Type material. CHINA, Yunnan: Holotype ♂, Mt. Xiaohei (24.52°N, 98.84°E), Longling, 2009 m, 28.VII.2015, leg. KJ Teng & X Bai, slide No. GW15142. Paratypes: 1♀, other same data as holotype, slide No. GW 15143; 1♀, Nankang, Baoshan, 2009 m, 9.VIII.2014, leg. KJ Teng et al.; 1♀, Nankang, Baoshan, 2009 m, 17.VII.2015, leg. KJ Teng & X Bai.
Diagnosis. The new species is similar to S. pedella Linnaeus, 1761 in the forewing markings. It can be distinguished by the forewing with an irregular dark brown spot at distal 1/6; in the male genitalia by the dorsal margin of the cucullus roundly convex at middle; in the female genitalia by the corpus bursae with two equally sized signa. In S. pedella, the forewing lacks the spot distally; the cucullus is straight from base to apex on the dorsal margin in the male genitalia; and the corpus bursae has two differently sized signa in the female genitalia (Park 2018, Figs. 1A–3A).
Description. Adult (Fig. 10). Wingspan 19.5–22.5 mm. Head with frons silvery white mixed with yellowish brown; vertex silvery white; occiput yellowish brown, with scattered dark brown scales; in some individuals, head with frons and vertex yellowish brown. Labial palpus pale yellowish brown, with fine dark brown lines on basal 1/4 of second segment, and on ventral surface of third segment. Antenna with scape dark brown, with scattered pale yellowish brown scales; flagellum pale yellowish brown, brown on anterior margin. Collar dark greyish brown; thorax and tegula dark greyish brown, pale yellowish brown on posterior margin. Forewing yellowish white, with scattered brown scales, blackish brown along costal margin and fold; broad fascia between costal margin and anterior margin of cell, its basal 1/4 dark brown, distal 3/4 ochreous brown; irregular dark brown spot at base, elliptical dark brown spot at middle and on outer margin of cell respectively, edged with ochreous brown, spot at middle of cell reaching fold, spot on outer margin of cell reaching ventral margin; ventral margin with an ochreous brown stripe from basal 1/5 extending obliquely outward to basal 2/5 of fold, joined with spot at middle of cell; irregular dark brown spot at distal 1/6; fringe brown. Hindwing greyish brown, fringe brown. Legs yellowish brown; foreleg with femur and tibia blackish brown, tarsus blackish brown at apices of first and fifth tarsomeres; midleg with femur and tibia greyish brown, tibia with greyish brown bristles at middle and apex on dorsal surface, tarsus greyish brown at apex of each tarsomere; hind femur greyish brown on outer side, tibia greyish brown, with ochreous brown bristles at basal 1/3, 2/3 and apex on dorsal surface respectively, tarsus blackish brown at apex of each tarsomere on dorsal surface, with ochreous brown bristles at apices of basal three tarsomeres. Abdomen yellowish brown on dorsal surface, greyish brown on ventral surface.
Male genitalia (Fig. 23). Uncus subparallel from base to basal 2/3, then narrowed to straight apex, with long setae laterally. Gnathos wide basally, narrowly to rounded apex. Valva narrowed at base; cucullus sub-elliptical, length approximately 1.7 times of maximum width, dorsal margin roundly convex medially, ventral margin obtuse; inner process spine-shaped; costa small, roundly produced; sacculus banded, approximately 1/3 length of valva, pointed apically, not free from valva. Vinculum narrowly banded. Juxta V-shaped, rounded on anterior margin; anellar lobes elongate conical, approximately twice length of juxta, with short setae. Aedeagus tapered from base to apex, approximately 2/3 length of valva, with a sclerotized plate near base, with numerous microspines ranging from middle to distal 1/5, distal 1/4 produced to a club ventrally; cornutus consisting of seven denticles joined at base, located at middle.
Female genitalia (Fig. 35). 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 wide V-shape anteromedially; eighth stenite with anterior margin produced triangularly.Antrum bowl-shaped, strongly sclerotized on anterior margin. Ductus bursae approximately same length as corpus bursae, basal 2/3 almost uniform, distal 1/3 gradually widened. Corpus bursae rounded; two signa equally sized, each with a sclerotized ridge, length approximately 3/5 width of corpus bursae, located near entrance of corpus bursae and at middle respectively; two rows of about 20 large denticles at transition between ductus bursae and corpus bursae (Fig. 35a). Ductus seminalis arising from region of transition between ductus bursae and corpus bursae, broadly tubular, approximately twice length of corpus bursae, roundly inflated and curved at basal 1/3, distal 2/3 extending upward, gradually narrowed, with dense granules distally.
Distribution. China (Yunnan).
Etymology. The specific epithet is derived from the Latin ingens, referring to the large size of this species.
