Diagnosis. Scoparia sinensis is very similar to S. spinata in the wing pattern and male genitalia, but can be distinguished in the female genitalia by the thumblike protuberance in the anterolateral one fourth of the colliculum and the anteriorly curved ductus bursae that is sclerotized between the anterior sixth and halfway. In S. spinata , the colliculum bears a semicircular protuberance in the middle, and the ductus bursae is straight and membranous anterior to the ductus seminalis.

Redescription. Adult ( Fig. 1 ): Forewing length 7.0–8.0 mm. Frons pale brown. Vertex pale brown mixed with white. Labial palpus blackish brown except first segment white ventrally at base. Maxillary palpus blackish brown, white basally, tip mixed with white. Antenna with scapus pale brown dorsally, white ventrally; flagellomeres with dorsal surface pale brown and white alternately, ventral surface pale brown. Patagium and thorax pale brown. Tegula pale brown to blackish brown, posterior margin with long, pale brown-tipped white scales. Forewing basally with blackish brown stripe; antemedian line white, outcurved slightly; antemedian stigmata filled with ochreous, edged with blackish brown, ovate, connected with antemedian line; distal discoidal stigma 8-shaped, black-edged, filled with white and ochreous, connected with blackish brown spot at costa; postmedian line white, meeting costa and dorsum perpendicularly, conspicuously dentate towards distal discoidal stigma, posterior third outcurved with small dentation; subterminal line white, medially incurved conspicuously, forming X together with postmedian line; fringe yellowish white, with pale brown subbasal line. Hindwing white, suffused with pale brown towards termen; fringe concolorous with forewing except lighter subbasal line. Legs white; foreleg covered with dense blackish brown scales on outer side; mid- and hindlegs covered with sparse blackish brown scales on outer side; tarsi blackish brown and white on outer side alternately. Abdomen pale brown.

Male genitalia ( Fig. 3 ). Uncus triangular, broad at base, tapering to blunt apex. Gnathos slender, slightly shorter than uncus, pointed and hooked apically. Tegumen nearly as long as gnathos. Valva narrow basally, broadened towards rounded apex; costa gently convex near middle. Sacculus concave ventrodistally; free distal process at about two thirds of valva. Juxta ovate, more or less concave lateromedially. Phallus straight, thin at base, thickened towards tip, nearly as long as valva; opening for ductus ejaculatorius at about basal third; with two groups of cornuti, each group consisting of several spines of various size.

Female genitalia ( Fig. 4 ). Papilla anale ovate; about half as long as apophysis posterior. Tergite eight about third length of apophysis anterior. Antrum funnel-shaped, covered with dense granules, much thicker than colliculum. Colliculum about half length of ductus bursae, anterior one fourth constricted and folded inwards, lateral margin with thumblike protuberance. Ductus bursae with anterior third curved, its median part sclerotized. Corpus bursae rounded, about half longitudinal area covered with dense tiny spines, remaining area covered with dense granules; signum stripelike, placed in granular area; appendix bursae ovate.

Distribution. China (Guizhou, Hubei, Shandong, Sichuan, Zhejiang).

Remarks. Leraut (1986) described S. sinensis based on a single female, but did not provide an image of its wing pattern. We describe and illustrate this species in detail herein.
