DESCRIPTION. Male (holotype) ( Figs 2–3 View Figs 2–3 ). Alar expanse 32.8 mm; body length 19.1 mm; forewing 15.0 mm; antenna 8.0 mm.

Head with antenna black with dark blue-violet sheen dorsally and dark brown ventrally; scapus dark gray-brown with greenish-blue sheen and a few yellowish scales laterally; frons dark brown with bright greenish-violet sheen and a very narrow gray stripe laterally; labial palpus orange with a few thin, elongate, black scales both externally and dorsally on mid joint; vertex black with anthracite sheen; pericephalic hairs orange with an admixture of black hair-like scales dorsally.

Thorax with patagia orange with an admixture of a few black scales with greenish-violet sheen dorsally; tegula, meso- and metathorax and thorax laterally entirely black with bright greenish-violet sheen; posteriorly dark gray with greenishbronze sheen covered with long white hair-like scales. Legs with neck plate orange with a few black scales with greenish sheen laterally; fore, mid and hind legs entirely black with violet-anthracitic sheen; both fore femur and fore tibia posteriorly with elongate hair-like scales forming a well-visible tuft; spurs mid and hind tibiae dark gray with anthracitic sheen internally. Forewing completely opaque; dorsally black with bright blue-violet sheen; cilia dark brown to black with dark violet sheen; ventrally dark brown to black with bright blue sheen gradually changing to violet distally of cross-vein; cilia dark brown to black with bronze-violet sheen. Hindwing with scales black with bright blue sheen dorsally and blue-violet sheen ventrally; with seven oval transparent areas in cell proximally of discal spot, distally of discal spot between veins M 1 –CuA 1 and CuA 2 –anal margin; cilia dark brown to black with dark violet sheen dorsally and bronze-violet sheen ventrally.

Abdomen entirely black with bright blue-violet sheen; anal tuft with a few white with yellowish tint scales laterally.

Male genitalia (holotype) (genital preparation № OG– 001-2021) ( Figs 4–7 View Figs 4–7 ). Uncus long, narrow, slightly broadened medially, with simple setae laterally; tegumen short; gnathos narrow, with triple tooth; tuba analis with subscaphium narrowly sclerotized ( Fig. 4 View Figs 4–7 ); valva ( Fig. 5 View Figs 4–7 ) valva broad, ovoid and relatively short, with dorsal half covered with strong hand-shaped setae, a row of such setae medially and a stripe of pointed setae subventrally; crista sacculi low, with a patch of strong pointed setae; saccus ( Fig. 6 View Figs 4–7 ) slightly shorter than vinculum, straight, narrow, somewhat broadened and rounded basally; aedeagus ( Fig. 7 View Figs 4–7 ) rather broad, somewhat longer than valva, distally with a hook-shaped well-sclerotized carina penis dorsally and a sclerotized plate ventrally; vesica with numerous rows of minute flat cornuti.

Female. Unknown.

INDIVIDUAL VARIABILITY. Unknown.

DIFFERENTIAL DIAGNOSIS. By the conformation of the hindwing this new species is somewhat similar to S. kalliesi Arita et Riefenstahl, 2004 , but it differs by the colouration of the antenna (antenna orange in S. kalliesi ), by the presence of transparent areas between veins M 1 and M 2 and CuP and 1A of the hindwing [all these cells opaque in S. kalliesi ; compare Fig. 2 View Figs 2–3 with fig. 1 in Arita, Riefenstahl, 2004: 117], and by the structure of the male genitalia, especially by the shape of the gnathos (with double tooth in the species compared) and valva [compare Figs 4–7 View Figs 4–7 with fig. 2 in Arita, Riefenstahl, 2004: 117]. From all other congeners this new species is clearly distinguishable by the orange patagia, structure of the transparent cells of the hindwing and by te conformation of the male genitalia.

BIONOMICS. The larval host plant is unknown. The holotype was collected in early February with help of unspecific artificial sex pheromones. At least four specimens were attracted from which, unfortunately, only one was collected. They came to the lures from about 7.30 am to 10 am local time.

HABITAT. The holotype was collected at the edge of a coconut plantation and a secondary rainforest ( Fig. 1 View Fig ).

DISTRIBUTION. The new species is known only from the type locality on the island of Bali, Indonesia .

ETHYMOLOGY. This new species is named after the island Bali, Indonesia, where this species was collected.
