Holotype: ♂, China, Shaanxi, Tsinling Mts, Taibaishan Mt., 33º55’N, 107º44’E, 3050 m, Aug. 2004, leg. V. Siniaev & his team ( MWM).

Paratype: ♂, same data (coll. V. Zolotuhin).

Description. Wing span 37 mm, forewing length 17.5 mm. Forewings reddish or pinkish brown, medial fasciae dark grey; hind wings darker, without streaks. The species resembles S. moltrechti in appearance being larger and with distinctly prominent pale pinkish fasciae along the external band.

Male genitalia (fig. 19): similar to congeners, but with unusual valvar shape that resembles a shoe being almost triangular, rather wide, with a characteristic angled ventral margin straight in the basal part but concave in the caudal part; dorsal margin almost straight; apical part is narrowly rounded. Saccus longer than in other congeners; juxta with low medial lobes; aedeagus short tubular with slightly curved apical spur; vesica with two zones of point-like scobination and two (caudal and cranial) lobes.

Female is unknown.

Diagnosis. Shape of valva is diagnostic; externally prominent pale pinkish fasciae along the external band are characteristic.

Bionomics. Both males were collected at light in August 2004 in high mountain forest with oaks at an altitude of 3050 m.

Distribution. The species is only known from its type locality in Shaanxi Province.
