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. This new subgenus differs from its relatives by the following combination of characters (see Hall and 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 .
