Freeman, 1969) , Oligoria lucifer (Hübner, [1831]) , and Oligoria mustea (H. Freeman, 1979) , new combinations Previously placed in the genus Decinea Evans, 1955 (type species Hesperia decinea Hewitson, 1876), Cobalus percosius Godman, 1900 is not monophyletic with Decinea type species, which is in the same clade with Buzyges Godman, 1900. Instead, percosius is a very close sister of the monotypic genus Oligoria Scudder, 1872 (type species Hesperia maculata W. H. Edwards, 1865) ( Fig. 16 ), which is in the same clade with Xeniades Godman, 1900. COI barcode difference between maculata and percosius is only 4%. Therefore, we establish a new combination: Oligoria percosius . Due to morphological and genetic DNA similarities, we additionally propose the following new combinations: Oligoria rindgei (H. Freeman, 1969), Oligoria lucifer (Hübner, [1831]), and Oligoria mustea (H. Freeman, 1979) ( Fig. 16 ). All these species were previously placed in Decinea .
