KJ Teng et al. Diagnosis. The new species is characterized by the brownish ochreous forewing with two yellowish white markings. It is similar to S. citrinella Sinev, 1995, but can be distinguished in the male genitalia by the cucullus obtusely rounded at apex, and the elongate elliptical anellar lobes; and in the female genitalia by the sub-rectangular antrum and the ductus seminalis with a row of clustered short spines distally. In S. citrinella, the cucullus is truncate at apex, and the anellar lobes are elongately clubbed; the antrum is bowl-shaped and the ductus seminalis has several denticles at apex. Description. Adult (Fig. 6). Wingspan 12.5–14.5 mm. Head with frons silvery white, vertex silvery white, mixed with ochreous, occiput ochreous. Labial palpus cream white on inner surface, pale yellow on outer surface, second segment dark brown in basal 1/3 on outer surface. Antenna with scape silvery white, ochreous on posterior margin; flagellum pale yellow. Thorax and tegula ochreous, mixed with cream white scales. Forewing brownish ochreous, dark ochreous between fold and ventral margin in basal 1/4; yellowish white fascia from distal 1/5 of costal margin extending obliquely inward to distal 1/3 of ventral margin, mixed with ochreous; ventral margin with a yellowish white spot at basal 1/3, narrowed obliquely inward to base of fold; fringe brown. Hindwing dark grey, fringe brown. Legs yellowish white; fore femur and tibia black on outer side, tibia ochreous brown dorsally, tarsus black at apex; mid tibia with long pale ochreous bristles at middle and apex on dorsal surface, tarsus black at apex; hind tibia with long ochreous brown bristles at apex, tarsus annulated with blackish brown and bearing long ochreous brown bristles at apices of basal three tarsomeres, black at apex. Abdomen greyish yellow on dorsal surface, yellowish white on ventral surface. Male genitalia (Fig. 19). Uncus wide at base, gradually narrowed to basal 3/4, evenly narrow from distal 1/4 to rounded apex, with sparse long setae laterally. Gnathos slightly narrowed to apex; apex rounded, with a tooth medially. Tegumen with height approximately twice length of uncus. Valva sub-rectangular; cucullus sub-quadrate, straight on dorsal margin, obtuse on ventral margin, obtusely rounded at apex; inner process narrowed and curved distally; costa convex roundly; sacculus narrowly banded, concave at basal 2/5 of ventral margin, apex rounded and free from cucullus, reaching before apex of valva. Vinculum narrowly banded; saccus approximately 1/5 length of uncus. Juxta turbinate, pointed anteromedially, straight on posterior margin; anellar lobes elongate elliptical, with dense setae. Aedeagus 1.3 times length of valva, tapered from base to apex, with a sclerotized plate near base, with numerous spicules ranging from basal 1/4 to distal 3/10; distal process 1/3 length of aedeagus, relatively wide, narrowed from preapex to pointed apex. Female genitalia (Fig. 32). Intersegmental membrane between papillae anales and eighth abdominal segment approximately twice length of papillae anales. Apophyses posteriores approximately 1.8 times length of apophyses anteriores. Eighth segment straight on posterior margin, with long setae; eighth tergite sub-rectangular; eighth stenite produced anteriorly. Antrum sub-rectangular, obtusely rounded on anterior margin. Ductus bursae approximately 2/3 length of corpus bursae, gradually widened to corpus bursae. Corpus bursae elongate elliptical; with two differently sized signa, each with a sclerotized ridge, larger one approximately four times length of smaller one, serrate on posterior margin, smaller one with serrate margin on anterior margin. Ductus seminalis originating from anterior part of ductus bursae, with several denticles basally, with a row of clustered short spines distally (Fig. 32a). Distribution. China (Yunnan). Etymology. This specific epithet is derived from the Latin ochr- and coloratus, referring to the colour of the forewing.
