Oeonus Godman, 1900 , new status, is a subgenus of Oxynthes Godman, 1900

Oeonus Godman, 1900 -XI (type species Oeonus pyste Godman, 1900 ) clusters closely with Oxynthes Godman, 1900 -X (type species Goniloba corusca Herrich-Schäffer, 1869 ) in the genomic tree ( Fig. 4 blue). COI barcode difference between the type species of these two genera is 9.6% (63 bp). Genetic differentiation between Oeonus and Oxynthes is approximately the same as between Orthos orthos and Orthos minka that were formerly considered conspecific ( Fig. 4 magenta and green). Both Oeonus and Oxynthes include a small number of species and are not separated from each other by a prominent break (i.e, longer internal branches) comparable to that separating them both from Testia Grishin, 2019 . Therefore, we propose to treat these species as congeneric and place Oeonus , stat. nov. as a subgenus of Oxynthes .

FIGURE 4. Nuclear genome tree of selected Carystina and Hesperiina. The tree is constructed from protein-coding regions. Statistical support values are shown by nodes. For each specimen, its name adopted in this work is given first, and a previously used name is listed in square brackets (if different), supplemented with the DNA sample number, type status, general locality, year of collection (when known), and, for primary type specimens, their repository. Synonyms are given in parentheses preceded by “=”, and in addition by “‡” for unavailable names. The type status refers to this synonym, if the synonym name is provided. Green vertical bar cuts the tree into genera, except Vertica, which is characterized by lower evolutionary rate (leaves are closer to the root compared to most others). Yellow shading denotes genera and its width (horizontal dimension) is proportional to the genetic differentiation within each genus. Taxa discussed in the text are shown in different colors: Carystus elvira (orange), Orthos minka, stat. nov. (green), Orthos orthos (purple), Orthos hyalinus, stat. rest. (olive), Oxynthes (blue, subgenus Oeonus labeled in dark blue), Lindra neroides, comb. nov. (red, neotype labeled in margenta), Lindra brasus (cyan), and Decinea (gray).
