Diagnosis. This species uniquely possesses a thick and short ductus bursae in the female genitalia and strong thornlike cornuti in the male genitalia.

Description. Adult ( Fig. 10). Forewing length 8.0–10.0 mm. Frons pale brown. Vertex pale brown mixed with white. Labial palpus blackish brown; first segment white ventrally at base. 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, thorax and tegula pale brown, with long greyish white scales on posterior margin of tegula. Forewing sparsely suffused with blackish brown scales; antemedian line white, outcurved slightly; antemedian stigmata connected with antemedian line, pale yellow edged by blackish brown, ovate; proximal discoidal stigma and cubital stigma connected with each other, forming 8-shaped pattern; distal discoidal stigma blackish brown, mottled pale yellow on inner side, 8-shaped, connected with blackish brown spot at costa; postmedian line white, meeting costa perpendicularly, dentate towards distal discoidal stigma, posterior two thirds parallel to termen, meeting dorsum by oblique angle; subterminal line white, incurved medially and forming X together with postmedian line; fringe white, with pale brown subbasal line. Hindwing white, pale brown before termen; fringe concolorous with forewing. Legs white, foreleg covered with dense blackish brown scales on outer side, mid- and hindlegs suffused with sparse pale brown scales on outer side; tarsi pale brown to blackish brown and white alternately on outer side. Abdomen grey.

Male genitalia ( Fig. 19 ). Uncus triangular, broad basally, tapering to blunt apex. Gnathos slender, slightly longer than uncus, tapering to distally pointed and hooked tip. Valva broadened towards apex; costa straight; apex rounded. Sacculus slightly concave ventrodistally; free distal process at three fourths of valva. Juxta ovate, slightly concave lateromedially. Phallus straight, nearly as long as valva, with four to five large and two small thornlike cornuti; opening for ductus ejaculatorius at basal third of phallus.

Female genitalia ( Fig. 28 ). Papilla anale ovate, slightly shorter than apophysis posterior. Tergite eight about two fifths length of apophysis anterior. Antrum short tubular, nearly as long as colliculum, covered with dense tiny spines. Ductus bursae short and thick, wrinkled anteriorly, about as long as corpus bursae. Corpus bursae rounded, with sparse tiny spines throughout; signum and appendix bursae absent. Distribution. China (Sichuan).

Etymology. The specific name is derived from the Latin brevitubus = short tubal, in reference to the distinctively short ductus bursae in female genitalia.
