The holotype and female paratype are deposited in the collection of Jagello University Krakov , Poland ; 2 male paratypes are deposited in the collection of Hungarian National Museum , Budapest, Hungary .

Diagnosis. Dimorphic species with larger females, differing from other species by narrow forewing with almost parallel margins, and brownish wing coloration with green suffusion. Close to S. lichenosella in male genitalia, but differs by wider uncus, extremely broad sacculus and shorter valva.

Description. Adult ( Fig. 29 View FIGURES 25–32 ). Wingspan: male 20 mm, female 25 mm. Forewing strongly arched basally, with almost parallel costal and ventral margins and straight outer margin. Head, thorax and ground color of forewing brown with greenish tint, especially expressed in basal part of wing; basal field grey-brown, with brown streaks on ventral margin; subbasal area to mid part of wing brown with green suffusion, antemedial line indistinct; outer part of medial field brown; orbicular not expressed, reniform marked as blackish dash; postmedial line indistinct, marked by twin row of dark dots; subterminal and terminal fields separated by a diffused waved line; terminal line expressed as row of blackish spots; cilia dark brown. Hindwing pale yellowish grey, with distinct discal spot and subterminal band; cilia pale yellowish grey.

Male genitalia ( Fig. 47 View FIGURES 45–48 ). Uncus reduced, short, but wider than in S. lichenosella ; tegumen and vinculum narrow, vinculum two times higher than tegumen; juxta narrow, constricted medially; transtilla with wide sclerotized plates; valva with extreme basally broad and large sacculus, constricted apically and with sticklike short apical part with cucullus covered with dense setae. Aedeagus rather large, straight, vesica tubular, curved, with minute cornuti in apical part.

Female genitalia ( Fig. 70 View FIGURES 63–71 ). Ovipositor short, papillae anales moderate, apophyses anterior about 1/3 longer than posterior ones; antrum large, cup-like, asymmetrical; ductus bursae sclerotized, cervix bursae membranous; bursa rounded, membranous, ribbed.

Distribution. ( Fig. 85 View FIGURES 79–86 ). North Vietnam. The species is known only from its type-locality, a mountainous region.

Etymology. The species name is derived from the characteristic large sacculus.
