The new species is similar to S. stimulata Meyrick, 1913 . It can be distinguished in the male genitalia by the cucullus obtusely angled at basal 1/4 on the dorsal margin, and the cornutus consisting of seven spines; in the female genitalia by the transition between the ductus bursae and the corpus bursae with two rows of denticles and the corpus bursae with two large signa more than half median width of the corpus bursae. In S. stimulata , the cucullus is right-angled at base and the cornutus consisting of 3–5 spines in the male genitalia; and the transition between the ductus bursae and the corpus bursae lacks denticles and the corpus bursae has two small signa less than 1/4 of the median width of the corpus bursae in the female genitalia. Description. Adult ( Fig. 5 ). Wingspan 15.0–19.0 mm. Head with frons and vertex silvery white, occiput pale yellowish brown. Labial palpus with second segment milky on inner side, outer side pale yellowish brown, with fine dark brown line basally; third segment pale yellowish brown. Antenna pale yellowish brown, scape brown dorsally. Collar purplish brown medially, ochreous yellow laterally; thorax and tegula yellowish brown, with scattered blackish brown scales. Forewing yellowish brown, with scattered ochreous scales, with a few brown scales at distal 1/6; blackish brown scales at base from below costal margin to above fold as well as between fold and ventral margin respectively, forming large ill-defined spots; blackish brown streak along basal 2/3 of costal margin, wide at base, gradually narrowed to basal 2/3; cell with a faint elliptical dark brown spot at middle, an elongate elliptical ochreous brown spot on outer margin, both diffused toward ventral margin, edged with ochreous scales, indistinct in some individuals; ventral margin with a blackish brown spot from basal 1/5 extending to fold; fringe pale yellowish brown, blackish brown around apex. Hindwing greyish brown, fringe pale greyish brown. Foreleg yellowish white, femur and tibia purplish brown on outer side, tibia with ochreous yellow bristles at middle and apex, tarsus blackish brown at apex; midleg milky, tibia purplish brown in basal 1/3 on dorsal surface, with long milky bristles at basal 1/3 and apex, tarsus blackish brown at apex; hindleg yellowish brown, tibia with scattered brown scales, with long blackish brown bristles at basal 1/3 and 2/3, mixed with yellowish white, ringed with long ochreous yellow bristles distally, tarsus blackish brown at apex of each tarsomere, ringed with long ochreous yellow bristles at apices of basal three tarsomeres. Abdomen yellowish brown on dorsal surface, greyish white on ventral surface. Male genitalia ( Fig. 18 ). Uncus wide at base, narrowed from base to apex, with long setae laterally; apex approximately 1/4 width of base. Gnathos triangular, pointed at apex. Tegumen bifurcate from posterior 2/5; lateral arm narrowed anteriorly, with a small digitate process at middle on inner margin. Valva narrow basally; cucullus very large, length approximately 1.5 times of maximum width, strongly convex at basal 1/4 on dorsal margin, forming a large obtuse angle, obliquely straight from basal 1/4 to apex, ventral margin obtuse; inner process slender, curved inward at middle by a right angle; costa slightly produced; sacculus wide at base, narrowed to apex, approximately 1/3 length of valva, apex pointed, not free from cucullus. Vinculum narrowly banded; saccus approximately half length of uncus. Juxta V-shaped, pointed anteromedially; anellar lobes elongate elliptical, approximately twice length of juxta, with short setae. Aedeagus approximately 3/4 length of valva, tapered from base to apex, with a sclerotized plate near base, with a tuft of small denticles located at middle ventrally, distal 1/4 produced to a thin club ventrally; cornutus consisting of seven large denticles joined at base, located at middle. Female genitalia ( Fig. 31 ). Intersegmental membrane between papillae anales and eighth abdominal segment approximately 3 times length of papillae anales. Apophyses posteriores approximately 1.5 times length of apophyses anteriores. Eighth segment straight on posterior margin, with long setae; eighth tergite concave in V shape anteromedially; eighth stenite with anterior margin produced. Antrum sub-rectangular, strongly sclerotized on anterior margin, slightly produced anteromedially. Ductus bursae approximately 3/4 length of corpus bursae, basal 2/3 almost uniformly narrow, distal 1/3 slightly widened. Corpus bursae oval, with dense small granules; with two large, equally sized signa, more than half width of corpus bursae, with sclerotized ridge, located posteriorly and medially; two rows of large denticles at transition between ductus bursae and corpus bursae. Ductus seminalis arising from region of transition between ductus bursae and corpus bursae, approximately 1.5 times length of corpus bursae, dilated and curved upward at basal 1/4, distal 3/4 broadly tubular, with dense small granules at apex. Distribution. China ( Yunnan ). Etymology. The specific epithet is derived from the Latin cornutus , referring to the cucullus strongly convex at dorsal 1/3, forming an obtuse angle.
