TAXONOMIC NOTES ON SOME PALAEARCTIC SPECIES OF THE WEEVIL GENUS TYCHIUS WITH THE DESCRIPT ION OF FIVE NEW SPECIES (COLEOPTERA, CURCULIONIDAE)
Five new species belonging to the weevil genus <em>Tychius</em> Germar, 1817 are here described: <em>Tychius</em> <em>magnithorax</em> n. sp. (southern central Turkey, Syria), <em>T. podlussanyi</em> n. sp. (northern Portugal), <em>T. ucrainicus</em> n. sp. (eastern Ukraine), <em>T. weilli</em> n. sp. (Syria), <em>T</em>. <em>zagrosianus</em> n. sp. (south-western Iran). For each taxon a description, habitus photograph, figures of rostrum and genitalia when useful for taxonomy, and differential characters from the closely related species are provided. A neotype is designated for <em>Tychius</em> <em>conspersus</em> Rosenhauer, 1856, and the following synonymy is proposed: <em>T</em>. <em>conspersus</em> Rosenhauer, 1856 = <em>T. antoinei</em> Hustache, 1944 n. syn. Finally the male of <em>T.</em> <em>boroveci</em> Caldara, 1995 and the male genitalia of<em> T. lacteoguttatus</em> Desbrochers, 1875 are described for the first time.
