Description
Adult (Figs 1, 2). Forewing length: male (n=8), 7.0–8.0 mm; female (n=2), 5.5–6.5 mm.
Head covered with yellowish scales, frons whitish; eyes hemispheric, black; labial palpi bright yellowish brown, apically whitish; antennae in both sexes delicately ciliated, brown, covered with small white scales in fresh specimens; thorax brownish black with golden shine; abdomen grey-brown; ground colour of forewing upper side black-brown with a distinct white wing pattern consisting of: a short longitudinal basal streak, two fasciae developed as small narrow bands, inner fascia at 1/3 of the wing length runs from costal to dorsal margin (costal nearer to wing-base), outer fascia at 3/4 is arranged in the opposite direction, costal margin at 1/2 with a subtriangular spot, a short horizontal streak in the marginal area near the apex of the wing, fringes basal brownish black, distal white. Underside with the same pattern, but more blurred. Hindwings shiny grey, fringes basally dark grey, distal part brighter grey to white; legs dirty white to beige, tibiae and tarsi brownish beige, fore-tibia without epiphysis, hind-tibia with a pair of pre-apical spurs, with a long tuft of hair-like scales and a pair of long apical spurs.

Male genitalia (Fig. 3). Uncus and tegumen short, forming a trapezoid plate, posterior margin of uncus medially concave forming a double lobed structure; socius distinctly sclerotized, club-shaped, long, distally widened; transtilla with distinct medial knob and strongly sclerotized lateral arms; sub-medial anterior projections relatively long, finger-shaped and of equal width, ending in an edge; valva short and robust; costal margin slightly concave; cucullus hirsute, with a set of distinct spines along the margin, apex hirsute and rounded; vinculum V-shaped, broad and short, distal end broad and rounded.
Female genitalia (Fig. 4). Pre-genital segments. Sternum VII as well as tergum VII of rectangular shape. Posterior part of ovipositor triangular, tip rounded, lateral margins concave with two steps; apophyses posteriores and anteriores both relatively long, with blunt ends; ductus bursae as well as bursa copulatrix short, the latter bulky and without signa; ductus spermathecae with several convolutions.
Diagnosis
Due to the unique coloration and pattern of the forewings of both sexes, I.stangei can be easily separated from all other members of Adeloidea.
Bionomics
The biology of I.stangei is unknown; the host plant as well as primary stages are still undiscovered. Huemer (1991)[2] assumed that adults are active in the early morning hours before sunrise, similar to some other alpine incurvariids such as e.g. I.vetulella (Zetterstedt, 1839). However, Deutsch (2012)[3] also reported attraction to artificial light. The poorly known life habits likely explain the small number of observed individuals. The adults were found in the second half of July, mainly at the border zone between the subalpine shrubs and alpine meadows from about 1700 to 2500 m elevation (Huemer 1991[2]) (Fig. 5). Deutsch (2012)[3], however, found a single male at a lower elevation (1250 m), which is suspected to have been drifted from its natural habitat.
Distribution
The species is endemic to the south-eastern Alps: Julian Alps: Slovenia, Goriška (Carnelutti 1978[4]; Habeler and Gomboc 2005[5]; Govedič and Lesar 2010[6]; Rebel 1907[7]); Carnic Alps: Italy, Friuli-Venezia Giulia (Huemer 1991[2]; unpublished record), Austria, East Tyrol (Deutsch 2012[3]); Dolomites: Italy, South Tyrol (Rebel 1903[8]); Orobian Alps: Italy, Lombardia (unpublished record).
Remarks
Despite of a personal search by PH, the holotype could not be traced at NHMW. The Rebel collection only contains a label of the species but without any evidence of the specimen, even a pinhole is absent.
