Type species. Dodona ouida Hewitson, 1866 .

Definition. Genome-based phylogeny reveals that Dodona Hewitson, 1861 (type species Melitaea durga Kollar, 1844) splits into four clades that we define as subgenera (Fig. 5). Two of them have names: Dodona, which consists of only the type species, and Balonca F. Moore, 1901 (type species Dodona deodata Hewitson, 1876), which includes all other species not placed in the two new subgenera. The clade with Dodona ouida Hewitson, 1866 (type locality in India: Darjeeling) (Fig. 5 red) is sister to all other Dodona species and represents the first new subgenus. This new subgenus differs from its relatives by the following combination of characters: brown wings with three (not four) continuous orange stripes on the forewing (submarginal, discal, and basal) in males, and a single cream forewing discal band in females; and the ventral hindwing having a black spot by the costa in the middle with a white spot distad merged with it. In DNA, a combination of the following characters is diagnostic in the nuclear genome: cne246.3.1:A1743G, cne792.27.11:G1335C, cne14967.2.1:A330T, cne14967.2.1:T342C, cne14967.2.1: C358A; and in COI barcode: A31T, T59C, A79T, T364C, A469T, 499A (not T).

Etymology. The name of the subgenus is tautonymous with its type species name and is a feminine noun in the nominative singular.

Species included. Only the type species (i.e., Dodona ouida Hewitson, 1866).

Parent taxon. Genus Dodona Hewitson, 1861 .
