Diagnosis. The speicies can be easily distinguished from others by its wings mostly coved with brown scales and the androconial hairs in male covered with the whole cell from the upper edge. In male genitalia, it is characteristic by its strong specialized setae about 3/5 length of valva, all with expanded apex, third seta with minute spines laterally. In female genitalia, it is special by the ductus bursae about the same length of corpus bursae, and corpus bursae with a pair of broad signa, about the same length of corpus bursae.

Male genitalia ( Fig. 37 ). Uncus slender, apex pointed; gnathos about 2/3 length of uncus, apex with several dorsal teeth; tegumen with sclerotized dorsal ridge X-shaped; valva densely covered with setae, nearly same width from base to apex, three strong specialized setae present at apex, about 3/5 length of valva, all with expanded apex, third seta with minute spines laterally; vinculum broad; saccus round; juxta plate-like, with two spiniform apexes; aedeagus strong, vesica with many minute spines, ductus ejaculatorius arising from middle.

Female genitalia ( Fig. 38 ). Anal papillae relatively narrow, densely covered with setae; apophysis anterioris and posterioris near same length; antrum cylindric; collar sclerotized; ductus seminalis arising below collar; ductus bursae about same length of corpus bursae, with many minute spines; courpus bursae membranous, with a pair of broad signa, consisting of many minute spines, about same length of corpus bursae.
