Opoptera staudingeri (Godman & Salvin, 1894)

(Fig. 1 F, 2F, 4F, 5F, 5I, 6F)

Type locality. Panama.

Diagnosis. Male FW length 46 mm (based on specimen in Appendix 1). FW apex slightly pointed and HW margin smooth. Wings with orange-brown background. FW with a conspicuous orange postmedial band that has a narrow proximal arm, and a reduced distal arm that is barely visible inside cells M2 and M1. HW with a well-developed orange marginal band. HW outline slightly bulging below M3, which is particularly obvious in the female in Fig. 2 F. Males lack a thin hairpencil inside HW discal cell, but have a scent-pocket.

Females similar to, but paler than males. Overall gestalt similar to species of Catoblepia . Unique genitalic characters include: dorsal outline of tegumen flat in lateral view; twisted valvae; and sterigma with two large, lateral, folded over projections with jagged edges and minute spines.

Distribution. Panama, Costa Rica to Mexico (Fruhstorfer 1912, Maza & Maza 1989, Casagrande 2004).

Remarks. Casagrande (2004) lists two subspecies; the nominal staudingeri from Panama, plus mexicana Maza & Maza from Mexico (not available for examination). Opoptera staudingeri is the only species of the genus for which a description of early stages has been published (DeVries 1987).
