Diagnosis. This species is similar to S. tohokuensis by the convex costa and free distal process nearly reaching the apex of the valva in the male genitalia. It can be distinguished from S. tohokuensis by the posterior half of the juxta dividing into two branches and the phallus bearing more than twenty cornuti in the male genitalia; the colliculum longer than half length of the ductus bursae, and the ductus bursae curving three times in the female genitalia. In S. tohokuensis , the juxta is long ovate, and the phallus has a single cornutus; the colliculum is about one fourth as long as the ductus bursae, and the ductus bursae is curved once.

Description. Adult ( Fig. 6 ): Forewing length 5.0– 5.5 mm. Frons white to pale brown. Vertex white. Labial palpus blackish brown; first segment white ventrally at base; third segment white distally. Maxillary palpus blackish brown, white basally and distally. Antenna with scapus blackish brown dorsally, pale brown mixed with white ventrally; flagellomeres blackish brown and white alternately on dorsal surface, pale brown on ventral surface. Patagium and tegula blackish brown. Thorax white mixed with pale brown. Forewing sparsely suffused with blackish brown scales; antemedian line white, anterior two thirds oblique outwards, angled at posterior third, then oblique inwards; antemedian stigmata connected with antemedian line: ovate proximal discoidal stigma brown tinged with pale yellow, stripelike cubital stigma blackish brown; distal discoidal stigma blackish brown, tinged with pale yellow on inner side, 8-shaped, connected with blackish brown spot at costa; postmedian line white, meeting costa and dorsum perpendicularly, bent towards distal discoidal stigma in inconspicuous dentation, outcurved near dorsum as small dentation; fringe white, with pale brown subbasal line. Hindwing white to pale brown; fringe with white basal line, followed by pale brown line, distal half greyish. Legs white, covered with sparse blackish brown scales on outer side; tarsi white and blackish brown alternately on outer side. Abdomen pale brown.

Male genitalia ( Fig. 14): Uncus ovate. Gnathos slender, slightly shorter than uncus, pointed apically. Valva more or less arched; costa gently convex, with small slender basal prong; apex rounded. Sacculus convex ventrobasally, concave ventrodistally; free distal process nearly reaching apex of valva. Juxta broadened from slightly narrow base to about middle, then divided into two broad branches, posteriorly forming V-shaped incision. Phallus straight, about four fifths as long as valva, medially covered with dense granules; opening for ductus ejaculatorius at about basal third of phallus; cornuti consisting of more than twenty spines of various size.

Female genitalia ( Fig. 24 ): Papilla anale ovate, nearly as long as apophysis posterior. Tergite eight half length of apophysis anterior. Antrum funnel-shaped, with dense granules. Colliculum elongate; ductus bursae anterior to ductus seminalis membranous, with three folds. Corpus bursae rounded, about two thirds longitudinal area covered with dense tiny spines, remaining area covered with dense granules; signum stripelike, placed in granular area; appendix bursae ovate.

Distribution. China (Guangdong, Guizhou, Hainan, Hong Kong, Hunan, Sichuan, Taiwan). Etymology. The specific name is derived from the Latin spinosus = spinous, in reference to the phallus with many small spinelike cornuti in male genitalia.
