Diagnosis. The new species is similar to S. serrifasciaria sp. nov. It can be distinguished by the cell with a longitudinal streak extending straightly to preapex; in the male genitalia by the uncus rounded at apex, the sub-elliptical cucullus roundly produced at middle on the dorsal margin and the aedeagus with a cornutus; in the female genitalia by the corpus bursae with two signa, and the ductus seminalis approximately twice the length of the corpus bursae. In S. serrifasciaria sp. nov., the cell has a longitudinal streak from basal 2/5 reaching the outer margin of the cell; the uncus is straight at apex, the sub-triangular cucullus is produced at basal 1/3 on the dorsal margin and the aedeagus lacks a cornutus in the male genitalia; the corpus bursae has one signum, and the ductus seminalis is approximately 2/3 the length of the corpus bursae in the female genitalia.

Description. Adult ( Fig. 4 ). Wingspan 11.0–14.0 mm. Head with frons and vertex greyish white; occiput pale ochreous brown, with scattered brown scales. Labial palpus greyish white on inner side, pale ochreous brown on outer side. Antenna pale yellow, scape greyish white on anterior margin; flagellum annulated with brown. Thorax and tegula brown in anterior half, pale yellow in posterior half. Forewing yellowish white, with scattered brown scales basally, dark brown along basal 2/3 of costal margin; longitudinal dark brown streak from basal 2/5 of cell extending straightly to preapex, widened ventrad basally, with a greyish brown spot from below its distal 1/3 extending to above ventral margin; dark brown fascia running from basal 1/3 to preapex of fold; ventral margin with a blackish brown spot at base; fringe dark brown. Hindwing and fringe greyish brown. Legs ochreous brown dorsally, yellowish white ventrally; fore femur and tibia blackish brown on outer side, tarsus blackish brown at apex of first tarsomere; mid tibia purplish brown in basal half on dorsal surface, with pale yellowish brown bristles at middle and apex; hind tibia with long ochreous brown bristles at basal 1/3, 2/3 and apex on dorsal surface respectively, tarsus annulated with blackish brown at apex of each tarsomere, with ochreous brown bristles at apices of basal three tarsomeres. Abdomen yellowish brown on dorsal surface, yellowish white on ventral surface.

Male genitalia ( Fig. 17 ). Uncus sub-triangular, gradually narrowed from base to apex, with long setae laterally. Gnathos elongate triangular, narrowly rounded at apex. Tegumen with anterior half bifurcate; lateral arm narrowed anteriorly, with a process at posterior 2/5 of its inner margin respectively. Valva subparallel from base to cucullus; cucullus sub-elliptical, length approximately 1.5 times of maximum width, dorsal margin produced roundly at middle, ventral margin obtuse, apex rounded; inner process slender, curved inward beyond middle by a right angle; costa sub-rounded; sacculus broadly banded, approximately 2/5 length of valva, apex narrowly rounded, slightly free from cucullus. Vinculum narrowly banded; saccus short triangular, approximately 1/4 length of uncus. Juxta V-shaped, anterior margin broadly rounded; anellar lobes elliptical, with short setae. Aedeagus tapered from base to apex, approximately 4/5 length of valva, with a sclerotized triangular plate near base and numerous microspines ranging from basal 1/4 to middle, distal 1/4 produced to a thin club ventrally; cornutus consisting of four spines joined at base, located at basal 1/3 ( Fig. 17a ).

Female genitalia ( Fig. 30 ). Intersegmental membrane between papillae anales and eighth abdominal segment approximately 2.5 times length of papillae anales.Apophyses posteriores approximately 1.5 times length of apophyses anteriores, slenderer than apophyses anteriores. Eighth segment straight on posterior margin; eighth tergite subrectangular; eighth stenite with anterior margin produced. Antrum sub-rectangular. Ductus bursae approximately same length as corpus bursae, basal 3/4 almost uniform, distal 1/4 gradually widened. Corpus bursae elongate oval; with two signa, each with a sclerotized ridge: larger signum with short fine spines anteriorly, serrate on posterior margin, approximately twice length of smaller signum; two rows of large denticles at transition between ductus bursae and corpus bursae. Ductus seminalis arising from region of transition between corpus bursae and ductus bursae, approximately twice length of corpus bursae, widened elliptically at basal 1/3, broad in distal 2/3, spiral from before apex, with dense granules preapically.

Distribution. China (Beijing, Fujian, Yunnan, Zhejiang).

Etymology. The specific epithet is derived from the Latin cell- and farius, referring to the longitudinal streak in the cell.
