Acta entomologica slovenica, 14 (1), 2006latipennis Curtis. Vrsta Rhyacophila dorsalis Curtis je izbrisana iz seznama innadomeøœena z alopatriœno vrsto R. nubila Zetterstedt. Ena vrsta (Stenophylaxlatipennis) in ena podvrsta (Stenophylax vibex speluncarum) sta bili umaknjenizaradi napaœne doloœitve in pomanjkanja podatkov. Vrsta Drusus serbicusMarinkoviå je endemiœna v Srbiji, medtem ko so Crunoecia bosniaca Marinkoviå-Gospodnetiå, Rhyacophila bosnica Schmid in Rhyacophila vranitzensis Marinkoviået Botosaneanu endemiœne vrste zahodnega Balkana.KLJUŒNE BESEDE: Trichoptera, favna, Srbija, liœinke, gorske rekeIntroductionCompiling of the list of Trichoptera of Serbia began with faunisticalinvestigations of Radovanoviå (Radovanoviå 1931; 1935; 1953). It was continued byMarinkoviå-Gospodnetiå (Marinkoviå-Gospodnetiå 1975; 1980) and due to theirwork 154 species of Trichoptera were determined in the fauna of Serbia.Having in mind the geographic position of Serbia on the Balkan Peninsula, andthe fact that four faunistical zones of the freshwater fauna of Europe contact eachother on its territory (Botosaneanu and Malicky, 1978), much more than 154 specieswere expected in the territory. In the west, the Dinaric system of mountains and areawest of the Vardar-Morava line belong to zone 5; the south-western part of Serbiawith Øarsko-Pind system belongs into the zone 6 together with Macedonia, Albaniaand Greece; the part of Serbia east of the above mentioned line together withBulgaria is in zone 7, and the area north of the Sava and Danube Rivers, i.e., thePannonian lowland, belongs to the zone 11. The richness of the Trichoptera speciesmay also be expected in the fauna of Serbia due to great habitat diversity. In the northof Serbia there is a vast Pannonian plain, and its still waters are inhabited by a faunasignificantly different from one that inhabits mountainous parts south of the Savaand the Danube. This plain is a natural barrier which separates mountainous parts ofSerbia from the central European mountains preventing direct mixture of theirfaunas. However, the mountains of eastern Serbia are linked to the mountains ofcentral Europe via the mountains of the Dinarides and the Alps, which to a certainextent open routes to migrations of the species between the mountains of centralEurope and the Balkans. Between the Balkan-Carpates arch of mountains in thenorth-eastern part and the Dinarides in the west, there are old Rodopes which stretchfrom the southeast. As a consequence of all abovementioned, certain regions of theBalkans are inhabited by Trichoptera fauna, which has a considerable percentage ofendemic species, many of which occur in a very small area. Also, it has been foundthat many endemic species of the Dinarides are closely related to endemic species ofthe Carpathians and that these species are allopatric (Marinkoviå-Gospodnetiå,1978).Since the publication of the first list of Trichopteran fauna in 1980 (Marinkoviå-Gospodnetiå 1980), research on Trichoptera, primarily larvae, has undergoneintensification in Serbia. This has contributed significantly to our understanding of56
