‾ Femora wholly black, at most a faint reddish stripe dorsally on hind femora...................................... 5
2. Scutellar disc white setose; hind femora with at most 10–12 anteroventral macrosetae, arranged in a single row.......... 3
‾ Scutellar disc black setose; hind femora with 14–15 anteroventral macrosetae, somewhat arranged in a double row................................................................................................. R. strigarius
3. Katatergal macrosetae black, although some yellowish ones may be present; femora red, black ventrally; tomentum golden cinereous; epandrium broad in lateral view, its apex blunt..................................................... 4
‾ Katatergal macrosetae pale yellowish; femora mainly brown although the base is reddish brown; tomentum predominantly cinereous, almost silvery; epandrium thin in lateral view, its apex pointing downwards ( Fig. 12B View FIGURE 12 )........ R. illapa View in CoL sp. nov.
4. Thorax red, except pronotum and some anterior area of pleura, dark brown; male terminalia reddish; phallus strongly flattened laterally (i.e. wide in lateral view) ( Fig. 16D View FIGURE 16 ).................................................. R. supay View in CoL sp. nov.
‾ Thorax and male terminalia brown; phallus narrow ( Fig. 19D View FIGURE 19 )................................. R. uscovilca View in CoL sp. nov.
5. Ocellar triangle with long macrosetae, although no longer than length of escape and pedicel together; epandrium straight, al- though the apex may have a pointing-down projection; phallus narrow, ejaculatory apodeme short to large.............. 6
‾ Ocellar triangle with quite long macrosetae, about 1.5 times the length of scape and pedicel together. Epandrium apex distinctly angled downwards; phallus strongly flattened laterally, ejaculatory apodeme medium sized.......................... 8
6. Mystacal macrosetae black on the upper face and yellowish bellow; katatergite yellowish setose; epandrium apex blunt; ejaculatory apodeme medium sized to short.................................................................... 7
‾ Mystacal macrosetae wholly black, katatergite as well; epandrium apex with a pointing-down projection ( Fig. 10B View FIGURE 10 ); ejaculatory apodeme large ( Fig. 10D View FIGURE 10 )............................................................ R. huiracocha View in CoL sp. nov.
7. Scutellar disc black setose; macrosetae on antepronotum pale to yellowish; abdomen cinereous tomentose, eighth sternite in males with black macrosetae, phallus quite narrow, ejaculatory apodeme medium sized ( Fig. 6D View FIGURE 6 )......... R. apu View in CoL sp. nov.
‾ Scutellar disc yellowish setose; macrosetae on antepronotum black; abdomen golden tomentose, eighth sternite in males with yellowish macrosetae; phallus narrow and ejaculatory apodeme short ( Fig. 14D View FIGURE 14 ) ......................... R. inti View in CoL sp. nov.
8. One pair of apical scutellar macrosetae; microtrichia in m1 barely present, thus, at first glance the apical third of the wing appears to be not fully darkened; epandrium apex strongly angled, almost at 90° ( Fig. 8B View FIGURE 8 )............ R. chicamac View in CoL sp. nov.
‾ 2 – 3 pairs of apical scutellar macrosetae; apical third of the wing fully darkened, microtrichia also abundant on sides of basal fourth of R 4+5, r–m, and m–cu (i.e. wing seems to have three central dark spots); epandrium apex broad, distinctly angled downwards, though less than 90° ( Fig. 4B View FIGURE 4 )...................................................... R. aiapaec View in CoL sp. nov.
