New Records for the Caddisfly Fauna (Insecta: Trichoptera) of the Karadak Mountains, Western Balkans

Abstract

We collected adult caddisfly specimens occasionally during 2017 at the Karadak Mountains, which remains one of the least explored mountainous areas in the Western Balkans. Here we report 15 species, three of which are first records for the Karadak Mountains and Republic of North Macedonia: Rhyacophila bosnica Schmid, 1960, Tinodes kimminsi Sykora, 1962 and Stenophylax permistus McLachlan, 1895.
In addition to this, new localities of R. bosnica from Kosovo are reported. We discuss the distribution and ecology of this rare endemic species, including the first noted winter activity of the adult stage.
