Miscellaneous notes on the systematics of and synonymy in Entiminae (Coleoptera, Curculionidae)

This work addresses a collection of miscellaneous notes intended to resolve several issues in synonymy and taxonomy of the Entiminae tribes Byrsopagini, Cyphicerini, Mesostyloidini, Phyllobiini and Polydrusini. New synonyms are herein proposed: Peronaspis Suvorov, 1915 = Viridistylus Colonnelli & Paladini, 2019, syn. nov. ; Peronaspis claviger (Faust, 1894) = Viridistylus robustus Colonnelli & Paladini, 2019, syn. nov. ; Titinia tenuis (Germar, 1848) = Myllocerus bacchus Voss, 1949, syn. nov. ; Brachymerinthus Faust, 1886 = Parakasakhstania Magnano, 2009, syn. nov. ; Brachyxystus subsignatus subsignatus Faust, 1897 = Polydrusus setifrons kashmirensis Voss, 1959, syn. nov. ; Polydrusus rufulus Hochhuth, 1847 = Polydrusus reitteri Kirsch, 1878, reestablished synonymy, = Polydrusus freyi Zumpt, 1933, syn. nov. ; Polydrusus viridimaculatus Pic, 1919, stat. nov. = Polydrusus scapularis Pesarini, 1975, syn. nov. New taxonomic status is proposed for Polydrusus viridimaculatus Pic, 1919, stat. nov. , which is promoted to species from the subspecies of Polydrusus picus (Fabricius, 1792). New combinations. Brachymerinthus densesquamosus (Magnano, 2009), comb. nov. from Parakasakhstania ; Phyllobius (Phyllobius) constellatus (Voss, 1959), comb. nov. and Brachyxystus subsignatus praevius (Voss, 1959), comb. nov. from Polydrusus Germar, 1817. New tribal placements: Sepiomus Aurivillius, 1891 and Cylindromus Aurivillius, 1891 are transferred from Byrsopagini back to Cyphicerini (subtribe Cyphicerina); Brachymerinthus Faust, 1886, is transferred from Phyllobiini to Mesostyloidini, and Brachyxystus Faust, 1897, from Phyllobiini to Polydrusini. The lectotype of Polydrusus picus var. viridimaculatus Pic, 1919 is designated. The type locality of Myllocerus bacchus is Bacchus Marsh, a town near Melbourne in Victoria State, Australia, not Lake Victoria in Africa. Polydrusus rufulus Hochhuth, 1847 is recorded in Iran for the first time.
