Micropteryx idae Rebel, 1902

(zoological nomenclature: synonym, available)

General information:

Micropteryx idae Rebel, 1902: 110
Type locality: Greece, Peloponnes, Taygetos, Kambos
Type: Holotype : "Morea merid.; Kambos: Taygetos; V.1901 Holtz"; [red label] "TYPE"; "Micropteryx idae Rbl.; Type `02"; in coll. NHMW

Synonyms, misspellings, wrong determinations, etc.:
The status of M. idae is still uncertain. Heath (1965b) has synomymized the taxon with Micropterix myrtetella Zeller, 1850 on the basis of males from Larissa, Greece, which completely lack any markings, but are identical in the male genitalia with typical M. myrtetella. In fact, there is a broad range of externally intermediate forms throughout the Balcans with more or less reduction of the golden markings combined with a shift from purple to bronzy golden ground colour. The extreme forms regarding loss of wing markings ("typical" M. idae) seem to be confined in distribution to eastern and south eastern Greece.

Scheme of wing pattern:

Description of adults: Examined: 3 , 1 [incl. Holotype]. Forewing length: 2.3 - 2.5 mm; 2.6 mm. Head black-brown; vestiture of hair-like scales on the head dirty white to brown; antennae brown, golden shining, 4/5 (), respectively, 2/3 () of forewing length; thorax golden, tegulae coppery; forewings unicolorous coppery or bronzy golden to light bronzy golden, reddish golden to purple in the basal third, with light golden markings: At the inner margin, at about 1/4 a broad, triangle-shaped spot, reaching across more than half of the wing width; rudiments of a median fascia may be indicated by light golden spots at 1/3 at the costal and at 1/2 at the inner margin; fringe golden, whitish outwards; hindwings bronzy golden, slightly tinged purple; fringe bronzy golden, lighter outwards; legs and abdomen brown, golden shining.

Distribution:

Specimens resembling the above description, have been found so far only in eastern and south eastern Greece in a height from 560 - 820 m a.s.l. (Kurz & Kurz 2011). Specimens, which are intermediate in wing markings between the taxa M. idae and M. myrtella are frequently found throughout most Balcan countries.

Biology:

The taxon has been found at the edge of evergreen shrubs, feeding on the pollen of blossoming Cistus-species (Cistus creticus and, probably, Cistus salviifolius). Specimens have also been found on partly shady, rocky slopes, feeding on not identified, herbaceous plants with numerous small, yellow blossoms. Imagines have been found on the wing in May (Kurz & Kurz 2011).

Stages in development:

The early stages are unknown.

Genitalia. Uncus short with broad and rounded tip; beneath the uncus, inside the tegumen, a structure with hair-like setae; accessory claspers very broad; at their inner surface, along the posterior margin, a row of short, straight, distally slightly bent, stout and thickened setae; near the margin close to the valves, slightly proximad to this row, a second one of about 5 - 6 short, straight, stout and thickened setae; valves moderately long, slender, somewhat constricted medially, the distal fourth spatulate to nearly triangulate and slightly bent upwards; valves at their inner surface with a row of 3 - 4 moderately long, nearly straight, stout and thickened setae from postbasal to the middle and with a row of 6 - 7 straight, short, stout and thickened setae, as well as some normal setae at the distal fourth.

Genitalia. Tergite IX missing; sternite IX much reduced and only weakly sclerotized; papillae anales in the form of a broad band, well sclerotized; receptaculum seminis long and very slender, the proximal half slightly inflated and distinctly striated.

The reduced wing markings and the small size make the taxon M. idae well distinguishable from all other taxa of the genus. Intermediate specimens to typical Micropterix myrtetella Zeller, 1850 may occur throughout the Balcans. Specimens devoid of any markings may resemble somewhat females of Micropterix aruncella (Scopoli, 1763) in both the typical form with yellow vestiture of hair-like scales on the head and the f. atricapilla Wocke, 1877 with black-brown vestiture of hair-like scales on the head. Nevertheless, M. aruncella normally is distinctly larger in wingspan than M. idae and is readily distinguishable in male and female genitalia.
