Diagnosis. This species can be distinguished from its congeners by the forewing having purple metallic shine, the male coecum narrower than the main part of the phallus ( Fig. 125 ), and the female ductus bursae sclerotized on the posterior 4/5.

Description. Adult ( Fig. 25 ): Wing expanse 17.0−22.0 mm. Vertex yellow, rough; face yellowish white, with innerside blackish brown. Antenna yellowish white on scape; flagellum white, ringed with brown on each flagellomere. Labial palpus light grayish brown, yellow on dorsal surface of basal and second segments; tuft of second segment inconspicuous; third segment about twice length of second. Thorax and tegula brown with purple shine. Forewing with R4 and R5 separated ( Fig. 103 ); brown, with purple metallic shine; dark brown dot at middle and end of cell as well as at middle of fold respectively, inconspicuous in some individuals; cilia dark grayish brown. Hindwing gray, darkened to dark gray toward apex; cilia yellowish gray. Legs grayish white to gray, mixed with brown on tarsi.

Male genitalia ( Fig. 125 ). Uncus an inconspicuous arch. Socius short, blunt at apex. Ventral plate of gnathos narrow tongue shaped, densely covered with teeth. Valva narrow, straight along ventral margin and arched on dorsal margin. Saccus 1.3 times length of socius, narrower basally, with apex slightly pointed. Anellus about a quarter length of phallus, with distal half densely spinous. Phallus about 1.5 times length of valva, straight; coecum narrower than phallus, about 1/3 length of phallus; cornuti about 1/3 length of phallus, composed of two sclerotized spines.

Female genitalia ( Fig. 172 ). Intersegmental membrane between papilla analis and 8th abdominal segment slightly longer than abdomen. Apophyses posteriores 3 times length of apophyses anteriores. Lamella postvaginalis V-shaped. Antrum cup-shaped, strongly sclerotized. Ductus bursae with posterior 4/5 narrow and sclerotized, anterior 1/5 broader, membranous and densely granulous; inception of ductus seminalis at anterior 1/5. Corpus bursae long ovate; signum a sclerotized band, ridged at meddle, slightly pointed at both ends, about a quarter length of corpus bursae.

Distribution. China (Inner Mongolia, Ningxia, Qinghai, Xinjiang). Etymology. The specific epithet is derived from the Latin purpuratus, meaning purple, referring to the forewing having purple shine.
