First record of <i>Hydroptila kalonichtis</i> Malicky, 1972 (Trichoptera, Hydroptilidae) from the Western Balkans

Adult caddisflies were collected from the Bistrica River and Dërmjak Stream in Kosovo, during June 2020 and June 2023. Thirteen species were found, belonging to the following families: Rhyacophilidae, Glossosomatidae, Hydroptilidae, Philopotamidae, Polycentropodidae, Psychomyiidae, Limnephilidae and Goeridae. Hydroptila kalonichtis Malicky, 1972, a rare species described from Greece, is reported for the first time from the Western Balkans. In addition to this, this study contributes to the expansion of the known distribution area of two other rare species endemic to the Balkan Peninsula; Polycentropus slovenica (Malicky, 1998) and Tinodes janssensi Jacquemart, 1957.
