Definition and diagnosis. Phylogenetic trees reveal that a specimen from Panama identified as Rectava sobrinus Schaus, 1902 (type locality Brazil: Rio de Janeiro) shows prominent genetic differentiation from it ( Fig. 6): e.g., their COI barcodes differ by 3.8% (25 bp), and therefore represents a new species. This new species keys to “ Papias sobrinus ” (J.36.2) in Evans (1955) but differs from similar-looking species by more expressed pale overscaling on somewhat darker ventral wing distal areas, smaller but visible pale spots between veins in most cells on ventral hindwing ( Fig. 152), harpe shorter, its ventral margin rounder and less extended in lateral view, dorsal margin with a tooth projecting dorsad and separated from ampulla, costa only slightly concave ( Fig. 377–379). Due to the cryptic nature of this species, most reliable identification is achieved by DNA and a combination of the following base pairs is diagnostic in the nuclear genome: aly499.36.11:A168G, aly 2680.6.3:A79T, aly 2680.6.3:C80A, aly113.6.1:G3177C, aly357.1.11:A96G, aly7186.4.1:A787A (not T), aly173.79.3:C261C (not T), aly88.15.4:C31C (not T), aly423.11.2:G129G (not A), aly529.34.2:A18A (not G), and COI barcode: T38C, T49C, A286G, T499A, T574C.
