Key to species of the Schinia chrysellus complex

1. Forewing with reniform spot mostly incorporated into median band ( Figs. 4–9 ) ....... 2

1’. Forewing with reniform spot barely coalesced or separate from median band ( Figs. 10–15 ) .......................................................................................................................... 3

2. Ventral lip of frons greatly produced, labial palp barely extending past frons ( Fig. 16 ); foretibial claws flat, apices rounded ( Fig. 21 ); apex of forewing lacking a small black patch of scales that extends onto fringe ......................................................... chrysellus

2’. Ventral lip of frons produced, labial palp projecting well beyond frons ( Fig. 17 ); foretibial claws round, slender, apices pointed ( Fig. 22 ); apex of forewing with a small black patch of scales that extends onto fringe ........................................... chryselloides

3. Forewing with a wide median band (width approximately 25% of forewing length) ( Figs. 10–11 ); reniform spot either separate or barely coalesced with median band

( Figs. 10–11 ); scales on thorax narrow overlaying wide scales; foretibial claws flat with rounded apices ( Fig. 23 ) .............................................................................. alencis 3’. Forewing with a narrow median band (width approximately 15% of forewing length) ( Figs. 12–15 ); reniform spot barely coalesced with median band ( Figs. 12–15 ); scales on thorax wide, no narrow scales; foretibial claws slender with pointed apices ( Figs. 21–22, 24–25 ) .............................................................................................................. 4

4. Median band of forewing tan to rufous, variously infused with black scales ( Figs. 12– 13 ); thorax dark rufous, not concolorous with median band ................................ ciliata

4’. Median band of forewing bright cinnamon­rufous, lacking black scales ( Figs. 14–15 ); thorax concolorous with median band ...................................................... rufocostulata
