Corra xanthus (O. Mielke, 1989) , new combination

Vidius xanthus Mielke, 1989 ( type locality in Brazil: S„o Paulo) ( Fig. 7 purple) is not monophyletic with Vidius Evans, 1955 ( type species Narga vidius Mabille, 1891 ) ( Fig. 7 blue), where it is currently placed, and instead is sister to Hesperia coryna Hewitson, 1866 , type species of Corra Grishin, 2019 ( Fig. 7 cyan). Their COI barcodes are 7% (46 bp) different, which is typical for congeners. Therefore, we propose to transfer V. xanthus to Corra , forming Corra xanthus (O. Mielke, 1989) , comb. nov. As a result, Corra is no longer monotypic and we find another example of closely related species with drastically different (for Hesperiidae ) color patterns. Nevertheless, the three brown rays on the ventral hindwing of C. coryna can be traced to three more diffuse elements of C. xanthus hindwing pattern.

FIGURE 7. Nuclear genome tree of selected Moncina: Lerema relatives. See Fig. 4 for notations. Some genera are labeled at their clades. Taxa discussed in the text are shown in different colors: Rectava (red, with Rectava cascatona, comb. nov. labeled in magenta), Lurida (lime, with Lurida zama, comb. nov. labeled in orange), Corra (cyan, with Corra xanthus, comb. nov. and former subspecies of Corra coryna labeled in purple and darker cyan, respectively), Vidius (blue, with species transferred from Cobalopsis labeled in dark blue), Cymaenes (green, with species transferred from Vidius or Nastra and Cymaenes macintyrei, stat. rest. labeled in olive and lilac), and Vehilius (gray, with species transferred from Vidius, Nastra, or Cymaenes labeled in pink). Green arrows point from the clade of the genus where a species was previous placed to the clade of the species that is being transferred between genera.
