Diagnosis. This new species is externally close to S. vesiculalis (Eecke, 1926) , but can be distinguished by the forewing with darker color and without obvious spots; uncus tapering, shrinking at middle in vesiculalis ; dorsal arm of valva broader and smooth at dorsal margin, obtuse angle at dorsal margin in vesiculalis ; apex of ventral arm rounder than vesiculalis ; harpe slightly curved to costa near apex; aedeagus straight and slightly broader at middle; coecum short, tubular.

Description. Adult (Fig. 2). Wingspan 25mm. Head white; antenna brown except white at base, bipectinate; labial palpus short, stretch forwardly, mostly covered with black scales. Thorax grayish brown, diffused with white scales. Abdomen brown, diffused with white scales. Forewing ground color brown; basal line brown, just presented at costal margin; antemedial line excurved to cell, then incurved to inner margin; medial line not obvious, similarly arc-shaped; postmedial line blackish brown, sinuous; subterminal line slight and excurved to M1, then incurved to inner margin and parallel with terminal line; terminal line dark brown; cilia brown. Hindwing grayish white, diffused with grayish brown and small dots; middle line very blurred. Male genitalia (Fig. 3): Uncus short and thin, penpoint-shaped, 1/3 times as long as tegumen; tegumen thin; valva divided at base, dorsal arm somewhat longer than ventral arm; dorsal arm broaden distally, sclerotized at costal margin; ventral arm slightly curved, sclerotized at ventral margin; harpe robust, strongly sclerotized, elongated and hook-shaped; sacculus broaden and thick, 1/3 times as long as the ventral arm of valva; saccus small and triangle-shaped; juxta anomalously triangle-shaped, and strongly sclerotized at rim. Aedeagus medium-long, weakly flat, slightly broaden at middle, shovel-shaped at extremity; coecum short tubular, 1/4 times as long as aedeagus; vesica without cornuti. Female:Unknown.

Distribution. China (Sichuan, Guangdong).

Etymology. The specific name is taken from the name of the similar species S. vesiculalis (Eecke, 1926) .
