The status of formerly synonymized species, Rhyacophila ferruginea (Scopoli 1763) and Rhyacophila septentrionis McLachlan 1865 was also assessed. The type of R.

sp. n. (Trichoptera: Limnephilidae), a new species from Bjeshkët e Nemuna National Park in the Republic of Kosovo, with molecular and ecological notes.

Background: The Western Balkans are an important hotspot of caddisfly diversity in Europe, with several microscale endemics, many of which were discovered during the recent years. The genus Wallengren, 1891 likely originated and diversified in Europe, with the Balkan Peninsula being one of the most important diversity hotspots.

New Information: In this paper, we describe the new species sp.

Distribution of two rare taxa of caddisflies (Trichoptera: Rhyacophilidae, Polycentropodidae) from the Republic of Kosovo.

Background: The knowledge about distribution, ecology and species composition of caddisflies of the Balkan Peninsula is still not complete. The ongoing investigations of the last years highlight this area as an important hotspot of caddisfly diversity. has been considered a narrow range endemic of Slovenia and surrounding areas.

The larva of Rhyacophila palmeni McLachlan 1879 (Trichoptera: Rhyacophilidae) from Greece and Kosovo with notes on ecology and zoogeography including a key to the known Greek Rhyacophila larvae.

The larva of Rhyacophila palmeni McLachlan 1879 is described, based on material from Greece and Kosovo. The diagnostic features of the species are discussed and illustrated, and some information on its ecology and distribution are included. In addition, diagnostic characters for larvae of the known Greek Rhyacophila species are provided.

Drusus sharrensis sp. n. (Trichoptera, Limnephilidae), a new species from Sharr National Park in Kosovo, with molecular and ecological notes.

New records for the Kosovo caddisfly fauna with the description of a new species, Drusus dardanicus sp. nov. (Trichoptera: Limnephilidae).

The Balkan Peninsula is one of the most important European hotspots of freshwater biodiversity. The region is, however, to a large extent insufficiently investigated. Here we present data on distribution of caddisflies in one particularly understudied area, the Republic of Kosovo.

Larval morphology and phylogenetic position of , , and (Trichoptera: Limnephilidae: Drusinae).

In a recent 3-gene phylogeny of the Trichoptera subfamily Drusinae Banks, 1916 molecular data clearly correlated with the morphology and feeding ecology of larvae. The largest of three main groups, the Drusinae grazer clade, exhibits an unusual larval feeding ecology for Limnephilidae, and is the most diverse group. In this paper we describe four previously unknown Drusinae larvae from this clade: Kumanski, 1973 (micro-endemic to Eastern Balkans); Kumanski, 1968 (Dinaric Western Balkans, Hellenic and Eastern Balkan, Asia Minor), Marinković-Gospodnetić, 1971a (micro-endemic to Dinaric Western Balkans); and (Klapálek, 1898) (Carpathians, Dinaric Eastern Balkans).

Three new country records from the genus Limnephilus Leach, 1815 (Trichoptera: Limnephilidae) from the Republic of Kosovo.

New faunistic data on Trichoptera from Kosovo based on sampling carried out during the autumn of 2013 and first half of 2014 are presented. Limnephilusbipunctatus was found in a small stream in Kaqandoll village located in northern Kosovo and in Shtuticë village located in central Kosovo. Two male specimens of Limnephilusdecipiens  were found at Gurrat e Hasan Agës Springs and Bistrica e Lloqanit River, an alpine area in the Lloqan mountains, which belong to the Bjeshkët e Nemuna mountains.

Trichoptera biodiversity of the Aegean and Adriatic sea basins in the republic of Kosovo.

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.

Microscale vicariance and diversification of Western Balkan caddisflies linked to karstification.

The karst areas in the Dinaric region of the Western Balkan Peninsula are a hotspot of freshwater biodiversity. Many investigators have examined diversification of the subterranean freshwater fauna in these karst systems. However, diversification of surface-water fauna remains largely unexplored.

The caddisfly fauna (Insecta, Trichoptera) of the rivers of the Black Sea basin in Kosovo with distributional data for some rare species.

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 paper are first records for the Kosovo caddisfly fauna. The unexpected discovery of several species during this investigation: Agapetus delicatulus McLachlan, 1884, Psychomyia klapaleki Malicky, 1995, Tinodes janssensi Jacquemart, 1957, Hydropsyche emarginata Navas, 1923, Drusus botosaneanui Kumanski, 1968, Potamophylax rotundipennis (Brauer, 1857), Potamophylax schmidi Marinković-Gospodnetić, 1970, Ceraclea albimacula (Rambur, 1842), Helicopsyche bacescui Orghidan & Botosaneanu, 1953, Adicella filicornis (Pictet, 1834), Beraea maurus (Curtis, 1834) and Beraeamyia hrabei Mayer, 1937 illustrates that collections from poorly investigated areas in Europe will almost certainly revise the existing knowledge on the distribution of these and other species.
