Description of adults: Examined: 2 . Forewing length: 6.9 - 7.0 mm. Frons distantly scaled, beige; vestiture of hair-like scales on the head beige, brownish above the eyes and at the base of the antennae; labial palpi strongly diverging, 0.55 - 0.6 mm long, smoothly scaled, beige; eyes of oval shape, brown, 0.3 - 0.35 mm in diameter; ocelli missing; antennae filiform, about 2/3 of forewing length, basally beige, distally golden brown shining, the beige colouration dominating at the anterior edge, the golden brown one at the posterior edege; thorax and tegulae dark golden brown, shining; forewings violet-brown, with strong bronzy golden reflections and three whitish to light yellowish, shining spots: A broad, roundish spot at the middle of the inner margin, more or less reaching across half of the wing width; an irregularly triangular spot at the tornus of about half the size, emanating into the tornal fringe; an even smaller, semicircular to triangular spot at the costa at about 4/5; fringe in colouration just like the ground colour except the portion at the tornus; hindwings with broad scales, completely covering the wing membrane, brownish grey with violet shimmer and a delicate, violet-brown shining fringe-line; fringe just like on the forewing, intensively bronzy golden shining; underside in colouration similar to the upperside, the costal spot distinct, the tornal one indistinct, the spot at the inner margin nearly missing; femora of legs partly beige, partly golden brown shining, tarsal elements beige basally, distally golden brown too, sometimes nearly completely beige; foretibia without epiphysis; midtibia with a pair of spurs at the distal end; hindtibia with long, hair-like scales and a pair of spurs each at about 0.55 - 0.6 of its length and at the distal end; abdomen dark, golden brown shining.

Distribution:

The species has been recorded from Spain and the Bristish Isles throughout central Europe, Scandinavia and Finland to European Russia in the north and to Italy and most Balkan countries in the south and southeast. Records are missing so far from Portugal, from the large Mediterranean islands (Corse, Sardinia, Sicily), the Ukraine and southern Russia (Karsholt & Nieukerken, 2004). In Asia, the species is known from the west Siberian plain, the south Siberian mountains and the Amur and Primorye regions (Dubatolov, 2009). Only few data are available regarding the vertical distribution, which reaches at least from the colline level to 1150 m a.s.l. (Kurz et al., 2009).

Biology:

I. oehlmanniella has been found at the edges of predominantely deciduous wood- and bushland with adjacent, extensively utilized meadows. The imagines are on the wing from June to August (Kurz et al., 2009).

Larva. The larva is yellow, with black head. The young larva feeds in mines on Vaccinium-species, later it lives in a case on the ground. The larval stage lasts from August till April (Meeß 1910).

Diagnosis:

The of Incurvaria pectinea Haworth, 1828 and Incurvaria masculella ([Denis & Schiffermüller], 1775) have pectinate antennae, the have hair-like to lanceolate scales on the hindwing upperside, which do not completely cover the wing membrane. In I. oehlmanniella, the antennae are filiform in both sexes, the scales on the hindwing upperside are broad and cover the wing membrane completely.
