TAXONOMIC NOTES ON SOME PALAEARCTIC SPECIES OF THE WEEVIL GENUS TYCHIUS WITH THE DESCRIPT ION OF FIVE NEW SPECIES (COLEOPTERA, CURCULIONIDAE)

Abstract

Five new species belonging to the weevil genus Tychius Germar, 1817 are here described: Tychius magnithorax n. sp. (southern central Turkey, Syria), T. podlussanyi n. sp. (northern Portugal), T. ucrainicus n. sp. (eastern Ukraine), T. weilli n. sp. (Syria), T. zagrosianus 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 Tychius conspersus Rosenhauer, 1856, and the following synonymy is proposed: T. conspersus Rosenhauer, 1856 = T. antoinei Hustache, 1944 n. syn. Finally the male of T. boroveci Caldara, 1995 and the male genitalia of T. lacteoguttatus Desbrochers, 1875 are described for the first time.
