Because the Caatinga presents different landscapes, it is important to survey the coleopterofauna in the different phytophysiognomies, seeking to encompass a spatial variability found in this xeric region. Therefore, the objective of this study was to perform a survey of beetles in the semiarid region of Paraíba state, Northeast Brazil. We collected weekly during four years (2009-2013) using Malaise traps in two phytophysiognomies, an area with xerophytic vegetation and another with riparian forest. A total of 6,567 individuals belonging to 383 species and 42 families of Coleoptera were sampled. Chrysomelidae (78 spp.), Curculionidae (57 spp.), and Cerambycidae (28 spp.) had a higher richness, while Chrysomelidae (30.4% of individuals), Curculionidae (8.3%), and Tenebrionidae (7.7%) were the most abundant. A large number of singletons and doubletons were collected despite the long sampling period, indicating that there must be much more species to be recorded. Our results demonstrate a rich fauna of beetles in the studied region. We provide a list of occurring beetles with new records of species for the Paraíba state and thus contribute to the knowledge of the diversity of the Coleoptera in the Northeast Brazil.</p><p></p>
