Diagnosis. This species is similar to S. iwasakii in the male genitalia. It can be distinguished by the postmedian line conspicuously bending towards distal discoidal stigma in the forewing; the colliculum constricted, the corpus bursae covered with dense tiny spines and the signum absent in the female genitalia. In S. iwasakii , the postmedian line unclearly bends towards distal discoidal stigma; the diameter of the colliculum is constant throughout, the corpus bursae is covered with dense granules and the signum is stripelike.

Description. Adult ( Fig. 8 ). Forewing length 8.5–10.5 mm. Frons and vertex pale brown mixed with white. Labial palpus pale brown; first segment white ventrally at base. Maxillary palpus pale brown, white basally and distally. Antenna with scapus pale brown; flagellomeres with dorsal surface pale brown and white alternately, ventral surface pale brown. Patagium yellowish brown to pale brown. Thorax white mixed with pale brown. Tegula covered with pale brown-tipped white scales, posterior margin with long white scales. Forewing pale brown, suffused sparsely with black scales; antemedian line white, outcurved slightly; antemedian stigmata connected with antemedian line: ovate proximal discoidal stigma pale yellow edged by blackish brown, stripelike cubital stigma blackish brown; distal discoidal stigma blackish brown, tinged with pale yellow on inner side, X-shaped, separated from blackish brown spot at costa; postmedian line white, meeting costa perpendicularly, dentate towards distal discoidal stigma, outcurved near dorsum, meeting dorsum by oblique angle; fringe with basal half pale brown, distal half white. Hindwing white, slightly suffused pale brown at termen; fringe white. Legs white, foreleg covered with dense blackish brown scales on outer side, mid- and hindlegs covered with sparse pale brown scales on outer side. Abdomen grey.

Male genitalia ( Fig. 16 ). Uncus broad basally, tapering to bluntly rounded apex. Gnathos slender, slightly longer than uncus, pointed apically. Valva with same width throughout; costa straight; apex rounded. Sacculus concave ventrodistally; free distal process at two thirds of valva. Juxta ovate, narrow posteriorly. Phallus straight, nearly as long as valva; opening for ductus ejaculatorius at about basal third of phallus; four long spinelike cornuti arranged in a row.

Female genitalia ( Fig. 26 ). Papilla anale ovate, slightly shorter than apophysis posterior. Tergite eight about third as long as apophysis anterior. Antrum short tubular, slightly thicker than posterior part of ductus bursae, covered with dense granules. Colliculum constricted in anterior one fourth; ductus bursae thin and long, anterior to ductus seminalis sclerotized, anterior third membranous. Corpus bursae rounded, with dense tiny spines throughout; signum and appendix bursae absent.

Distribution. China (Sichuan).

Etymology. The specific name is derived from the type-locality Jiuzhai in Sichuan Province.
