ON SEVEN OVERLOOKED CURCULIONOIDEA FROM NORTHERN ITALY (Coleoptera)

Seven Curculionoidea described from Lombardy (northern Italy) by Virginio Betta in 1857 and overlooked by subsequent authors are here treated. Since the Betta collection where their types are supposed to have been preserved was never traced, neotypes of all of them are designated with the purpose of clarifying their taxonomic status. Revised combinations are: Pseudeuparius pictus (Betta, 1857) comb. rev. from Tropideres Schoenherr, 1823; Pachytychius aericollis (Betta, 1857) comb. rev. from Smicronyx Schoenherr, 1843; Mecinus vittatus (Betta, 1857) comb. rev. from Gymnetron Schoenherr, 1825; Mecinus areolatus (Betta, 1857) comb. rev. from Gymnetron Schoenherr; Mecinus flavipes (Betta, 1857) comb. rev. from Gymnetron Schoenherr. The following new synonymies are established: Pseudeuparius centromaculatus (Gyllenhal, 1833) [= P. pictus (Betta, 1857) syn. n.]; Pachytychius sparsutus (Olivier, 1807) [= P. aericollis (Betta, 1857) syn. n.]; Smicronyx coecus (Reich, 1797) [= S. minusculus (Betta, 1857) syn. n.]; Mecinus labilis (Herbst, 1795) [= M. vittatus (Betta, 1857) syn. n.]; Mecinus pascuorum (Gyllenhal, 1813) [= M areolatus (Betta, 1857) syn. n.]; Mecinus latiusculus (Jacquelin du Val, 1855) [= M. flavipes (Betta, 1857) syn. n.]; Mecinus circulatus (Marsham, 1802) [= M. sericatus Betta, 1857 syn. n.].Original Abstract: Sono qui trattate sette specie di curculionoidei descritti di Lombardia da Virginio Betta nel 1857 e ignorati dagli autori successivi. Poiche una collezione Betta dove presumibilmente erano conservati i loro tipi non esiste piu, sono designati i loro neotipi allo scopo di fissare il loro status tassonomico. Combinazioni nuove sono: Pseudeuparius pictus (Betta, 1857) comb. rev. da Tropideres Schoenherr, 1823; Pachytychius aericollis (Betta, 1857) comb. rev. da Smicronyx Schoenherr, 1843; Mecinus vittatus (Betta, 1857) comb, rev. da Gymnetron Schoenherr, 1825; Mecinus areolatus (Betta, 1857) comb. rev. da Gymnetron Schoenherr; Mecinus flavipes (Betta, 1857) comb. rev. da Gymnetron Schoenherr. Vengono poi stabilite le seguenti nuove sinonimie: Pseudeuparius centromaculatus (Gyllenhal, 1833) [= P. pictus (Betta, 1857) syn. n.]; Pachytychius sparsutus (Olivier, 1807) [= P. aericollis (Betta, 1857) syn. n.]; Smicronyx coecus (Reich, 1797) [= S. minusculus (Betta, 1857) syn. n.]; Mecinus labilis (Herbst, 1795) [= M. vittatus (Betta, 1857) syn. n.]; Mecinus pascuorum (Gyllenhal, 1813) [= M areolatus (Betta, 1857) syn. n.]; Mecinus latiusculus (Jacqu
