Contribution to the knowledge of the caddisfly (Insecta: Trichoptera) fauna of the eastern part of Kosovo with the first record of <i>Wormaldia juliani</i> Kumanski, 1979

Adult caddisflies were collected with ultraviolet light traps during June and September 2017 in two localities in eastern Kosovo. We found 17 species in total, belonging to the following families: Rhyacophilidae, Hydropsychidae, Psychomyiidae, Philopotamidae and Limnephilidae. At the first sampling station we registered the species Wormaldia juliani Kumanski, 1979 for the first time from Kosovo. The male genitalia of these specimens generally correspond with the described species, with slight differences in harpagos and tergite VIII, which can be explained by geographical variability. We also found few other rare species such as Tinodes janssensi Jacquemart, 1957 and Rhyacophila macedonica Valladolid, Karaouzas &amp;amp; Ibrahimi, 2022 among other.
