Habit:

Description of adults: Examined: 23 , 25 . Forewing length: 2,8 - 3,8 mm, 3,9 - 4,5 mm. Head black-brown; vestiture of hair-like scales on the head dirty white to yellow; antennae dark brown, golden shining, 3/4 (), respectively, 1/2 () of forewing length; thorax bronzy golden, distally with single purple violet scales; tegulae bronzy golden, distally with single purple violet scales too; forewings bronzy golden to purple with very indistinct, bronzy golden to whitisch golden markings: At about 1/5 a moderately broad fascia from the costa slightly inwardly oblique and fused with the broad, bronzy golden inner margin; the bronzy golden colouration at the inner margin basally slightly purple tinged and reaching to the medial fascia at 1/2; this fascia moderately broad, indistinctly whitish golden near the costa, reaching across the whole wing width and slightly oblique towards the inner margin; at nearly 3/4 a broad, oval spot, barely reaching costa and outer margin and also indistinctly whitish golden in the upper third; fringe bronzy golden, basally also purple; hindwings bronzy golden, apically tinged purple; fringe bronzy golden, lighter outwards; legs and abdomen brown, golden shining.

Distribution:

M. granatensis has been found so far only in southern Spain, in the provinces of Granada, Malaga and Alicante (Heath 1981, Kurz & Kurz 2011). Vertically, there is only one record available (960 m, see Kurz & Kurz 2011).

Biology:

According to Heath (1981), one male has been found on a blossom of Cistus. Huemer and Wieser have found the species on blossoming Fraxinus ornus together with Micropterix ibericella Caradja, 1920 (pers.comm.). Imagines have been found on the wing in May (Kurz & Kurz 2011).

Stages in development:

The early stages are unknown.

Genitalia. Uncus long, club-shaped at the tip, its connection to the tegumen very narrow; the posterior margin of the tegumen enlarged, infolding partly the accessory claspers, then bent downwards in a bow and forming a short duct for the aedeagus by fusion of the two sides in the middle; accessory claspers slender, bent downwards, at the margin opposite the uncus with some setae, at the tip with 3 or 4 moderately long, posteriorly directed, stout and thickened setae, which are sickle-shaped at their tips; valves short, stout, somewhat constricted in the middle, at their inner surface postbasally with some setae, at their spatulate posterior ends with 2 - 3 rows of short, straight, stout and thickened setae.

Diagnosis:

Within its distribution range in Spain, we do not know any other similar species.

Phylogeny: With respect to the very distinctive male genitalia, the species seems to be allied to Micropterix maschukella Alpheraki, 1870 from the Caucasus and Micropterix islamella Amsel, 1935 from the Levant, especially regarding the elongated uncus, the form of the accessory claspers and the bulky valves.
