Scoparia metaleucalis Hampson, 1907: 23 View in CoL . Type locality: Sichuan Province, China.

Diagnosis. Scoparia metaleucalis is similar to S. spinata in the female genitalia by the semicircular protuberance of the colliculum, but can be disparted by the protuberance arising from the anterior margin of the colliculum; whereas the protuberance of S. spinata arises from the middle of the colliculum. In male genitalia, S. metaleucalis is conspicuously different from S. spinata by the ovate uncus, the ventrobasally convex sacculus and the cornuti consisting of a row of small spines and a cluster of large spines, the latter surrounded with many tiny spines; whereas in S. spinata , the uncus is triangular, the sacculus is straight ventrobasally, the phallus bears two clusters of cornuti, neither of them surrounded with any tiny spine.

Redescription. Adult ( Fig. 5 View FIGURES 5 – 8 ): Forewing length 7.0–8.0 mm. Frons and vertex pale brown mixed with white. Labial palpus blackish brown; first segment white ventrally at base. Maxillary palpus blackish brown, white distally. Antenna with scapus pale brown dorsally, white ventrally; flagellomeres with dorsal surface pale brown and yellowish white alternately, ventral surface pale yellow. Patagium pale brown mixed white. Thorax white to grey. Tegula blackish brown, posterior margin with long white and pale brown scales. Forewing with sparse blackish brown scales, basally with short blackish brown stripe; antemedian line white, outcurved slightly; antemedian stigmata blackish brown, stripelike, connected with antemedian line; distal discoidal stigma blackish brown, X-shaped, connected with blackish brown spot at costa; postmedian line white, meeting costa and dorsum perpendicularly, dentate towards distal discoidal stigma, bent inwards in small dentation near dorsum; subterminal line white, interrupted medially, forming X together with postmedian line; fringe white, with pale brown medial line. Hindwing white; fringe white. Legs white, covered with sparse pale brown to blackish brown scales on outer side; tarsi pale brown to blackish brown and white alternately on outer side. Abdomen grey.

Male genitalia ( Fig. 13). Uncus ovate. Gnathos slender, slightly longer than uncus, armed with tiny dentations. Valva narrow; costa gently convex; apex rounded. Sacculus conspicuously convex ventrobasally and concave ventrodistally; free distal process conspicuously hooked, at about three fourths of valva. Juxta ovate, posterior one fourth with V-shaped notch, covered with dense granules medially and dense small spines laterally. Phallus curved slightly, slightly shorter than valva; opening for ductus ejaculatorius at about basal one fifth of phallus; phallus with two groups of cornuti: one group consisting of more than ten small spines arranged in a row; second group consisting of six large spines arranged in a cluster and surrounded with many tiny spines.

Female genitalia ( Fig. 23 View FIGURES 23 – 25 ). Papilla anale ovate, slightly shorter than apophysis posterior. Tergite eight about half as long as apophysis anterior. Antrum short tubular, covered with dense granules. Colliculum curved at anterior third, anteriorly with sclerotized semicircular protuberance. Ductus bursae straight, thickened towards corpus bursae. Corpus bursae rounded, about one fourth longitudinal area covered with dense tiny spines, remaining area covered with dense granules; signum ovate, placed in granular area; appendix bursae rounded.

Distribution. China (Sichuan).

Remarks. Hampson (1907) described the external characters of S. metaleucalis based on a male specimen, but did not provide any image. We provide the image and describe the female for the first time.
