The phylogeny of Opoptera butterflies, and an assessment of the systematic position of O. staudingeri (Lepidoptera, Nymphalidae) Author Penz, Carla M. text Zootaxa 2009 1985 1 20 journal article 10.5281/zenodo.185409 1e8adb1d-85ac-48e8-98ba-42355c1d777a 1175-5326 185409 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).
