Until recently only few caddisfly records have been reported from Sharr, a mountainous area recognized as one of the most important biodiversity hotspots in the Balkan Peninsula. In this paper we report 27 species collected from May to November 2013 at seven sampling stations in a territory which is a recent addition to the existing Sharr National Park, and adjacent to it. Three species are first records for the caddisflies of the Republic of Kosovo: Limnephilus hirsutus (Pictet, 1834)¸ Potamophylax latipennis (Curtis, 1834) and Oecismus mucidus McLachlan, 1876. This investigation also contributes to the range extensions of several rare and endemic species of the Balkan Peninsula and Europe, such as: Rhyacophila fischeri Botosaneanu, 1957, Rhyacophila palmeni McLachlan, 1879, Allogamus auricollis braueri Kolenati, 1859, Annitella triloba Marinković Gospodnetić, 1957, Chaetopteryx stankovici Marinković Gospodnetić, 1966 and Notidobia melanoptera Stein, 1863, amongst others.
