Based on light-trap collections from 1981 to 1993 at Mata do Paraíso (20°46 -20°48 S; 45°50 -45°52 W), a tropical forest environment at Viçosa county, Minas Gerais State, Brazil, a total of 10,809 specimens of leafhoppers (Homoptera: Cicadellidae) were counted, belonging to 11 subfamilies: Agalliinae, Cicadellinae, Coelidiinae, Deltocephalinae, Gyponinae, Iassinae, Idiocerinae, Neocoelidiinae, Nirvaninae, Typhlocybinae and Xestocephalinae. Genera and species of Typhlocybinae were not identified. In this work are listed 62 determined genera and 156 species. Among the species 37 of them new to science and 10 are recorded for the first time to Brazil. It was also found 49 new records from Minas Gerais and 58 from Viçosa. Illustrated taxonomic keys for identification of subfamilies, tribes and genera are presented. Within and between-year fluctuations in abundance and richness of the leafhoppers were analyzed. Annual fluctuations in the population were related to local temperature and rainfall patterns. Wet season faunal structure was different from that of the dry season at Mata do Paraíso. Among the more representative species Xestocephalus desertorum (Berg, 1879), X. ancorifer Linnavuori, 1959 (Xestocephalinae), Planicephalus flavicosta (Stal, 1860), Graminella striatella Linnavuori, 1959, Balclutha sp. 1 (Deltocephalinae), Plesiommata corniculata Young, 1977 and Hortensia similis (Walker, 1951) (Cicadellinae) were significantly more abundant during the wet seasons; Curtara atomaria (Stal, 1862) (Gyponinae) and Balclutha hebe (Kirkaldy, 1906) showed no difference between wet and dry seasons.
