We present the first preliminary inventory of Trichoptera taxa in the Aegean and Adriatic Sea basins in Kosovo that have previously received poor and fragmentary attention. Adult caddisflies were collected using ultraviolet (UV) light traps in 13 stations in areas of the Aegean Sea and Adriatic Sea drainage basins in Kosovo. Nineteen species out of 82, reported in this article, are first records for the Kosovo caddisfly fauna. Five genera are recorded for the first time in Kosovo: Brachycentrus, Ecclisopteryx, Psilopteryx, Thremma, and Oecetis. During this investigation, we found several Southeastern European endemic and rare species whose previous known distribution was limited to particular areas of this region, as well as other species whose distribution is considerably enlarged by this investigation: Polycentropus ierapetra, Polycentropus irroratus, Chaetopteryx stankovici, Drusus schmidi, Drusus tenellus, Potamophylax goulandriourum, Oecetis notata, and Notidobia melanoptera. Even though this article is a result of a limited sampling effort, it increases the number of Trichoptera taxa recorded for the Republic of Kosovo to 131.

Adult caddisflies were collected from 12 stations in the Black Sea basin in Kosovo using UV light traps. Sixty-five of the seventy-six species reported in this

The Balkan Peninsula is known for its high species diversity, but it is also one of the least known areas of Europe. Many previously inaccessible regions lack reliable faunistic records. There are especially few data available for the highly diverse aquatic insects of the region. To help fill the gap, we conducted an extensive survey to map the Trichoptera fauna of the Republic of Kosovo, an area where faunistic records are extremely scarce. Adult specimens were collected during 2009 and 2010, with light traps and entomologic nets. Of 84 Trichoptera species identified from the 21 investigated stations, 15 belong to the genus Rhyacophila. This makes the genus the most species-rich in Kosovo. Rhyacophila fasciata and R. tristis are widespread in many streams and rivers all over the country, while R. balcanica, R. trescavicensis, R. obtusa and R. bosnica have limited distribution. Ten Rhyacophila species presented in this paper are recorded for the first time on the area of Kosovo. We also provide new data for the disjunctive distribution of R. palmeni in south-eastern Europe, from Kosovo and Croatia.

During August and September 2018 we collected the macroinvertebrate fauna in the Leqinat Lake, Kosovo. The Leqinat lake (great lake) is a mountain lake found in National Park "Bjeshkët e Nemuna" in western Kosovo, shared between Kosovo and Montenegro. Macrozoobenthos specimens were...

Freshwater ecosystems in Kosovo have undergone significant degradation in recent years due to various anthropogenic pressures, including sewage effluents, industrial discharge, water intakes, and riverbed degradation. Consequently, the populations of freshwater biota, including bioindicators,...

In this paper, we present new faunistic data of the spider fauna from the Sharr Mountains (Kosovo), one of the least investigated areas in the Balkans. Previously only 27 species of spiders were known from the Kosovo part of the Sharr Mountains but with this investigation, the number has increased to 74. Pictures of rare and interesting species are provided. We also include a new record from the North Macedonian part of the Sharr Mountains. In total we report fifty species, eight of which are first records for Sharr Mountains, twenty-eight are first records for Kosovo, and one species is reported for the first time for North Macedonia. Species recorded for the first time from the Sharr Mountains belong to the following genera: Histopona, Clubiona, Zelotes, Ceratinella, Mughiphantes, Robertus and Ozyptila. We also provide a checklist of spider species for the Sharr Mountains in Kosovo.
