2 (1) Wings not rudimentary, not lanceolate, surface pubescent, also beyond venation. 3 (4) Wings squamiform small, with some long bristles on surface. Venation very rudymentary or absent. 4. Subfamily: Limnephilinae partim 4 (3) Wings normal, venation not rudimentary. 5 (6) Discoidal cell of hind wings open towards apex (not bordered by a cross-vein), or radial vein of fore wings joining costa with a cross-vein, in which also subcosta joins. 2. Subfamily: Apateniinae 6 (5) Discoidal cell of hind wings closed. 7 (8) Median branches of hind wings originating comparatively near to each other, the so-called M-3+4 - Cu-1, that is, cross-vein between third and fourth lateral branches of media and first cubitus short. 3. Subfamily: Drusinae partim 8 (7) Median branches of hind wings originating comparatively far from one another, cross-vein between M+3+4 - Cu-1 long, arched transversally. 9 (10) Tiridial and third anal cell of hind wing with a row of thick bristles. 3. Subfamily: Drusinae partim 10 (9) Surface of tiridial and third anal cell of hind wing without row of bristles. 11 (12) Wings red, wide and rounded. From discoidal cell of fore wing a lateral branch originating, decurrent almost parallel with lateral branch of radial vein above discoidal cell; parallel part almost as long as one-third of length of discoidal cell. Inner side of lower genital plate of males without chitinous spines. Vulval spine of females trilobate. 1. Subfamily: Dicosmoecinae 12 (11) Wing different. From discoidal cell of fore wing no lateral branch originating, if so length of its given part not reaching one-third of length of discoidal cell. 4. Subfamily: Limnephilinae partim 1. Subfamily: Dicosmoecinae Tibial spurs: 1, 3, 4. First tarsal joint of fore leg longer than second. Apex of fore wing widely rounded discoidal cell extremely long, at least five times as long as wide and three times as long as basal part of lateral branch of radial vein. Fourt of its endforks undeveloped. - One genus of the family living in Europe. — Radial vein of fore wing undulated in apical third, immediately before joining costa (Fig. 1). Hind wing shorter than fore wing, apex widely rounded, relatively pubescent. Discoidal ceU comparatively long (Fig. 2). - Type-species: parvula BANKS 1916. A single species living in Europe: dubia STEPHENS, 1837, (Anabolia) (Central and North Europe, Japan) Ironoquia BANKS, 1916
