(Fig. 3 part, 93–94, 315–317)

Definition and diagnosis. Genomic analysis reveals that a female from Tingo Maria, Peru, identified as Festivia grippa (Evans, 1953) (type locality in eastern Ecuador), is genetically differentiated from it (Fig. 4), e.g., COI barcode difference of 2.3% (15 bp) and because no published names apply to it, represents a new species. This new species keys to “ Sostrata grippa ” (E.42.5) in Evans (1953) and differs from its relatives by a combination of the following characters: forewing discal cell with one large upper hyaline spot (lower spot absent), the two segments of the hyaline spot in forewing cell CuA 1 -CuA 2 are connected to each other at their bases on both dorsal and ventral sides, ventral forewing blue basal overscaling broader, extends from costa to cover discal cell, cell CuA 2 -1A+2A with a pale spot at 1/3 from its base, ventral hindwing with an apical blue spot and the dark brown streak in cell Sc+R 1 -RS is smaller and separated from vein Sc+R 1 by blue (Fig. 93–94). Due to the cryptic nature of this species and unexplored phenotypic variation, most reliable identification is achieved by DNA and a combination of the following base pairs is diagnostic in the nuclear genome: aly 2700.10.9:G42A, aly300.20.2:G126A, aly116.12.4:G66T, aly 2578.2.1:A22C, aly536.138.7:A319C, aly 1260.2.1:T124T (not C), aly10226.27.3:A51A (not T), aly4523.3.2:C153C (not T), aly235.8.17:T150T (not C), aly10235.5.16:C81C (not T), and COI barcode: T139C, T287C, T319A, 514T, A526T, T619C.
