Description.

Male, wingspan 32 mm (Figs 4-6 ). Forewing pale brown, a pale antemedial line, acutely angled in interno-median interspace with fuscous brown rectangular patch on its inner area and a similar postmedial line acutely angled at vein M1 (in one Golitar (Sikkim) specimen, angled antemedial line touches postmedial line at vein Cu2; Fig. 4 ); area between two lines pale brown with oblique ferruginous reniform spot. Hindwing pale; traces of a waved submarginal line; underside paler with similar markings. Thorax with long, brown patagia. Male genitalia (Figs 23 , 24 ). Uncus broad, laterally folded, apically rounded; gnathos short and well developed, reaching up to midst of uncus, tip hooked; valva simple, without any process; tegumen broad; transtilla broad, a sclerotised flap-like process originating medially; juxta long, broad, slightly constricted at apex; vinculum U-shaped; aedeagus long, sclerotized carinal plate with numerous spikes; vesica membranous with fine scobination, cornuti absent.

Diagnosis.

Among the Sacada species reported from India, S. discinota is externally similar to S. sikkima and S. constrictalis due to the highly angled antemedial and postmedial lines, but it is distinct from both of these congeners by its paler hindwings.
