Opoptera bracteolata Stichel, 1901, NEW STATUS

(Fig. 1 H, 4H, 5H)

Type locality. Bolivia.

Diagnosis. Male FW length range 39.8–41.3 mm (based on specimens in Appendix 1). Wings with orange-brown background. FW orange postmedial band markedly reduced, broken into a series of independent spots that do not reach the anterior FW margin. HW with a thin orange marginal band. Males have a thin hairpencil inside HW discal cell, contrasting other species in the aorsa -group.

Distribution. Bolivia (Casagrande 2004).

Justification for new status. Opoptera bracteolata shows important differences from O. arsippe that justify full species status. These two taxa have distinctive, easily diagnosable wing color patterns, and males have different wing scent organs (compare Fig. 1 H and G). Opoptera bracteolata and O. arsippe also have rather different male genitalia (Fig. 4 H and G, 5H and G), and such structural differences further support the notion that they are separate species. It is unknown to me whether these two taxa overlap geographically. Note that the specimen listed by Penz (2007) as O. arsippe actually corresponds to O. bracteolata .

Remarks. I was unable to obtain females of this species for examination.
