Oarisma (Copaeodes) favor ( Evans, 1955) , new status

Genomic sequencing of Copaeodes jean jean Evans, 1955 (type locality in Guyana) ( Fig. 9 green) and Copaeodes jean favor Evans, 1955 (type locality in Brazil: Paraná) ( Fig. 9 magenta), both currently in the genus Oarisma Scudder, 1872 (type species Hesperia powesheik Parker, 1870 ), reveals prominent genetic differentiation between them, e.g., their COI barcodes differ by 4.7% (31 bp). Combined with phenotypic differences mentioned by Evans (1955), like the presence of dark border on wings and the extent of whitening between veins on ventral hindwing, these differences suggest a species status for Oarisma (Copaeodes) favor ( Evans, 1955) , stat. nov.

Figures

FIGURE 9. Genomic trees of Oarisma and an outgroup. The trees are constructed from protein-coding regions in a. nuclear genome, b. Z chromosome, and c. mitochondrial genome. Specimens are arranged in the same order in all trees and complete labels are given in panel a only. See Fig. 3 for other notations. Species discussed in the text are labeled in different colors: Oarisma (Oarisma) castanea (red), Oarisma (Copaeodes) jean (green), Oarisma (Copaeodes) favor, comb. nov. (magenta), and outgroups (Thymelicus) are gray. Statistical support values critical for the placement of O. castanea are highlighted in yellow.
