Diagnosis. The new species can be distinguished from its congeners by the blackish brown forewing with two shining yellow spots; in the male genitalia by the gnathos heavily sclerotized distally and the cucullus dilated spherically; in the female genitalia by the corpus bursae with two large same sized signa only slightly shorter than the length of the corpus bursae. It is similar to S. laiyangensis sp. nov. superficially, but can be distinguished in the male genitalia by the gnathos without a longitudinal pleat mediodistally, the hooked inner process of the valva and the distal process of the aedeagus about 1/3 the length of the aedeagus. In S. laiyangensis sp. nov., the gnathos has a longitudinal pleat mediodistally, the inner process of the valva is slenderly clubbed and the elongate rectangular distal process is about half the length of the aedeagus.

Description. Adult ( Fig. 16 View FIGURES 13‒19 ). Wingspan 7.5‒8.0 mm. Head with frons silvery grey; vertex dark bronzy brown; occiput blackish brown. Labial palpus blackish brown except second segment yellowish white on inner surface. Antenna blackish brown; flagellum blackish brown annulated with yellow. Collar blackish brown. Thorax and tegula yellow on anterior half, blackish brown on posterior half. Forewing blackish brown, with purplish shining; with two yellow spots: antemedian spot before basal 1/3, slightly narrowed to below costal margin; postmedian spot sub-rounded, at basal 2/3; fringe blackish brown. Hindwing and fringe brown. Legs pale ochreous yellow dorsally, cream white ventrally: foreleg with tibia blackish brown on outer surface and tarsus blackish brown at apex of each tarsomere; midleg with tibia blackish brown at base, middle and apex on dorsal surface, with pale yellowish brown bristles at middle and apex, tarsus blackish brown at apex; hindleg with tibia annulated with black and bearing long blackish brown bristles at middle and apex, tarsus annulated with black and bearing long blackish brown bristles at apices of basal three tarsomeres, fourth and fifth tarsomeres silvery white. Abdomen dark brown on dorsal surface; greyish white on ventral surface, except fourth and fifth segments blackish brown.

Male genitalia ( Figs 41a–b View FIGURES 39‒45 ). Uncus wide at base, with long setae laterally, slightly narrowed to basal 2/3, distal 1/3 almost uniformly wide, obtuse at apex. Gnathos wide at base, narrowed to apex, heavily sclerotized distally. Tegumen with height twice length of uncus. Valva sub-rectangular; cucullus spherical, setose, shorter than half length of valva; inner process hooked; costa slightly concave at middle; sacculus 5/6 length of valva, concave at basal 1/3 on ventral margin, apex rounded, reaching before apex of cucullus. Vinculum narrowly banded. Juxta subrounded, broadly obtuse on posterior margin; anellar lobes oval, about same length as juxta. Aedeagus 1.5 times length of valva, with a sclerotized plate near base, with numerous spicules between middle and basal 3/5, tubular from base to basal 2/3; distal process about 1/3 length of aedeagus, spatulate distally; cornutus absent.

Female genitalia ( Fig. 62 View FIGURES 62‒66 ). Papillae anales longer than wide, with short setae. 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. Eighth segment straight on posterior margin, with long setae; eighth tergite concave in V shape anteromedially; eighth sternite triangularly produced anteriorly. Antrum sub-rectangular, slightly concave on anterior margin. Ductus bursae almost uniformly wide, 1.2 times length of corpus bursae, with 23‒25 denticles in anterior half on right side. Corpus bursae sub-oval, with two large same sized signa slightly shorter than corpus bursae: one longitudinally bow-shaped, with numerous microspines around, the other elongate rhombic, serrate on one side, with a sclerotized median ridge. Appendix bursae elliptical, originating from corpus bursae posteriorly; ductus seminalis originating from middle of ductus bursae, elongate tubular; bulla elliptical, located beyond middle.

Distribution. China (Hainan, Yunnan).

Host plant. Glochidion assamicum (Muell. Arg.) (Euphorbiaceae) .

Etymology. The specific epithet is derived from the Latin sphaeroideus, referring to the shape of the cucullus of the male genitalia.
