Comments: The nominal subgenus is the largest of Edessa with 79 species ( Table 1 View TABLE 1 ) that can be separated in several groups of species. Among the species mentioned by Stål (1872) as part of the species group Edessa , only Edessa cervus (Fabricius, 1787) , E. antilope (Fabricius, 1798) , E. taurina Stål, 1872 , E. arabs (Linnaeus, 1758) and E. cylindricornis Stål, 1872 were considered here as part of the subgenus Edessa . Three species groups described to Edessa belong to the nominal subgenus: cervus ( Fernandes & van Doesburg 2000b) , metallica ( Fernandes & Campos 2011) and ovina ( Fernandes & Silva 2021) . The nominal subgenus can be separated from most genera of Edessinae and subgenera of Edessa by the shape and color of the humeral angle. A comprehensive diagnose separating them can be found in Almeida et al. (2018) and Nunes et al. (2020). Four genera— Anisoedessa Nunes & Fernandes, 2019 , Calcatedessa Silva & Fernandes, 2021, Graziaedessa Eger, 2021 , and Mediocampus Thomas, 1994 —were never included in any diagnostic discussion between the genera of Edessinae . The subgenus Edessa can be separated from these four genera by the shape of the humeral angle described above. In all these four genera the humeral angles are dentiform or rounded, slightly developed and flat.

Comments: The species belonging to the E. sexdens group have a large morphological variety, but also groups of very similar species. Despite this, the group has a set of characteristics that are not found in other species of the subgenus Edessa : connexival segments with a pair of dark spots ( Fig. 24 A View FIGURE 24 ); superior process of the genital cup laminar dorsally and continued ventrally by a carina ( Fig. 1 B,E View FIGURE 1 ); and oblique to the parameres ( Fig. 1 B,D,E View FIGURE 1 ); parameres with three lobes ( Fig. 1 D,E View FIGURE 1 ) (Silva 2017). Other characteristics are also related to the group, such as: anterior arms of the metasternal process with excavated apex ( Fig. 1 G View FIGURE 1 ); ventral side of the abdomen raised medially ( Fig. 24 B View FIGURE 24 ); rounded shallow excavation near each spiracle ( Fig. 24 B View FIGURE 24 ); union of dorsal rim with posterolateral angles grooved ( Fig. 2 A,B View FIGURE 2 ). However, within the E. sexdens group there are species that do not have the entire set of characteristics mentioned above. A few species do not have the spots on connexival segments ( Fig. 26 A View FIGURE 26 ); and others do not have the ventral carina of the superior process of the genital cup ( Figs. 4 B,E View FIGURE 4 , 7 B View FIGURE 7 , 8 B View FIGURE 8 ).
