Sacada decora Walker, 1862 Fig. 14

Sacada decora Walker 1862: 136.

Description.

Male, wingspan 25.4 mm (Fig. 14 ). Rosy red; forewing with antemedial line outwardly oblique, broadly and inwardly rounded at vein Cu2 to meet inner margin, where a black patch is present towards its inner edge; two black discal spots; an inwardly oblique, paler postmedial line followed by a broad band of fuscous scales, which is diffusing towards termen. Hindwing paler, a diffused postmedial line present.

Diagnosis.

Because of the smoothly curved postmedial line (not strongly angled), S. decora is externally similar to S. inordinata , S. dzonguensis , S. umtasorensis , and S. pallescens , but it differs from three of these four species having its hindwing paler, and from S. pallescens in having the antemedial line outwardly oblique and broadly and inwardly rounded at vein Cu2.
