Scheme of wing pattern:

Description of adults: Examined: 16 , 37 . Forewing length: 2.3 - 2.8 mm 2.4 - 2.9 mm. Head black-brown, vestiture of hair-like scales on the head light yellow; antennae brown, golden shining, 4/5 (), respectively, 2/3 () of forewing length; thorax bronzy golden; tegulae purple violet; forewings purple to bluish violet, with light golden, delicately bronzy golden bordered markings: At 1/4 a triangular fascia, broad at the inner margin, mostly not reaching the costa; at 1/2 a moderately broad, straight fascia across the whole wing width, sometimes somewhat constricted towards the costa; at 3/4 a quadrangulate spot from costa towards the middle of the wing, the outer fourth of the wing more or less, often almost completely bronzy golden, the bronzy golden colouration confluent with the spot at 3/4 and leaving the outermost tip of the wing purple; near the costal margin a small golden spot at the base; fringe bronzy golden; hindwings bronzy golden, fringe of the same colouration; legs and abdomen brown, golden shining.

Distribution:

M. minotaurella is known only from the type locality in the eastern part of the isle of Crete and from a single female from the central part of the island (provinve of Rethymno). The type locality has a height of about 400 m a.s.l, whereas the second known localty is situated in about 430 m a.s.l. (Kurz & Kurz 2012).

genitalia. Uncus short, knob-like; tegumen elongated, bow-like bent distalwards; at the posterior margin of the tegumen, close to the onset of the uncus, two short rows of fine, short setae; inside the tegumen a bilobed, comb-like structure, projecting distalwards, with about 13 ventrally directed teeth; accessory claspers triangle-shaped, broad at the basis, tapering to one point distally, which bears a group of about 5 short, modified, stout and thickened setae; this group is prolonged along the ventral margin by a row of about 10, relatively long, partly bent, stout and thickened setae and slightly dorsally a second row of about 6 short, T- to Y-shaped, stout and thickened setae of extreme width; basally of the ventral row of setae, close to the onset of the accessory claspers, a minute projection bearing three moderately long, stout and thickened, more or less straight setae, as well as a conspiciously broad, blade-like, stout and thickened seta; the small projection is followed proximally by a small, broadly spatulate lobe; valves relatively long and slender, slightly bent upwards and slightly constricted medially; postbasally a small group of short setae; the distal half with 1 - 2 rows of short, spinoid setae as well as a row of long, fine setae.

genitalia. All sclerites only weakly sclerotized; tergite IX missing; sternite IX weakly sclerotized, much reduced, with partly indistinct margins; papillae anales (segment X) with band-like sclerotization; receptaculum seminis very short, slender, with genero-typical, but weak striation over its whole lenght.

This species is the only Micropterix-species so far known from Crete.
The structure of the male genitalia implicates a close relationship to Micropterix kardamylensis Rebel, 1903 and Micropterix lakoniensisi Heath, 1985, respectively. The species from Crete differs from both by the small size of the whole apparatus, from M. lakoniensis also by the shape of the accessory claspers (more slender in M. lakoniensis) and the row of spinoid setae on the valves, which reaches nearly 2/3 of the length basalwards in M. lakoniensis, but only half of the length in the species from Crete. In M. kardamylensis, the setae of the accessory claspers are less modified (extremely broad T- to Y-shaped in the species from Crete). In the female genitalia, the species differs from both M. kardamylensis and M. lakoniensis by the weak sclerotization of all sclerites and by the smaller size of all parts.

Phylogeny: See discussion under Micropterix kardamylensis Rebel, 1903.

Worth knowing:

The official description and naming of the species will be published in the planned volume about Micropterigidae in the "Microlepidoptera of Europe"-series.
