RESUMO

The Miridae (Hemiptera: Heteroptera) is one of the most species rich families of insects, with about 11,000 described species and comprises about 25% of the Heteroptera. It is one of the most important groups of insects due to the great diversity of species, wide distribution, the range of feeding habits and damage caused to crops. The Prepops genus lies in subfamily Mirinae, tribe Resthenini. Contains 197 species distributed only in American continent, from Canada to Argentina and a few species are pests in food crops. In order to contribute with the knowledge of Prepops Reuter, taxonomic and biogeographic studies were done in this thesis. The results were organized into three papers. In the first one, a total of fourteen species of Prepops genus were recorded from Rio Grande do Sul state, Brazil. New records include seven species. Two new species P. cangussuensis and P. turvoensis are described. For each species geographic distribution and diagnosis were presented. And ultimately, a key to Rio Grande do Sul species are provided to assist identification. The second paper brings for 58 Prepops species, all the published references, their geographic distribution, diagnosis, host plants and illustrations of dorsal habitus, male and female genitalia. And in the third paper, a biogeographic analysis was carried out for the first time in Mirinae subfamily. In addition, it was the first attempt to use data from Miridae in a qualitative method to identify areas of endemism. Network analysis recognized 14 natural units of cooccurrence (UCs), embedded in Neartic and Neotropic realms. Some of the UCs recognized agree (totaly or partially) with tradicional areas of endemism, or with biogeographic regionalization proposed by different authors for unlike taxa.
