Keys to Metaphotina species

1. Males’s vertex convex ( Fig. 19A View FIGURE 19 ). Ventral phallomere left margin curving smoothly towards the spiniform projection of the sdp ( Fig. 20A View FIGURE 20 ). Left phallomere’s posterior bending convex ( Fig. 20A View FIGURE 20 ). Females’ CG8 proximal projections angular, with sharp edges ( Fig. 21A View FIGURE 21 ). cxdl strongly sclerotized ( Figs. 21A, D View FIGURE 21 ). Distributed mainly in the Brazilian Cerrado biome and neighboring semiarid habitats within N. Argentina, S. Bolivia, Paraguay, and Uruguay ( Figs. 24 View FIGURE 24 , 26 View FIGURE 26 )................................................................................................ Metaphotina bimaculata ( Saussure, 1870)

- Male vertex flattened ( Figs. 20B, C View FIGURE 20 ). Ventral phallomere left margin curving sharply towards the spiniform projection of the sdp ( Figs. 21B, C View FIGURE 21 ). Females’ CG8 proximal projections rounded ( Figs. 21B, 21C View FIGURE 21 ). cxdl membranous ( Figs. 21E, F View FIGURE 21 ). Distributed only in the Caatinga biome and adjacent areas ( Figs. 25 View FIGURE 25 , 26 View FIGURE 26 )................................................... 2

2. Male vertex with a narrow, longitudinal depression bisecting its top. ( Fig. 19B View FIGURE 19 ). Mesothoracic wings with a brown spot of variable size on the central portion of the discoidal field, metathoracic wings hyaline ( Fig. 22C View FIGURE 22 ). Females’ vertex with strong bump medially and with deep excavated ps ( Fig. 19E View FIGURE 19 ). Metathoracic wings with longitudinal veins of anal area alternating black and white ( Fig. 22D View FIGURE 22 ). CG8 hexagonal, proximal projections as small spines, sbu acute ( Fig. 21E View FIGURE 21 ). Distributed in the northernmost regions of the Caatinga of northeastern Brazil ( Figs. 25 View FIGURE 25 , 26 View FIGURE 26 ).................................................................................................. Metaphotina austri Ferraz, Souza-Dias & Rivera, 2023
