Scheme of wing pattern:

Description of adults: Examined: 15 (incl. slide of holotype), 5 . Forewing length: 2.5 - 3.6 mm; 3.6 - 4.0 mm. Head black, vestiture of hair-like scales on the head dirty ochre to dark yellow; antennae dark brown, golden shining, 4/5 (), respectively, slightly more than 1/2 () of forewing length; thorax bronze golden, tegulae bronze golden, posteriorly purple violett with single bluish scales; forewings bronze golden to coppery, at the distal part of the costa and at the apex slightly tinged purple; wing markings silvery white, sharply defined; at 1/4 a narrow, straight fascia across the whole wing width; a similar fascia at slightly more than 1/2, slightly oblique outwards towards the inner margin; at 3/4 an elongate, more or less kidney-like spot, from costa inwardly oblique towards the center of the wing; sometimes a light golden suffusion along the outer margin; fringe golden, at the apex purple basally; hindwings coppery; fringe coppery, outwardly golden; legs and abdomen dark brown, golden shining.

Distribution:

Following Heath (1965b), the species is distributed in Greece, Bulgaria and Macedonia. Karsholt (2004) also reports the species from Slovenia, but this record seems to be doubtful. Both authors regard Micropterix jeanneli Viette, 1949 from Montenegro to be synonymous with M. corcyrella, but this has been shown to be erroneous. Confirmed specimens are from Macedonia and Greece. Vertically, specimens have been found between about 100 and 600 m a.s.l. (see Kurz & Kurz 2014).

Biology:

There aren´t any data available concerning the biology of M. corcyrella, except that the imagines have been found in bushland. They have been caught in April and May (Kurz & Kurz 2014).

Stages in development:

The early stages are unknown.

genitalia. Uncus moderately long and slender; accessory claspers reduced, bent upwards inside the tegumen; on their posterior margin about 10 inwardly directed, long and stout, thickend setae with hook-like tips; distal margin of the tegumen on both sides enlarged to a sclerotized lobe, bearing on its anterior margin two rows of stout and thickend setae; proximad, the row consists of very short, unmodified setae, whereas the distal row consists of 16 - 18 very long, straight setae, which are more or less broadend at their tips; beneath these lobes and somewhat proximad a second pair of small sclerotized lobes, bearing similar rows of stout an thickend setae; here, the distal row consisting only of 5 very long setae; valves moderately short, stout, constricted in the middle, their distal ends spatulate und slightly bent upwards; at the inner surface of the valves postbasally two short and stout, thickend setae, their spatulate tips with two rows of short to moderately long, stout and thickend seate, as well as some longer setae.

genitalia. Tergite IX missing; sternite IX strongly reduced; constricted in the middle, weakly sklerotized, with indistinct lateral and proximal margins; papillae anales with a pair of characteristic, paddle-like and well sclerotized platelets; receptaculum seminis moderately long and very slender, distinctly constricted at about 1/4 of its length; striation of the receptaculum only weakly visible.

Micropterix corcyrella cephaloniensis Kurz, Kurz & Zeller, 2004 from the Ionian island of Cephalonia resembles the typical subspecies closely with respect to male and female genitalia, but has females without any wing markings. M. corcyrella corcyrella is very similar to the Italian species Micropterix erctella Walsingham, 1919, Micropterix italica Heath, 1981 and Micropterix renatae Kurz, Kurz & Zeller, 1997, but also to the central Italian forms of Micropterix aruncella (Scopoli, 1763). Of them, only M. aruncella may be found within the distribution range of M. corcyrella. Nevertheless, the male and female genitalia of M. corcyrella are very distinctive and make the species unmistakable.

Phylogeny: There aren´t any differences to Micropterix corcyrella cephaloniensis Kurz, Kurz & Zeller, 2004 with respect to the male and female genitalia. Therefore, the latter is assumed to be of subspecific state to typical forms.

Remarks. Heath (1965b) has synonymized Micropterix jeanneli Viette, 1949 from Montenegro with M. corcyrella. This taxon however, is distinctly larger than M. corcyrella, having about 2 mm more in wingspan. Furthermore, the ground plan of its wing pattern is distinctly different from that of M. corcyrella, in that M. jeanneli shows the small costal spot at 3/5 (identical with the spot, that is found in other species between the fascia at 1/2 and the spot at 3/4), and misses the spot at 3/4, whereas M. corcyrella has a prominent spot at 3/4, but never the small costal spot at 3/5. Furthermore, recently discovered males have been shown to be completely different in genitalia morphology.
