Diagnosis. This species is distinguished by the male having a thin and long, curved, distally hooked cornutus, and the female colliculum with a distinctive annular protuberance.
Description. Adult (Fig. 9). Forewing length 7.0–8.0 mm. Frons and vertex white mixed with pale brown. 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 pale brown dorsally, white ventrally; flagellomeres with dorsal surface pale brown and white alternately, ventral surface pale yellow. Patagium pale brown to blackish brown. Thorax white mixed with pale brown. Tegula pale brown to blackish brown, posterior margin with long greyish white scales. Forewing covered with sparse blackish brown scales; antemedian line inconspicuous white; antemedian stigmata connected with antemedian line, blackish brown: proximal discoidal stigma ovate, cubital stigma stripelike; distal discoidal stigma blackish brown, 8-shaped, connected with blackish brown at costa; postmedian line white, dentate, meeting costa perpendicularly, meeting dorsum by oblique angle; fringe white with pale brown subbasal line. Hindwing white; fringe concolorous with forewing, but subbasal line lighter. Legs white to yellowish white; fore- and midlegs covered with dense blackish brown scales on outer side, tarsi blackish brown and white alternately on outer side; tarsus of hindleg with pale brown to blackish brown dots on outer side. Abdomen grey.
Male genitalia (Figs. 17–18). Uncus fusiform, pointed apically. Gnathos slender, slightly shorter than uncus, tapering to distally pointed and hooked tip. Valva with basal part narrow slightly; costa gently convex, with small slender basal prong; apex rounded. Sacculus narrow triangular; free distal process at about three fourths of valva. Juxta ovate, narrow posteriorly. Phallus straight, nearly as long as valva; opening for ductus ejaculatorius at about basal third of phallus; cornutus thin and long, curved, distally hooked.
Female genitalia (Fig. 27). Papilla anale broad anteriorly, tapering towards rounded tip; as long as apophysis posterior. Tergite eight about half as long as apophysis anterior. Antrum short tubular, slightly thicker than colliculum, covered with dense granules. Colliculum about third length of ductus bursae, with annular protuberance anterolaterally. Ductus bursae constricted conspicuously for short distance before colliculum, then thickened towards corpus bursae. Corpus bursae rounded, covered with dense small spines; signum stripelike; appendix bursae ovate.
Distribution. China (Gansu, Hubei, Shaanxi, Sichuan).
Etymology. The specific name is derived from the Latin uncinatus = uncinate, in reference to the cornutus ending with a unique hook in male genitalia.
Remarks. This species varies in the male genitalia. In some specimens, the sacculus is straight on ventral margin, and the cornutus is curved slightly at base and middle, ending in a large hook (Fig. 17); in other specimens, the sacculus is concave at middle on ventral margin, the cornutus is curved in N shape, ending in a small hook (Fig. 18).
