On the Trichoptera of the Balkan: survey on species complexes of Polycentropus ierapetra, Rhyacophila balcanica, R. bosnica and Notidobia nekibe

The Balkan mountain ranges represent the most diverse hot spots of the European biodiversity still very far from being completely explored. Besides new faunistic data here we have described Drusus gornistok Oláh, sp. nov. in the D. discophorus species complex, surveyed four species complexes and described Polycentropus maglic Oláh, sp. nov. , P. staraplanina Oláh, sp. nov. in the Polycentropus ierapetra new species complex; Rhyacophila albanica Oláh & Ibrahimi sp. nov., R. montenegra Oláh, sp. nov. , R. syrikaltera Oláh & Ibrahimi sp. nov. in the Rhyacophila balcanica new species complex; R. kozara Oláh, sp. nov. , R. sarplana Oláh, sp. nov. , R. staraplana Oláh, sp. nov. in the Rhyacophila bosnica new species complex; Notidobia kerkina Oláh, sp. nov. , N. koraba Oláh, sp. nov. , N. lakmosa Oláh, sp. nov. , N. vaillanti Oláh, Vinçon & Ibrahimi sp. nov. in the Notidobia nekibe new species complex. The subspecies status of the following taxa were raised to species rank: Polycentropus adana Sipahiler, 1996 stat. nov., P. anatolica Sipahiler, 1989 stat. nov., P. dirfis Malicky, 1974 stat. nov., P. ikaria Malicky, 1974 stat. nov., P. isparta Sipahiler, 1996 stat. nov., P. kalliope Malicky, 1976 stat. nov., P. septentrionalis Kumanski, 1986, stat. nov., P. slovenicus Malicky, 1998 stat. nov.
