Diagnosis. Opsiphanes cassiae differs from Opsiphanes bogotanus and Opsiphanes mexicana stat. nov., the closest related species, in having the VHW with a smaller eyespot between Sc+R 1 and M 1, usually not reaching M 1, and in the absence of a dark-brown band extending from the base of the wing to this eyespot ( Fig. 20a View FIGURE 20 ). Molecular analyses recovered Opsiphanes cassiae as closely related to Opsiphanes bogotanus and Opsiphanes mexicana stat. nov. ( Fig. 2 View FIGURE 2 ) (genetic distance 1.6–2.7% and 2.0–2.5%, respectively).

Male genitalia. Tegumen in dorsal view with the anterior and posterior margins of equal width; anterior projection of saccus in lateral view less than twice as long as dorsal arms of saccus ( Fig. 28 View FIGURE 28 ).

Female genitalia. Lamella antevaginalis membranous medially and sclerotized laterally; lamella postvaginalis pointed antero-medially and rounded postero-medially; ostium membranous ( Fig. 29 View FIGURE 29 ).

Variation. Subspecies vary in the following characters: DFW, the width, length, and color of the oblique band; the discal cell may or may not have a small yellow spot. DHW, the marginal band ranges from faint to absent. HW, the crenulation of the outer margin; the anal region varies from rounded to slightly pointed. VFW, the width and color of the oblique band; EIII submarginal line extends or not to CuA 2. VHW, the size and shape of the eyespot between Sc+R 1 and M 1, and the width of its dark-brown ring; and the size and shape of the eyespot between M 3 and CuA 2 ( Figs 20–27 View FIGURE 20 View FIGURE 21 View FIGURE 22 View FIGURE 23 View FIGURE 24 View FIGURE 25 View FIGURE 26 View FIGURE 27 ).
