Type species. Ocybadistes hypomeloma View in CoL Lower, 1911.

Definition. Genomic phylogeny of the tribe Taractrocerini Voss, 1952 reveals that Potanthus hypomeloma (Lower, 1911), comb. nov. cannot be reliably assigned to existing subgenera in Potanthus Scudder, 1872 View in CoL (type species Hesperia omaha Edwards, 1863 View in CoL ) (see above) and thus represents a new subgenus. This new subgenus keys to L. 2.3 in Evans (1949) and differs from its relatives by a combination of the following characters: flattened antennal club; notched at the tip uncus not narrowing to a single point; rounded valva with a terminal small knob; narrow and irregular black discal forewing stigma in males between the veins M 3 and 1A+2A; whitish inner margin of ventral hindwing; and orangeyellow spot in the cell RS-M 1 of the dorsal hindwing separated from the postdiscal band ( Fig. 45a). In DNA, a combination of the following characters is diagnostic in the nuclear genome: aly956.3.2: T502 C, aly956.3.2:G2082A, aly 1264.8.3:G292C, aly4305.13.5:G141A, aly517.17.2:G534A, and COI barcode: T13 C, T52 C, T256 C, T358 C, A484T.

Etymology. This name combines the previous and current genus names of these species: Ocy [badistes] + [Pota] nthus and is a masculine noun in the nominative singular.

Species included. Only the type species (i.e., Ocybadistes hypomeloma Lower, 1911).

Parent taxon. Genus Potanthus Scudder, 1872 .

and not Arrhenes Mabille, 1904

Genomic phylogeny of the tribe Taractrocerini Voss, 1952 that includes a pair of Padraona tranquilla Swinhoe, 1905 (type locality in Papua New Guinea: Milne Bay, a male shown in Fig. 45b), currently in the genus Arrhenes Mabille, 1904 (type species Pamphila marnas Felder, 1860 ) reveals that it is not monophyletic with this genus and instead originates within Kobrona Evans, 1935 (type species Plastingia kobros Plötz, 1885 ). Therefore, Padraona tranquilla Swinhoe, 1905 belongs to the genus Kobrona Evans, 1935 and not Arrhenes Mabille, 1904 , and we propose Kobrona tranquilla (Swinhoe, 1905) , comb. nov.
