Having met the conditions of ICZN Article 75.3, the neotypes of Pachytychius tychioides Desbrochers, 1900 and Tychius scrobiculatus Rosenhauer, 1856 are designated. The lectotypes of Sibinia grandicollis Waltl, 1835 and Tychius sinaiticus Crotch, 1872 are also designated. These taxa are transferred to Pachytychius (comb. n.), whereas P. tychioides Desbrochers, 1900 and T. scrobiculatus Rosenhauer, 1856 are transferred to Tychius and Aubeonymus respectively (comb. n.). The following new synonymies are proposed: Aubeonynmus carinicollis (Lucas, 1849) = Tychitus scrobiculatus Rosenhauer, 1856 syn. n.; Pachytychius hordei grandicollis (Waltl, 1835) stat. n. = Pachytychius hordei .squamosus (Gyllenhal, 1836) syn. n.; Pachytychius sinaiticus (Crotch, 1872) = Pachytychius sobrinus Tournier, 1874 syn. n.; Tychius hierosolymus (Desbrochers, 1901) = Pachytychius tychioides Desbrochers, 1900 (non Pascoe, 1887) syn. n.10aPachytychius obscuricollis1 aCaldara, Roberto  uhttps://weevil.myspecies.info/synonymic-notes-some-pachytychius-description-new-species-coleoptera-curculionidae
