Two new brachypterous species of the genus Scotussa, with restricted distributions, are described for one of the most important and greatly threatened biodiversity hotspots, the Atlantic Forest. These species belong to the genus group Scotussae, a diverse group regarding mobility and oviposition habits. It has been mentioned that these characteristics could lead to restrictions in the species distribution. Based on these antecedents and considering the importance of biodiversity conservation within the Atlantic Forest, we performed novel conservation indices for this group. The rapid assessment indices calculated herein are based upon Red List status, endemism, dispersal capacity, and life-history traits that allowed us to identify areas for conservation for this group of grasshoppers. For a better understanding of the conservation status of the group, the results of the indices were compared with protected areas and Key Biodiversity Areas. Moreover, historical biome stability was also considered since it has been associated with different distributional and diversification patterns within the genus group Scotussae. The approach applied indicates that the indices recovered different but complementary information. The Grasshopper Biotic Index (GBI) determined important regions for conservation within the richest region of the group while the GBI/SiteScore located regions with lower diversity values for the group but with high importance regarding endemisms.
描述了两种分布范围有限的新的短翅性斯科图萨属物种，这是最重要和受到极大威胁的生物多样性热点之一——大西洋森林。这些物种属于斯科图萨属组，这是一个在移动性和产卵习惯方面具有多样性的群体。有人提到，这些特征可能会限制物种的分布。基于这些背景，并且考虑到大西洋森林内生物多样性保护的重要性，我们为该组进行了新的保护指数评估。此处计算的快速评估指数基于红色名录状况、特有性、扩散能力和生活史特征，使我们能够确定该组蝗虫的保护区域。为了更好地了解该组的保护状况，将指数结果与保护区和生物多样性关键区域进行了比较。此外，还考虑了历史生物群落稳定性，因为它与斯科图萨属组内不同的分布和多样化模式有关。应用的方法表明，指数回收了不同但互补的信息。蝗虫生物指数（GBI）确定了该组最丰富地区内的重要保护区域，而 GBI/地点得分则确定了该组多样性值较低但特有性重要性较高的区域。
