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. v. (eastern Ukraine), T. weilli n. sp. (Syria), T. zogrosianus 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.
