Two new brachypterous species of the genus Scotussa, with restricted distributions, are described for one of the most importantand greatly threatened biodiversity hotspots, the Atlantic Forest. These species belong to the genus group Scotussae, adiverse group regarding mobility and oviposition habits. It has been mentioned that these characteristics could lead to restrictionsin the species distribution. Based on these antecedents and considering the importance of biodiversity conservationwithin the Atlantic Forest, we performed novel conservation indices for this group. The rapid assessment indices calculatedherein are based upon Red List status, endemism, dispersal capacity, and life-history traits that allowed us to identify areasfor conservation for this group of grasshoppers. For a better understanding of the conservation status of the group, theresults of the indices were compared with protected areas and Key Biodiversity Areas. Moreover, historical biome stabilitywas also considered since it has been associated with different distributional and diversification patterns within the genusgroup Scotussae. The approach applied indicates that the indices recovered different but complementary information. TheGrasshopper Biotic Index (GBI) determined important regions for conservation within the richest region of the group whilethe GBI/SiteScore located regions with lower diversity values for the group but with high importance regarding endemisms.ClinicalTrials.gov Identifier: LSID urn:lsid:zoobank.org:pub:10C911D0-D8A6-4AC8-A2FD-3AD51407973F
