The Mata do Paraiso , an Atlantic Forest reserve, is located at the coordinates 20°48 07 S e 42°51 31 W, in the municipal district of Viçosa, Minas Gerais, Brazil. The objectives of this work were to inventory Cerambycidae species, to elaborate illustrated keys for subfamilies, tribes and species and to determine the influence of the climatic factors on longhorned beetles seasonality of the Mata do Paraiso . In the sampling light trap, beating, entomological net, hand-picking and bait traps were used. To study diversity all species collected with all techniques were considered. To study the influence of the climatic factors only the sampled species with light trap since October of 1986 to March of 2007 were analyzed. A total of 440 long-horned beetles, represented by 140 species, 107 genera, 36 tribes and five subfamilies were collected. The values of species and tribes richness were high compared with other inventories. Twelve species were new records for Minas Gerais State. This information contributes to extend the distribution of these species and also determines a possible relation of them with the Mata Atlântica vegetation. Fourteen species were identified only to genera level and two to tribe level; these species are probably new for the science. Twenty nine keys were elaborated facilitating the identification of the individuals to species level. The temperature and the precipitation influenced positively the richness and abundance of long-horned beetles of the Mata do Paraiso . Cerambycidae diversity decreases in the dry season and increases in the rainy season. This work constitutes a basic guide to identify the longhorned beetles of the Mata do Paraiso and similar ecosystems.
