Social Wasps (Hymenoptera: Vespidae: Polistinae) from Northeastern Brazil: State of the Art

For many years, research about social wasps in the Northeast was neglected due to its climatic and vegetative characteristics, insufficient incentive for training researchers to study these animals and perpetuation of low diversity of these groups in arid environments proposed by Ducke. This study carried out a bibliographic survey of research about social wasps in a 40 years period from January/1979 to December/2019, to determine the overall reality of biodiversity and richness knowledge for social wasps species. One hundred and twenty-four (124) social wasp species have been registered in the Northeast Region, distributed among 20 genera. Epiponini stands out with 84 species, followed by Mischocyttarini (24) and Polistini (16). Sergipe is the only state with no studies and records of species thus far. Such results show the importance of continuing taxonomic studies of these insects to expand their geographic distribution and to determine areas for environmental preservation in the Northeastern biomes, i.e., the Caatinga sensu lato, Cerrado and Amazon rainforest and their transition zones, as they have been insufficiently studied and present high potential for new discoveries. We suggest Alagoas, Ceará, Pernambuco and, especially Sergipe as priority areas since there is a lacking data in these states. Finally, we recommend continuing research on species reports in states like Bahia, using the map created herein to choose future study areas
