Scheme of wing pattern:

Description of adults: Examined: 7 , 5 . Forewing length: 3,4 - 3,9 mm; 4,3 - 4,7 mm. Head black-brown, vestiture of hair-like scales on the head dirty white to yellow, between the antennae partly mixed rusty yellow; antennae brown, golden shining, 4/5 (), respectively, 3/5 () of forewing length; thorax bronzy golden, partly coppery, tegulae purple; forewings coppery to purple, the anterior part of the wing sometimes also purplish- violet; base of the wing and inner margin outwards to 1/3 broad bronzy golden, as well as a more or less broad fascia at 1/4, which is confluent with the inner margin; apex of wing and outer margin especially in females also bronzy golden, leaving the distalmost tip of the wing purple; in males, the outer margin is often not developed; the rest of the markings light golden, delicately lined bronzy golden: At nearly 1/2 a straight or slightly bent outwards fascia across the whole wing width, which is sometimes broadening in the middle; sometimes a small costal spot at 2/3; at 3/4 another fascia, reaching across 3/4 of the wing width, small at costa, in the middle very broad, inflated towards the wing base, having a straight outer margin and often being confluent with the bronzy golden outer margin of the wing; fringe coppery to bronzy golden, whitish outwards; hindwings bronzy golden with a coppery to purple tinge; fringe light bronzy golden, purple at its base; legs and abdomen brown, golden shining.

Distribution:

Following Zagulajev (1983), M. montanella is known along the Black Sea coast from Abchasia, Georgia and the Adjarian Republic. The investigated specimens have been caught near Suchumi (Abchasia) and Teberda (russian territory in NW-Caucasus, see Zeller, Kurz & Kurz 2002 and Kurz et al. 2009). The vertical distribution reaches from near sea level (150 - 200 m in Adjaria) up to about 2400 m in Teberda.

Biology:

There are no data available concerning the biology of the species. The moths are on the wing in June (90% of all data) and early July (10% of all data; see Kurz et al. 2009).

Stages in development:

The early stages are unknown.

Genitalia. Uncus long and moderately slender, with a broadly rounded tip; tegumen distinctly separated from vinculum, its distal margin triangle-shaped with a fold on the posterior margin, that covers the basis of the accessory claspers; near this fold some long, outwardly directed setae; accessory claspers pouch-like, directed ventrally, their lower margin with a row of 8 long, undulating stout setae with sickle-shaped tips; valvae short and stout, somewhat constricted medially, their tips shoe-like bent upwards; at the inner surface postbasally with some setae, at the tips with 2 - 3 rows of short spinoid setae.

Genitalia. Tergite IX missing; sternite IX reduced, constricted medially, not of diagnostic value; papillae anales band-like sclerotized; receptaculum seminis long and slender, the proximal part bag-like enlarged.

M. montanella can be distinguished from the most variable Micropterix maschukella Alpheraki, 1870 by having a somewhat greater forewing length, more sharply defined markings and especially by the quite characteristic fascia at 3/4 and the bronzy golden outer margin. If this bronzy golden colouration is missing, which is frequently the case in males, a genitalic investigation is necessary.
The male genitalia of M. montanella are of high diagnostic value and unmistakable. The female may be distinguished from M. maschukella also by the long and slender receptaculum seminis, which is distinctly shorter in M. maschukella.

Phylogeny: No DNA-investigations habe been performed so far in order to establish the phylogenetic relationship of M. montanella within the genus. Based on characters of the male genitalia therefore, it is assumed, that M. montanella forms a complex of species with Micropterix islamella Amsel, 1935 from the Middle East and Micropterix granatensis Heath, 1981 from Spain. An apomorphy of this complex seem to be the ventralwards bent accessory claspers and the elongation of the uncus (the latter character being a parallelism to other species-complexes). On the other hand, the subdivision of the whole apparatus in two compartments, consisting of uncus, tegumen and accessory claspers on the one hand and vinculum and valves on the other hand, as well as the relatively short and stout valves are regarded to be plesiomorphic, placing this species-complex among the most primitive members of the genus.
