Opoptera arsippe (Hoppfer, 1874)
(Fig. 1 G, 1K, 2G, 4G, 5G, 5J)
Type locality. Peru.
Diagnosis. Male FW length range 41.7–43.7 mm (based on specimens in Appendix 1). Wings with orange-brown background. FW with a thin orange postmedial band that can be disjointed at cell M3, and a reduced distal arm that does not reach the apical white spots. HW margins with very shallow depressions, as compared to other species of Opoptera . HW with a conspicuous orange marginal band, including the tail. Males lack a thin hairpencil inside HW discal cell, but instead have a conspicuously long, broad and dark hairbrush in the cell that extends over the open scent organ next to vein Cu2. The scent organ next to Cu2 consists of a shallow concavity on the wing surface.
Distribution. Peru, Bolivia? (Casagrande 2004).
Remarks. I was unable to obtain females of this species for examination. Casagrande (2004) lists two subspecies; the nominal arsippe from Peru, and bracteolata Stichel from Bolivia, elevated here to full species (see below).
