This species can be distinguished from from its congeners by the forewing having two white fasciae and the white midleg, which are unique in this subgroup. The male genitalia are characterized by the valva with a row of long setae running from basal 3/5 at anterior 3/5 obliquely outward to before costa and the sacculus with a large dorso-preapical spine. The female genitalia are characterized by the ductus bursae with the basal twothirds coiled. Description. Adult ( Fig. 4 ) wingspan 12.5−14.5 mm . Head white, frons yellow laterally, occiput ochrous brown. Labial palpus with first and second segments yellow on inner surface, ocherous brown on outer surface; third segment with dorsal surface and lateral side yellow mottled dark brown, ventral surface white, about same length as second segment. Antenna with scape white; flagellum with dorsal surface white on a few basal flagellomeres, remaining flagellomeres white and black dark brown; ventral surface dark brown. Thorax and tegula ocherous brown. Forewing pale orange yellow, with two white fasciae laterally edged with blackish-brown scales: antemedian fascia from basal 1/5 of costal margin straightly to middle of dorsum; postmedian fascia from distal 1/ 4 of costal margin to before end of fold on dorsum, enlarged in triangle anteriorly; cilia with basal half yellowish brown, distal half deep grey except white around apex. Hindwing and cilia deep grey. Foreleg white ventrally, black dorsally, tibia with a white dorsal spot at about middle and a white tuft at apex, tarsus dorsally white at apex of each tarsomere; midleg white, tarsus distally yellow distally, black dorsally; hindleg white ventrally, deep grey dorsally, tarsus white at apex of each tarsomere on dorsal side. Male genitalia ( Fig. 6 ): Uncus wide at base, narrowed to basal 3/5; distal 2/5 slender, slightly narrowed to blunt apex. Gnathos entirely almost as long as uncus, sub-linguiform distally, with granules on distal 1/4, bearing a membranous apical process; lateral arm wide. Tegumen separated from posterior 1/4, narrowed anteriorly. Valva sub-rectangular, with membranous area mediolongitudinally, forming an irregular membranous band, with row of long setae from basal 3/5 at anterior 3/5 from costa to before apex of costa; apex obtusely rounded, dentate, with long setae. Sacculus with basal 1/2 uniformly wide, distal half narrowed to narrowly rounded apex, with a long slender preapical dorsal process curving obliquely outward. Saccus triangular, shorter than uncus. Juxta inverted triangular; lateral lobe from basal 2/3, thumb-like, with setae distally. Aedeagus stout and straight, slightly shorter than valva, with row of densely compacted short spines about same length as cornutus, with numerous fine spines medially; cornutus strong, conical, about 1/3 length of aedeagus. Female genitalia ( Fig. 9 ). Apophyses anteriores about 1/2 length of apophyses posteriores. Antrum wide, nearly funnel-shaped, posteriorly with deep V-shaped emargination. Ductus bursae longer than corpus bursae, posterior 2/3 weakly sclerotized, coiled, with a tuft of short dense spines and a few scattered short spines, anterior 1/3 membranous. Corpus bursae elliptical, with dense granules; signum small, triangular, bearing three denticles. Distribution. China ( Chongqing , Sichuan ). Etymology. The specific epithet is derived from the Latin albus and pedalis , referring to the white midleg.
