Type species. Myrina epirus C. Felder, 1860.

Definition. DNA sequence analysis reveals that several species of Deudorix Hewitson, 1863 (type species Dipsas epijarbas F. Moore, 1858) form a subclade genetically differentiated from others at the subgenus level (Fig. 24 blue and dark blue); e.g., their COI barcodes differ by 5.8% (38 bp), and, therefore, they represent a new subgenus. This new subgenus is differentiated from its relatives by its creamy-white ventral wings with dark brown discal and submarginal bands and margins, a longitudinal stripe in the anal area of the hindwing, and an orange stripe with dark spots (some blue-pupilled) extending from the tornus along the submarginal band, sometimes penetrating it. In DNA, a combination of the following characters is diagnostic in the nuclear genome: cce3391.1.3:A1839G, cce49.4.1:A150T, cce8439.15.1:T595C, cce8439.15.1:T945A, cce 2318.3.4:G270A, cce1567.13.2:T48T (not A), cce303136.3.19:T96T (not C); and COI barcode: T133A, A268G, T391A, T436A, T536C, A538T.

Etymology. The name is formed from [Ara] wacus Kaye, 1904, a Neotropical genus of Lycaenidae with a striped pattern in many species reminiscent of this new subgenus, but with additional stripes (thus a longer name). Furthermore, the name hints at a ventral wing pattern that is odd and eccentric (i.e., "wacky") for Deudorix . The name is a masculine noun in the nominative singular.
