33. Argyresthia (Argyresthia) scalprata , sp. nov. ( Figs. 42 View FIGURES 36 – 43 , 111 View FIGURES 108 – 113 , 167 View FIGURES 166 – 169 , 223 View FIGURES 221 – 232 )

Description. Adult ( Fig. 42 View FIGURES 36 – 43 ) wingspan 12.0 mm. Head grayish white. Labial palpus white, mixed with gray laterally. Antenna with scape white, pecten yellowish fuscous; flagellum grayish white, ringed with blackish fuscous. Foreleg with femur gray on inner surface, tibia and tarsus blackish fuscous, remainder yellowish white; mid- and hindleg mostly yellowish white, hind tarsus gray on each tarsomere distally. Thorax grayish white; tegula brownish fuscous. Forewing ratio 4.0; ground color yellowish white; costa with several black dots on basal 3/10, black spot at middle largest, two or three black transverse striae on distal 3/10; blackish-fuscous spot before middle of cell, blackish-fuscous dot at lower angle of cell and at tornus, the latter larger; blackish-fuscous streak below basal 1/3 of fold; dorsal fascia from before middle of wing blackish fuscous, reaching distal 2/5 of costa; cilia yellowish white mixed with black, grayish white near tornus. Hindwing and cilia gray.

Male genitalia ( Figs. 111 View FIGURES 108 – 113 , 167 View FIGURES 166 – 169 , 223 View FIGURES 221 – 232 ): Tuba analis shorter than width of valva. Socius covered with 15–16 scale-like setae, bearing two setae posteriorly ( Fig. 223 View FIGURES 221 – 232 ). Gnathos not inflated distally, without long thick setae apically. Valva knife-shaped, with basal half uniform in width, distal half triangular, narrowly rounded at apex; a row of thick setae in disc near ventral margin to distal part. Saccus broad, uniform in width, as long as width of valva, as wide as 3/5 width of valva, rounded apically. Phallus arched, 4.5 times as long as width of valva ( Fig. 167 View FIGURES 166 – 169 ).

Distribution. China (Sichuan).

Diagnosis. The male genitalia of Argyresthia (A.) scalprata are unique among all congeners in having a knifeshaped valva and a broad saccus. This new species resembles A. (A.) ivella (Haworth, 1828) in the shape of the saccus, but it can be separated easily by the distinct shape of the valva.

Etymology. The specific name is derived from the Latin scalpratus, meaning knife-shaped, referring to the knife-shaped valva in the male genitalia.
