( Figs 13 View FIGURES 9−15 , 26 View FIGURES 22−28 , 38 View FIGURES 38−39 )

Type material. CHINA, Hainan: Holotype ♂, Yajia (19°5′ N, 109°6′E), Bawangling, 261 m, 19.VII.2015, leg. QY Wang et al., slide No. GW 15152 GoogleMaps . Paratypes: 2♀, other same data as holotype, slide No. GW 15153 GoogleMaps ; 1♂ 1♀, Mt. Wuzhi, 742 m, 18. V.2015, leg. PX Cong et al.; 1♀, Yaxing Village , Nankai Town, Baisha County, 321 m, 21.VI.2015, leg. PX Cong et al .

Diagnosis. The new species is characterized in the male genitalia by the cucullus produced and almost forming a right angle before basal 1/3 dorsally, the juxta posterolaterally extended obliquely outward to a point; and in the female genitalia by having two serrate belts at transition between the ductus bursae and the corpus bursae. It is similar to S. cellifaria sp. nov., and the differences between the two species are stated in the diagnosis of the latter species.

Description. Adult ( Fig. 13 View FIGURES 9−15 ). Wingspan 8.5–10.5 mm. Head with frons shining white, vertex and occiput yellowish white. Labial palpus with second segment white on inner side, pale yellowish brown on outer side, with fine brown line basally on outer side; third segment brown. Antenna with scape yellowish white, tinged with brown scales distally on posterior margin; flagellum yellowish brown; in some individuals, antenna brown, scape white on anterior margin. Collar yellowish white, with scattered brown scales; thorax and tegula yellowish white, with scattered brown scales. Forewing pale ochreous yellow, with diffused yellowish brown spots above and below fold, with brown scales preapically; costal margin with a narrow brown streak running from base to apex; broad blackish brown stripe from basal 2/5 of cell extending obliquely inward to basal 1/4 of ventral margin, slender streak from its outer margin extending along fold to basal 3/4 of fold; elliptical blackish brown spot from outer margin of cell extending to above ventral margin, two spots linked anteriorly by a longitudinal brown streak along midline of cell; fringe brown, blackish brown around apex. Hindwing and fringe greyish brown. Legs yellowish white; foreleg with femur and tibia blackish brown on outer side, tarsus blackish brown at apices of first and fifth tarsomeres; mid tibia blackish brown at base, with shining white bristles at middle and apex, tarsus blackish brown at apices of first and fifth tarsomeres; hind tibia with long ochreous brown bristles at basal 1/3, 2/3 and apex respectively, tarsus blackish brown at apex of each tarsomere, with long ochreous brown bristles at apices of basal three tarsomeres. Abdomen ochreous brown on dorsal surface, pale ochreous brown on ventral surface.

Male genitalia ( Fig. 26 View FIGURES 22−28 ). Uncus wide at base, gradually narrowed from base to basal 4/5, parallel from distal 1/5 to apex, with long setae laterally; apex straight, approximately 1/3 width of base. Gnathos lingulate, scobinate in distal half. Tegumen bifurcate from anterior 1/3; lateral arm evenly wide. Valva narrow basally; cucullus sub-triangular, length approximately 2 times of maximum width, dorsally produced and forming a right angle at basal 1/3, ventral margin straight, apex rounded; inner process slender, hooked before apex; costa slightly produced; sacculus approximately 1/3 length of valva, wide at base, gradually narrowed from distal 1/4 to pointed apex, apically reaching base of cucullus, not free from cucullus. Vinculum narrowly banded; saccus approximately 1/3 length of uncus. Juxta rounded anteriorly, deeply incised medially from posterior margin, posterolaterally narrowed and extending obliquely outward to a point; anellar lobes elongate sub-elliptical, approximately same length as juxta, with short setae. Aedeagus approximately 3/5 length of valva, tapered from base to apex, with a sclerotized plate near base; cornutus absent.

Female genitalia ( Fig. 38 View FIGURES 38−39 ). Intersegmental membrane between papillae anales and eighth abdominal segment approximately 3 times 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 with anterior margin produced triangularly. Antrum sub-rectangular, slightly concave on posterior margin; anterior margin heavily sclerotized, with a triangular process anteromedially. Ductus bursae approximately 4/5 length of corpus bursae, basal 3/4 almost uniform, distal 1/4 gradually widened. Corpus bursae oval; signum narrow, arched in C-shape, open posteriorly, located near entrance of corpus bursae ( Fig. 38a View FIGURES 38−39 ); two serrate belts at transition between ductus bursae and corpus bursae: longer one arched, shorter one straight. Ductus seminalis arising from middle of corpus bursae, broadly tubular, narrowed from base to apex, approximately 2/3 length of corpus bursae, with dense granules.

Distribution. China (Hainan).

Etymology. The specific epithet is derived from the Latin serr- and fasciarius, referring to the two serrate belts at the transition between the ductus bursae and the corpus bursae.
