Abstract

The males of the Hydropsyche pellucidula species group found in Turkey are studied. Eight new species are described and illustrated: Hydropsyche boyabat sp. n., Hydropsyche harsitica sp. n., Hydropsyche cerkesica sp. n., and Hydropsyche trabzonica sp. n. from northern Turkey; Hydropsyche belisirma sp. n. and Hydropsyche konya sp. n. from central Turkey; Hydropsyche patara sp. n. from southern Turkey; and Hydropsyche savur sp. n. from southern and southeastern Turkey. The previously recorded species H. pellucidula Curtis, 1834 is not found. The known species Hydropsyche botosaneanui Marinkovic, 1966, Hydropsyche alarensis Sipahiler, 2004, Hydropsyche alanya Sipahiler, 1987 and Hydropsyche incognita Pitsch, 1993 are also described and figured. Diagnostic characters for the separation of the species are given as well as distributional data.
