite VIII shows a characterístic striation, that misses in M. jeanneli.

Phylogeny: The male genitalia show a close structural relationship to Micropterix facetella Zeller, 1850. If these similarities resemble also a systematic relationship remains unclear, due to the lack of genetic data.
