title: A new species of Limnephilidae (Insecta: Trichoptera) from the Western Alps (Insecta: Trichoptera).
abstract: A new species of the alpine caddisfly genusConsorophylax(Trichoptera, Limnephilidae, Stenophylacini) and the female of the recently describedC. vinconiGraf & Malicky 2015 are described. The new speciesC. lepontiorumsp. nov.is a microendemic of the South-Western Alps and differs from its congeners in the shape of the superior and inferior appendages and the unique setation of the aedeagus, absent in all otherConsorophylaxspecies. The female ofC. vinconiis characterized by the unique formation of the anal tube. Potential effects of alpine orogenesis, phenology and climatic oscillation on speciation of aquatic insects inhabiting high-altitude habitats are discussed. The description ofC. lepontiorumsp. nov.accentuates the significance of the Western Alps as harbours of aquatic insect biodiversity, and demonstrates the necessity of faunal and taxonomic studies in Europe - a supposedly well-explored region.
