Abstract

Abstract: Discothyrea is a genus composed of specialist predatory species rarely recorded and with little known biology. Specimen collection is usually associated with preserved native vegetation. In this work, we explore the landscape of sites with occurrence of Discothyrea seeking to improve knowledge about the natural history of this genus. Species of Discothyrea were recorded in ten Atlantic Forest sites. We analyzed the landscape around the place of occurrence of each species using a 500-m buffer. We classified the landscape as heterogeneous and homogeneous according to the percentage of natural (native vegetation), urban, and rural areas. We found 67 specimens of Discothyrea; 59 of them were D. sexarticulata, occurring in 88% of the fragments. There were also eight specimens of D. neotropica occurring in 12% of the fragments. The results show that D. sexarticulata can be found in homogeneous landscapes with anthropic influence (0-51% of rural area and 0-68% of urban area). Discothyrea neotropica is found in heterogeneous landscapes with a dominant presence of native vegetation (between 74-95%). The results improve knowledge on the biology of Discothyrea mainly in relation to the vicinity of occurrence sites. In addition, the results indicate that regional studies are important to understand species ecology. (AU)
