Type species. Apodemia ochracea Mengel, 1902 .

Definition. Nuclear genome phylogeny reveals that Apodemia ochracea Mengel, 1902 (type locality in Paraguay), currently in the genus Lemonias Hübner, [1807] (type species Lemonias zygia Hübner, 1807 ), is not monophyletic with it and instead is sister to Aricoris Westwood, 1851 (type species Aricoris tisiphone Westwood, 1851 , which is a junior subjective synonym of Erycina tutana Godart, [1824] ), being genetically differentiated from it at the subgenus level ( Fig. 23 purple and labeled orange); e.g., their COI barcodes differ by 9% (59 bp). Therefore, we transfer Apodemia ochracea and phenotypically similar to it Riodina? theodora Godman, 1903 , and Riodina? albofasciata Godman, 1903 from Lemonias to Aricoris forming Aricoris ochracea (Mengel, 1902) , comb. nov., Aricoris theodora (Godman, 1903) , comb. nov., and Aricoris albofasciata (Godman, 1903) , comb. nov. Because the lineage with Aricoris ochracea does not contain type species of any available genus group names, it represents a new subgenus. Harvey (2001) for illustrations and discussion): long falces, not shorter than the tegumen with the uncus; a uniformly broad uncus, not narrowing terminally in dorsal view and with a concave distal margin; a single spike-shaped cornutus in the vesica; the eights abdomen sternite in males is approximately rectangular, not narrowing terminally; the ductus bursae is compressed laterally towards the ostium bursae; the forewing costal margin in males is rather straight to slightly concave in the middle, and the outer margin is concave near the tornus; and wings are dark brown with orange and white bands, patches, and spots (one white spot is in the forewing discal cell). In DNA, a combination of the following characters is diagnostic in the nuclear genome: cne 1364.1.2:A279G, cne 1364.1.2:G296A, cne13787.2.1:T70C, cne13787. 2.1:A84G, cne 2068.2.1:A4182G; and in COI barcode: A73G, 139C, T304C, T532A, A541T.

Etymology. This Aricoris is somewhat similar in wing patterns to some species of Chlosyne Butler, 1870 ( Nymphalidae ): Ari [coris] + Chlosyne . The name is a feminine noun in the nominative singular.

Species included. The type species (i.e., Apodemia ochracea Mengel, 1902 ), Riodina? albofasciata Godman, 1903 , and Riodina? theodora Godman, 1903 .

Parent taxon. Genus Aricoris Westwood, 1851 .
