1’) Forewings with supernumerary crossveins on corium and clavus ............................... 3
2) Crownfrons transition with carina only on median portion, not continuous with carina on antennal ledges; forewings light brown maculate with translucent white ( Fig. 1 View FIGURE 1 D); male pygofer with posterior margin forming a lobe bearing short stout macrosetae ( Fig. 2 View FIGURE 2 A); subgenital plates much shorter than pygofer ( Fig. 2 View FIGURE 2 A); aedeagus with single apical process ( Fig. 2 View FIGURE 2 D); female unknown...................................... O. freytagi View in CoL sp. nov.
2’) Crownfrons transition with carina complete, continuous with carina on antennal ledges; forewings translucent yellow with few small lighter yellow spots at base ( Fig. 1 View FIGURE 1 B); male pygofer without setigerous lobe ( Young 1977: Fig. 232c); subgenital plates extending posteriorly beyond pygofer apex ( Young 1977: Fig. 232c); aedeagus with pair of apical processes ( Young 1977: Figs 232f, p); female sternite VII with very elongate lateral margins ( Cavichioli & Wyler 1992: Fig. 4 View FIGURE 4 ).......... O. bracteata Young View in CoL
3) Forewings mostly dark with large unpigmented oblique area on basal half of clavus (usually covered with brochosomes) ( Figs 1 View FIGURE 1 F, G) ...................................................... 4
3’) Forewings variably colored, but without large unpigmented area on basal half of clavus ( Figs 1 View FIGURE 1 A, C, E, H) .................................................................................................. 5
4) Females smaller, 12.3–13.3 mm; forewings dark brown to black ( Fig. 1 View FIGURE 1 F); male pygofer with apical margin serrate ( Fig. 4 View FIGURE 4 A); aedeagus with dorsal robust elongate process extending from base posteriorly beyond apex of shaft ( Fig. 4 View FIGURE 4 D); female sternite VII with posterior margin broadly round and without median projection ( Fig. 4 View FIGURE 4 G); female pygofer with macrosetae along most of posteroventral margin ( Fig. 4 View FIGURE 4 I) ........... .......................................................................................................... O. orphne View in CoL sp. nov.
4’) Females larger, approximately 14.9 mm; forewings dark red ( Fig. 1 View FIGURE 1 G); male unknown; female sternite VII with small median projection on posterior margin ( Fig. 5 View FIGURE 5 A); female pygofer with few macrosetae restricted to dorsal anteapical region ( Fig. 5 View FIGURE 5 C) ... ...............................................................................................
